Replying to your inquiry concerning the two "Paragon" propellers purchased from you for my Bleriol type of monoplane, I am pleased to say lhal ihe second is, if possible, even more satisfactory than the first. The 8-fool propeller that you first furnished carried the machine into the air six limes out of the seven attempt* made with it and gave every promise of good results in extended flight before it was destroyed in the untimely collision lhal wrecked the wings of the machine, tj After rebuilding the machine 1 have tried three or four other propellers of other manufacture but was unable to get the machine clear of the ground until 1 put on the new 8' 6" " Paragon propeller received from you a few days ago. This new propeller seems to suit ihe machine perfectly and we expect to make some record breaking flights very soon. 1 attribute the success of my machines in no small measure to the skilfully designed and handsomely built propellers obtained from your company. <J Please furnish me four more propellers in duplicate of the one last furnished and upon the same terms.

cAeronautics

THE importance of holding international contests in America cannot be overestimated. The progress of aeronautics in this country must depend largely upon individual or corporate initiative. The government may be relied upon to do its part.

There is a strong feeling in aeronautical circles that it has thus far been too conservative. This may possibly be true, but the matter has not been altogether neglected. It has been considered by the executive and discussed in congress, and the secretary of war, in his report for this year, says:

But whatever may be the influence of aerial locomotion upon the art of war, whether or not it will ever prove a valuable auxiliary to armies in the field, the fact must be recognized that all first-class powers except the United States are providing themselves systematically with aerial fleets.

UNITED STATES A LIBERAL PURCHASER.

The aeroplane problem is self-developing. Owing to the low cost of constructing the machines, smal companies and even individuals of moderate means can afford the cost of the experimental work. Of course, inventors and manufacturers must have customers for their creations, and they will no doubt find many private ones, and I am sure the government will, a little later on, be a liberal purchaser.

GREAT COST OF THE DIRIGIBLE.

With the dirigible balloon, however, conditions are somewhat different. Owing to the great cost not only of the balloon, but of the necessary garages and gas plants, it will almost necessitate government aid. However, in Germany and France, where the greatest progress has been made, personal initiative and money contributed by the people have been the controlling factors.

After the loss of the first Zeppelin, the German people in a few days gave $1,500,000 to Count Zeppelin to rebuild his ship, and very recently, after the disaster to "La Re-publique," the French people contributed liberally and quickly, and the manufacturers charged only the actual cost in constructing a new ship.

Germany's aerial fleet.

Methodically, as a w'hole, Germany has constructed an aerial fleet. She now possesses 10 military dirigibles of large tonnage, and 15 private dirigibles. But, what is more important, she is also prepared to construct [) them rapidly.

In addition to the Zeppelin balloon, the government has permitted to be constructed, by its engineer officers, dirigibles of the "Gross" system, and powerful means of operation have permitted Major Parseval to build airships of this type. Other inventors have realized more modestly but surely their ideas, and stock companies having as subscribers the large cities of Germany, have established a

allen

large capital for the exploitation of various systems.

During this time the German government has organized success by co-ordinating or affiliating the different efforts.

HYDROGEN CHEAPER THAN COAL GAS.

It has prepared as a public utility pure hydrogen gas, which up to that time was an unused by-product, from chemical factories. In addition to saving this hydrogen gas as a by-product, the German government has also established large factories for the manufacture of hydrogen gas by means of what is known as the "water gas" process. This is said to be manufactured in Germany at 50 cents per 1,000 cu. ft.

It has placed in depots in these factories thousands of bottles of hydrogen, painted in gray with the imperial arms.

In a single one of these storehouses, that of Grisheim, near Frankfort, there is in a storage depot not only 15,000 bottles always filled, but in addition two trains composed of vehicles loaded with bottles connected in series to a common stop-cock. Each train embraces a repair vehicle. These vehicles in case of need leave by the quickest routes and superior orders are given by which they can be attached even to the imperial train.

At another station—-Bickendorff—large provisions of hydrogen (one depot alone contains up to 3,530,000 cu. ft. of gas have been formed. Upon the least alarm given of an unexpected landing, wagons loaded and carrying each over 100,000 cu. ft. of hydrogen, are ready to be attached to an express train to take them immediately as near as possible to the dirigible in distress.

This is not all. The government has constructed at the same time immense sheds and garages. Those at Cologne and at Metz each shelter six Parsevals of 6,700 cubic meters capacity (235,000 cu. ft).

THE NEW ZEPPELIN MONSTER.

The latest information from abroad states that the new Zeppelin will be 984 ft. long and will carry 360 people. It will contain

EDITOR'S XOTE:—Mr. Sellers has the distinction of flying with less power than any other experimenter. His motor (jives but 5 b. h. p., yet lie lias made several hundred short flights zvith his four-deck machine.

DURIXG the last two years several kinds of lateral control have been tried on my machine, and a brief account of some of them may be of interest. These devices have been tested to some extent in short flights. There is a drawing of my glider in aeronautics of October, 1909, page 130. A feature which contributes to lateral stability is the vertical keel, which is above and behind the planes; this, coupled with the low center of gravity, tends to keep and restore equilibrium. An objection to this vertical surface above the planes is that it tends to upset the machine when struck by a side gust; but on the whole it tends toward safety.

The front spars of my planes are rigid and form part of the framework: the rear spars are supported by props or other devices; and in this glider these supports are yielding, allowing the rear of a wing to tip up under abnormal pressure, thus helping to stabilize

eight motors, four for use and four for reserve. The first line of the Zeppelin Airship Co. to be opened is from Hamburg by way of Cologne to Baden Baden ; the second from Hamburg to London. The first "Zeppelin" made its ascent in July, 1900, so that 10 years have been spent in attaining the present proficiency.

THE MILITARY MORAL.

The moral of all this is that every nation will have to serve a long and arduous apprenticeship in the new art, establish practical schools, build many experimental vessels, encourage amateur talent, enlist the aid of aeronauts and engineers, and spend considerable sums spread over a number of years. Success may then come quite rapidly, but it never can be had at a moment's notice by spending a large sum of money at the moment of emergency.

It is agreed by all military authorities that the only way of effectively opposing military airships is by means of airships. It is not considered possible to protect against airships by stationary guns from the earth. This new weapon of war is now a part of the military establishment of the principal world powers, which this country has at present no means of combating either at home or in case of

operations abroad. It is entirely practicable to-day, with a single dirigible balloon or a few aeroplanes, to destroy by means of explosives, and particularly incendiary mixtures, the shipping of any of our large sea-coast cities, as well as property of enormous value, against which this government has not yet provided means to protect itself.

It has never been the policy for the United States to maintain a large military force, but it has been the policy to furnish the American army with the latest and best types of war material as fast as they are developed— namely, the best guns, ammunition and equipment of all kinds—and there is no doubt but that it will continue this policy with reference to aeronautics and will provide the army and navy with an ample supply of the best aero nautical devices known or that can be devised and constructed.

Mere lies an unlimited field for patriotic endeavor, for creative genius to devise, for young men to study and practice the art of navigation of the air, for men of wealth to aid the inventor and students of the art, for municipalities to provide aeronautical parks, and for corporations to start lines of airships, both dirigibles and aeroplanes, or some combination of these.

the aeroplane. While this arrangement did not work as well as expected, it did produce a decided improvement in stability.

Last spring T tried a device, first used on my kite in 1903, viz.: T connected the rear spar at one end of a plane, with the rear spar at the other end, by a cord running over pnl leys, so that when a gust would tip up the right wing end, it would pull down the left one. On the kite a similar device caused it to weave about, and its use was discontinued; but on the aeroplane this tendency could be corrected by the rudder. It seemed, however, that the action was too erratic, so, to improve it, T connected the cord leading to the two ends of the wings to a hinged vertical plain-, so that when a side gust would turn the vertical plane, it would depress the leeward wing and slacken the windward one, as shown in Fig. 1. Tn the few imperfect trials made, it seemed to work well; but it acts exactly wrong when making a turn, so that there should also he provision for positive control. At present 1 am testing a positive lateral control, which T believe is new; that is, by twisting a horizontal or vertical rear rudder. On my present machine I am applying it to a high (i. e., wide) vertical rudder. This rudder, shown in Fig. 2, is hinged or fastened to a post (p), and the cords (A, B, C. D) lead to the steering device. By pulling cords A and B and slacking C and D, the rudder is twisted as shown: while by pulling A and D, it is merely turned. These operations are produced by simple movements of the steering device. A modification, simpler but less effective, is to have the upper point (O, Fig. fixed and steer or stabilize by turning the lower corner by the lines B and D.

The Chanute Launcher

A patent was taken out on this to keep it out of the hands of irresponsible persons. Mr. Chanute is willing to grant licenses gratis to parties giving assurance of cautious experimenting.

Air. Chanute describes the method of operation as follows :

"In practicing my invention the track, preferably portable, is generally laid in the direction of the existing wind and the car, preferably a light platform-car, is placed on the track. The truck carrying the winding-drum and its motor is placed to windward a suitable distance—say from two hundred to one thousand feet—and is firmly blocked or anchored in line with the portable track, which is preferably eighty or one hundred feet in

whether he stands upright and carries it 011 his shoulders, or whether he sits or lies down prone upon it, adjusts the aeroplane or carrying surfaces so that the wind shall strike them on the top and press downward instead of upward until the platform-car under action of the winding-drum and line attains the required speed.

"When the operator judges that his speed is sufficient, and this depends upon the velocity of the wind as well as that of the car moving against the wind, he quickly causes the front of the flying-machine to tip upward, so that the relative wind striking on the under side of the planes or carrying surfaces shall lift the flying machine into the air. It then ascends like a kite to such height as may

/ /

be desired by the operator, who then trips the hook and releases the line from the machine. The operator being now free in-the air has a certain initial velocity imparted by the winding-drum and line and also a potential energy corresponding'to his height above the ground. If the flying or gliding machine is provided with a motor, he can utilize that in his further flight, and if it is a simple gliding machine without motor he can make a descending flight through the air to such distance as corresponds to the velocity acquired and the height gained, steering meanwhile by the devices provided for that purpose.

"The simplest operation or maneuver is to continue the flight straight ahead against the wind : but it is possible to vary this course to the right or left, or even to return in downward flight with the wind to the vicinity of the starting-point. Upon Hearing the ground the operator tips upward his carrying-surfaces and stops his headway upon the cushion of increased air resistance so caused. The operator is in no way permanently fastened to his machine, and the machine and the operator

simply rest upon the light platform-car, so that the operator is free to rise with the machine from the car whenever the required initial velocity is attained.

"The motor may be of any suitable kind or construction, but is preferably an electric or gasolene motor. The winding-drum is furnished with any suitable or customary rcvers-ing-guidc to cause the line to wind smoothly and evenly upon the drum. The line is preferably a cable composed of flexible wire and having a cotton or other cord core to increase its flexibility. The line extends from the drum to the Hying or gliding machine. Its free end may. if desired, be grasped and held by the operator until the flying-machine ascends to the desired height, when by simply letting go of the line the operator may continue his flight free. The line, however, is preferably connected to the flying or gliding machine directly by a trip-hook having a handle or trip lever within reach of the operator, so that when he ascends to the required height he may readily detach the line from the flying or gliding machine."

THE Greene biplane shows good workmanship throughout. It will no doubt find a good sale among those who are not anxious to enter into litigation, for there are no warping of surfaces nor use of wing tips. The design is original, and does not resemble any other machine on the market. Following are some details. Dimensions are given in sketch.

Main Planes.—-The main cell divides into five sections by simply unfastening wires and the triple nickel-plated strut sockets. At each lateral extremity there is a vertical surface, as in the Voisin machine, with two others at the next inner struts respectively. Each lateral beam is in pieces, the longest of which are 6 ft. All the struts are laminated spruce, as are also all ribs. The struts are very small fish-shaped, measuring }i in. by 1^5 in. There are four layers of wood, stained mahogany and varnished. The ribs have each 3 laminaa, except those which come at the five sectional divisions, which are somewhat heavier. Naiad silk is used underneath the ribs. At the section points the cloth is laced to the big ribs.

Other Surfaces.—The tail has two rigid vertical surfaces. Between these is a fixed horizontal surface. On top of this is a movable vertical rudder. Tn front of the main cell is the horizontal rudder 9 ft. spread by 28 in. fore and aft. This is actually higher than the top plane.

Poller Plant.—A rebuilt Curtiss 8-cylinder air-cooled engine, rated at 40 h. p., and similar to that used in the June Bug, drives direct a 6 ft. Greene two-bladed propeller. Instead of eight carburetors, manifolds have been attached to the motor so that but two carburetors were used. The weight without any accessories, except timer, showed on the scales 165 lbs. The propeller gave 230 lbs. push at 1.260 r. p. 111. Ignition is by battery and coil. The upper and lower surfaces are cut away at the

rear to make room for the revolution of the propeller.

Mounting.—The whole machine rests on two 20-inch wire wheels in combination with two skids, fitted with spring shock absorbers.

Controls.—The front rudder is operated by pushing forward or pulling back-on a rod; the rear vertical by turning the steering wheel in the generally accepted way. On the wheel is the gas throttle and spark cut-out.

Stability.—This is inherent in the surfacing, it is claimed, the "side curtains" adding thereto and preventing too much skidding.

The weight without motor or aviator is about no lbs. The machine stands at a very steep angle. As soon as the propeller is started it raises the tail and sets the machine at its flying angle. As soon as speed is attained the machine raises without tilting the front control. In landing, the rear of the skids acts as a brake and stops the machine almost within its own length. The whole apparatus packs into two comparatively small boxes.

On completing the construction of the machine Dr. Greene calculated the theoretical center of gravity, and had the aeroplane placed on a fulcrum at points which he had marked 011 the skids. It promptly rose to an even keel and balanced almost to certainty.

Xo wires arc used in the machine. Specially woven fine steel cable takes its place.

I!! Construction Aids

xii.

The Mleriot machine brought over by Saul nier has been returned to France. The Wrights started a suit when the machine arrived, no exhibitions were given and Sanlnier got into financial difficulties and was assisted by L. Lewkowiez.

J. \V. Curzon, who imported a Farman ma chine, has been making trials at the Motor Speedway at Indianapolis. He has made sev eral flights of about five-eighths of a mile, but has not yet been able to turn very well. In the past he has been having engine trouble.

sliding panels shown to be efficient. As he was about to alight, with lessened speed and headway, a gust of wind struck him from the left, twisting the machine quickly to the right and tipping the right wing down until it nearly touched. Pfitzner instantly speeded up the motor, raised the elevator, turned his rudder to the left and shot out the right panel and the machine was again on an even keel.

Flights by Greene Aeroplane.

Mineola, L. I., April I.—R. W. Crosby, of San Francisco, made his first flights to-day in the Greene aeroplane he purchased on coming east a short while ago.

After a long delay in getting a motor fitted Dr. Win. Greene gave his new type biplane its first try-out. The first flight was from Mineola to' the Motor Parkway, about \l/2 miles. Then Dr. Greene announced he would demonstrate the machine in accordance with the contract. From the Parkway a circular flight of about 2 miles was made, proving the stability of the machine without the use of wing tips or warping. The wind was about 7 to 8 miles an hour. After accepting delivery Crosby got in it himself for the first time and flew it back to the start, a distance of \l2 miles, shutting the motor off when he-was 30 ft. in the air. He made the remark, ''I didn't know when it struck the ground, it glided so gently to the ground." Fleven other flights were made by him, of varying lengths.

The' breeze did not seem to bother the machine, which flew on a remarkably even keel, and there seemed to be no trouble in turning.

The aeroplane was immediately disassembled and shipment made to San Francisco, where further flights will be made.

Four more aeroplanes are in course of construction by the Greene company. One is nearly ready. These are all duplicates of the one sold to R. W. Crosby. Two Greene machines are now flying in this country. A factory, 50 by-100, is to be contracted for at Mineola. One point is of particular interest, and that is that the Greene machine does not infringe the Wright, patent.

Pfitzner Monoplane Flying Again.

On April 5th, while making his 14th flight of the day on the grounds of the Country Club at Buffalo, N. Y., A. L. Pfitzner met with a mishap. In making a quick change in his course a gust of wind unstabilized the machine and it landed on the front control and right wing. Mr. Pfitzner was not any worse than severely bruised.

The machine had been taken from 11am-mondsport, where it was built, to the Sportsmen's Show at Buffalo and afterward to the Country Club- On April 2 three flights were made but a slight accident was had on the last. On the 5th r3 flights were made almost as fast as the machine could be flown up and down the field. In one particularly, was the

AEROPLANE FROZEN IN THE ICE.

For the first time an aeroplane has been frozen in the ice. During the trial flights on Lake Keuka, one afternoon, the ice had softened under the sun's rays and on starting up, the aeroplane broke through the ice. Of course, the wings remained above. Mr. Pfitzner and his men broke through the ice several times and they had to hang on to the wings. The next morning the ice was solid again and the machine was cut out with an axe.

Moore Making More Monoplanes.

As can be seen from the photograph, tln> machine, built by R. S. Moore, 1438 Columbia Rd., Washington, D. C, is of the Bleriot type, with the difference that in the Aloore machine the operator is seated below the main planes, while Rleriot sits above them.

The dimensions are: 26 ft. from tip to tip. wings being 12 ft. long with 2 ft. space of frame, 6 ft. 3 in. chord, length of frame 22 ft., rear elevating plane 3 by 8 ft. and rudder is 3 by 3 ft. The length is 24 ft. The motive power at present used is a five-cylinder 36 h. ]). • Adams-Farwell revolving motor, which is connected to the propeller with the usual countershaft. The total weight without man is 260 lbs.

Experimental flights are now being made at Ft. Myer. Through the kindness of Mr. Moore we will be able to give complete details of the new machine in the near future.

The new machine now building will be equipped with a five-cylinder Berliner revolving motor of 35-40 h. p., which has been tested for \l/> hours with load. This monoplane will have many new features.

Paulhan Back Home.

Aviator Paulhan, the former mechanic, now world's record holder in aviation, has returned to that dear France with no very kind feelings toward America, and the Wrights in particular.

He made one good flight, on March r,3, at the Jamaica track on Long Island before leaving. In the puffy, strong wind it was sensational, though it lasted but eight minutes. Paulhan had considerable trouble with his backer, Edwin Cleary, and in the end the machines were placed under the control of the courts and are still in this country. Mr. Cleary may possibly bring over other machines which do not infringe and try to recoup his enormous losses sustained during the Ameri can tour of his aviatorial prima donna.

First German Aeroplane Pilot.

August Euler, through his trial flights of December 31, 1909 (three flights of 7 km. in two complete circles) gained the distinction of being the first German aviator to receive an aviation pilot license from the German Airship Society.

His machine is the first machine of German make of this particular itype. This machine has 50 sq. meters surface in the planes, including the tail and elevator.

The total weight of this machine is 238 kgs. There are three steering planes in the tail and at each rear edge of the lower surface is a triangular "wing tip" for stability. The motor is a rotary 8-cylinder 55 h. p., fitted with a U. H. Master Magneto. The propeller of this apparatus is 2.60 m. diam. The spread of planes 10 m. The total height is 9 m.

Canadian Monoplane Flies.

The monoplane completed by the Canadian Aerodrome Co. for Gardiner G. Hubbard of Boston has had its first successful trials.

After waiting some days for propitious weather, on the morning of April 5 nine beautiful flights were made over the ice of Bras d'Or lake, in Nova Scotia, near Dr. A. Graham Bell's estate. These lasted from 10 to 15 seconds each, elevation about 10 ft. It worked splendidly and was handled so well by Mr. Hubbard in these, his maiden flights, that no damage to the machine resulted either in landing or rising.

UESCKUTION OF MACHINE.

In this machine are embodied features found in both the Bleriot and Antoinette types. Cleanness of lines has been the goal; and to arrive at this end the engine has been placed completely inside the body and the propeller shaft driven by chain and sprocket in the ratio of 3 to 5. The power plant is identically the same as that used in the Baddeek 11, viz., a Kirkham 6-cylinder motor, water cooled, developing 40 b. p. at 1,400 and 48 at 2,000 r. p. m. The weight of this motor is 320 pounds. The only difference so far as the propeller is concerned lies in the fact that the monoplane propeller pulls, while the Baddeck II pushes.

The dimensions are as follows: Spread, 34 ft., and length, 30 ft. 2 in. This gives a total supporting surface of 260 sq. ft. and the weight of the machine without aviator, but including the engine, about 1,000 pounds. This gives a flying weight ratio of 3.8 pounds per square foot of surface.

The ice is now completely gone and the winter's program is over. Three out of the five machines built by Messrs. McCurdy and F. W. Baldwin have flown.

Joseph Seymour, crack automobile driver, has purchased the Cnrtiss aeroplane from A. P. Warner for exhibition purposes.

Wright Training School Starts.

A Wright aeroplane arrived at the Wright Co.'s training camp, just out of Montgomery, Ala., on March 19. With it were three men, Charles E. Taylor, J. W. Davis -and W. R. Brookins. Three flights were made on March 28. The engine continually gave trouble. On the final flight, after 15 minutes in the air, the piston broke at an altitude of about 100 ft. and a successful landing made. Brookins was the pupil. Orville Wright is instructor.

The public has been given permission to view the flights, provided it does not encroach upon the field to get in the way of possible forced quick descents.

J. D. W. Lambert, brother of A. B. Lambert, president of the Aero Club of St. Louis, is to purchase a Wright aeroplane, to be delivered in the fall. Lambert expects to commence his training at the Wright aviation school, near Montgomery, Ala., in April or May.

Flight in Evansville.

L. C. Wolfe, of Evansville, Ind., an official of the L. & N. R. R., got in a Curtiss type aeroplane built by Geo. B. Haddock, of Cincinnati, and owned by a circus, and at once left the ground and made a good flight of about half a minute, but grazed a fence in landing. Haddock had been having engine trouble and had just finished installing tin automobile motor.

Army Aeroplane Flying.

The damage to the Signal Corps Wright aeroplane, due to rough handling on March 2, was easily repaired and flights as follows were made: March 12, five flights, 8l/2, 15, 4, 12 and 16 mins.; March 17, three, 6, 5V2 and 7 mins.; March 21, one of 13 mins. Strong winds of from 18 to 45 miles an hour prevented flights 011 other days. The number of windy days was 22, the good days 9, during March. In all, 14 flights were made during the month, with a total of 170 minutes and 22 seconds in the air.

The Beach Bleriot-type Monoplane.

One of our illustrations on page 172 shows the Bleriot-type monoplane of Stanley V. Beach, equipped with its new wings. these have a much greater curvature than the wings formerly used, and they are wider and loifger than the wings Bleriot uses on this No. 11 monoplane. They have a supporting surface of 224 sq. ft. and are loaded to slightly more than 3 lbs per sq. ft. Mr. Beach, now that he has transferred his machines to his home at Stratford, Ct. (where he is continuing his experiments), has incorporated a new company in Connecticut, known as The Scientific Aeroplane Co. He is experimenting with a new device for automatic stability, of which we will have more to say in our next issue.

Many Machines Building at St. Louis.

H. A. Robinson has ordered an Elbridge 40 h. p. motor, which is due in St. Louis April 14. He has not materially altered his monoplane, which failed to fly last fall on account of lack of sufficient power, and will be ready to try it again with the new motor, about April 20.

W. F. Zeller has a monoplane completed and is waiting for his motor to be finished. He expects it in less than two weeks, and will be ready April 20 "for his trip," as he expressed it. Zeller believes that he will be able to fly to Xew York before summer is over.

William Frank has completed a monoplane and has nearly finished the 40 h. p. motor which will be installed. He will have the craft ready for the air April 15.

Clarence Williams will have his monoplane ready for trials April 30. Mark Fisher set May T as the date when he would have his curved plane apparatus ready for the air. Thomas W. Renoist will have his third biplane ready for trials in May. His second biplane is completed, but he is not satisfied with it.

Frederick Van Blarcom has ordered a more powerful motor built to his specifications which he will install in the monoplane which he was unable to drive successfully in the trials last week. Tie stated that the motor has been promised him within two weeks, but sets April 21 as the date when he will be ready to go out with his plane.

Will Y. Haggart has a monoplane nearly completed in sections, and is in search of a place large enough for an assembly room. He could be ready in two or three weeks. Alfred Kuhne has a monoplane completed, which is his third endeavor to build a successful machine. He needs a motor.

W. Fears, 4125 Green Lea place, stated that he had successfully built what he calls a "four-in-one" motor of 25 h. p., weighing 70 pounds. He offered the use of the motor to any member of the association for a trial about Mav 1. provided the experimenter guarantees him against loss or destruction of the motor.

E. Percy Noel, well known as a writer and lecturer on aeronautics, who is secretary of the Aero Club of St. Louis and aero editor of the St. Louis Globe-Democrat, was the fir^t person out of the 750,000 who live in St. Louis to ride in an aeroplane. Noel went to Mem nhis to see the flying and stayed to ride with Curtiss on April 8.

Charles J. Strobel of Toledo, flic airship magnate, has bought a Blerint machine and is making a couple of copies of his Curths for exhibition work.

At the Montreal automobile show there

were two aeroplanes exhibited. The Bleriot

and Antoinette type machines of S. Y. Beach

were rented to Manager E. M. Wilcox for the week.

Curtiss Flies at Memphis.

by e. f. stephenson.

Memphis, Term. April ro.—For five days G. H. Curtiss, C. F. Willard and "Bud" Mars, who has graduated from ballooning to the aviation class and is flying a Curtiss machine, have given Memphis an all-star show. On the 6th the wind blew a gale, and Curtiss and Willard made each several short jumps.

On the second day Curtiss circled the race track on several occasions and made passenger flights, taking up "Bud" Mars on one and Mrs. Curtiss on the other, the first for Mrs. Curtiss. Once, in coming down, he had to steer the machine into a fence, but didn't smash anything.

Willard made some nice short flights, and did some spectacular gliding.

new world record.

The crowd looked for sensations every minute, but the conditions of the grounds rendered such flying dangerous, if not impossible. Later in the day Curtiss got off ground in 5 4/5 seconds, making a new world record, using the 8-cylinder machine. In the last flight of the day Curtiss arose in front of the grand stand and Willard from the field. Neither knowing the other was ready to fly, they met just north of the stand, Curtiss passing under Willard, amid the plaudits of the crowd.

The third day Curtiss made two-passenger flights, carrying George B. Walthen and E. Percy Noel of St. Louis. Curtiss later tried to beat the record made the day before, but only tied it. His distance was 143 ft. 11 in. Willard made several flights. Mars made several splendid flights, winning his way to the hearts of the crowd. This young fellow is destined to become a good aviator.

On the fourth day Mars made the most sensational flight of the meeting. Leaving the ground in front of the.sheds and making a complete circuit of the course at an altitude of about roo ft., alighting amid great applause. Willard followed in a few minutes, but at the upper end of the course, in making the turn, his machine skidded, and, finding he was unable to control same, he tried to alight. In so doing, he smashed into a fence, completely demolishing his front control and badly damaging the front spars on both planes. He suffered a severe cut in the ankle and a bruised shoulder. He made no more flights during the day, but stated he would be out next day if his machine could be repaired in time. Curtiss in alighting in front of the stand came very near having a similar accident. He was able, however, to check his machine by jumping out, so that only the front elevator was damaged. This was repaired in a few minutes. Mars was the fea ture of the day in his 4-cylinder 25 h. p. machine. He succeeded in tying Curtiss' new world's record for quick start—5 4/5 seconds.

His distance was 171 ft. Curtiss then tried to lower this record, but couldn't even tie the same, his time being 6 seconds. Curtiss and Mars circled the course twice, both in air at the same time. Mars just simply had the crowd wild. They applauded every little thing he did.

mars lands on automobile.

On the 10th there was wind and a light rain. Curtiss and Mars made only short flights. In the last one Mars was flying along the track when a gust of wind from between the buildings hit the machine, which swerved and descended at an acute angle. One wing crashed down on the leather top of an automobile in which were some women, and the machine was badly damaged. Mars suffered some severe bruises. Earlier in the day Curtiss had to jump out of his machine and was dragged 30 ft. to avoid crashing into a fence.

Mr. Clarence Phillips, a friend of your correspondent, made a flight with Curtiss the last event of the evening. There is talk of extending the meet two days—roth and nth. The attendance has averaged something over 8,000. All distances were measured by your correspondent, who acted with the judges in all events. The time was taken by Mr. P. White, who is official timer of the New Memphis Jockey Club.

curtiss aviators touring west.

Frank H. Johnson, California Curtiss agent, made some 20 odd short flights at Monterey, Cal.. March 19-20. On the 26th he made several short ones at Salinas, Cal. He narrowly escaped injury when he was caught by a gust of wind and overturned at Oakland, Cal., on April 2.

At Alameda, Cal., on April 5, while making a flight. Johnson landed in the mud and water off Alameda Beach.

His shoulders and hand were wrenched by the fall and he sustained a cut on his temple. The machine was damaged. A boy who gave an exhibition of gliding was also injured. A balloon ascent was another feature of the show.

Charles K. Hamilton made three good flights of from 7 to ir minutes at Tacoma, Wash., on March 20.

The Portland Aeronautical Club, of which E. H. Wemme, agent for Curtiss aeroplanes is president, has stirred up great enthusiasm in that city. Since Hamilton's flights the first part of March, the town has become virtually alive with all kinds of aero inventions and so-called improvements in aeroplanes. Two aeroplanes are nearly completed, and many models. Seventy thousand people saw the flights, the majority of whom saw them from beyond the gates, and the club lost a little over $2,000. If there had been any profits, it was planned to give them to some charitable institution or put them to the betterment of roads. Truly, this object is one which may well be followed in the future.

description of aeroplane.

Each plane is 33 ft. spread, .St<2

ft.

front

to rear, spaced 5^ ft. apart. The finest grade of unbleached cambric treated with a special rubber varnish is used throughout. The ribs of the main plane are of white ash •5a in. square and spaced 15 in. apart; these have a parabolic curve of 1 in. in 20, the greatest depth being about 18 in. back from the front edge The upright struts are spruce, elliptical in cross section. Each lateral beam is in three sections, held together with a metal sleeve, The front horizontal control, pivoted 12 ft. from front edge of the main plane is double, the curvature being in the same ratio as that of main planes, and measures 6 f t. spread by 2 ft. in length, surfaces spaced 2 feet apart This control is balanced off center and is operated by a push rod which is pivoted to the steering wheel, pushing out steers down, and vice versa.

A double horizontal plane spaced 3 ft. apart measuring 6 ft spread by 3 ft. long is placed

11 ft. back of main plane. Between these surfaces is placed the vertical rudder which is 2^ ft. by 3 ft.; this is connected to the steering -wheel by flexible cable wires.

The lateral balance is by wing tips G ft.wide and 2i ft. long. These are placed half way between the main planes and hinged at the tront edge to the two outermost front struts,at both ends of the plane. Cables run from these tips along the upper and lower main surfaces to the back of the aviator's seat. This back is so arranged that it acts as a rest for the aviator and at the same time every movement to the left or right operates the wing tops. If the machine tips to the left the aviator leans to the opposite side, which is a very natural movement. All planes are braced together by piano wire and make a very rigid structure. The planes are set on a 3-wheel chassis and skids. The wheels are 20 in. in diameter and are specially built and equipped with aeronautic tires. The front wheel springing up under the machine automatically when it leaves the ground, leaves it land on the two skids, which are spread 6j/> ft. apart.

The power plant is a 30 h. p. water-cooled motor, which weighs only 125 lbs. and ignition by Eisemann magnets. This motor turns a 6t4 ft. diameter, 5 ft. pitch propeller, at 1,200 to r,_(00 r. p. m., producing a thrust of 225 lbs. to 240 lbs. The propeller is of laminated spruce and mahogany and formed to a true screw.

The motor is cooled by water which is forced to an El Arco radiator by an aluminum pump. The spark advances and throttle levers are placed near the steering wheel. An oil gun is also placed on the left of the aviator, this is to be used in case of emergency.

The whole machine weighs about 600 lb>. without the aviator and lias a total supporting surface of 400 sq. ft.

The 25 h. p. Curtiss aeroplane has been able to carry a passenger. R. O. Rubel, Jr., of Louisville, Ky., was the first to be carried on this powered machine, making three flights of about a mile each over Keuka Lake.

Rockford (111.) Has Aeroplane.

E. K. Barnes and H. H. Havens, both of Rockford, 111., have completed a biplane which closely resembles the Curtiss. The front rud der is a single horizontal plane, with horizontal tail the same. It has a single surface rear rudder. The auxiliary planes are attached to the two outer rear struts. The rudder is controlled with a strut handle in place of a wheel. Steering up or down is by pushing in or out on this bar which is attached to a pivoted upright.

The main planes spread 29 ft. 41:: in. and 4 ft. 6 in. front to rear, placed the same distance apart. The greatest depth of the curve is sJ/2 in., 1 ft. back from the leading edge. The propeller is 6 ft. laminated spruce. A Buick motor will be used in its trial. Ignition by Simms special aero magneto, and a Smith automatic starter, the latter a Rockford product.

MESSRS. Eton and Twining have completed a monoplane measuring 25 by 25 ft., the surface, including tips, double covered, contains 220 sq. ft. The wings are set at a slight dihedral angle. Later equilibrium will be obtained by planes at the sides of the main surface, sliding on steel tubes, being extensions of the main cross beams, operated by hand wheel. Fore and aft control is by a sliding rear horizontal rudder of 40 sq. ft. surface, operated by pushing the hand wheel backward or forward. Lateral control is by a double rear vertical rudder of 10 sq. ft., operated by foot control. The machine is mounted on a combination of skids and wheels.

Power plant consists of a 40 h. p. Mercedes engine weighing 240 lbs., driving a propeller 6 ft. diameter, 6 ft. pitch.

Ernest Ohrt, a young member of the San Francisco Aero Club, now holds the club record for height, towed flight and gliding. The club has its aerodrome located on the sand dunes near the ocean.

The Pacific Aero Club has formulated plans for their aircraft exhibition, scheduled for the first part of May. Entries arc desired from manufacturers of all kinds of aero supplies. For information address C. T. Shaffer, 302 Holyoke Street, San Francisco.

At a recent meeting of the club held in the Palace Hotel, an interesting lecture was given by Lieut. Paul Beck, of' the U. S. Signal Corps, on the Relation of Aeronautics to National Defence. Cleve T. Shaffer, the retiring secretary, gave a short talk on the Relation of Aeronautical Progress to the Future Life of Mankind.

The Hudson-O'Brien monoplane met with misfortune, one of the cylinder heads blowing out. The machine has been materially lightened, and the position of the motor changed. Several other machines around the bay are very near completion.

IComing Events ij in Flying I

The Indianapolis Meet.

Arrangements have been made by the Motor Speedway managers. Indianapolis, Inch, with the Aeroplane Exhibition Co., for the "First National Aviation Meet" to be held June 13-T8. The Wright brothers have given their consent to have this an open meeting and entries are desired from all who have machines that fly.

The following events are promised as a part of the program :

For the machine starting with the shortest running distance.

For the start from the shortest distance, regardless of method for rising in the air.

For the machine making a complete circuit of the Speedway track nearest to the ground.

For the machine making the fastest lap of the Speedway regardless of height.

For the machine making the fastest ten miles.

For the machine landing nearest to a given spot. Machine must land within a given area to receive a prize.

For the machine making the slowest lap of the course in the air.

For the machine remaining in flight for the longest time ("duration prize).

Special match races between various contestants.

Special open events between the various aeroplanes.

Handicap events around complete circuits of the course at various distances.

Carrying various numbers of passengers at fast and slow speeds, near the ground and at high altitudes.

Saturday, June 18, last day of Aviation Meet —Special trials for record high flights. Also cross-country flights over the state of Indiana.

In all these events there will be special cash prizes, trophies and medals, with additional bonuses for lowering existing world's records.

The entrance fee shall be $too for each machine entered in these contests. One entrance fee pays for entry in all events.

There will without doubt, be additional events for dirigible craft, but these become of slight minor importance compared to the aviation part of it. Special efforts are being made to have both Orville and Wilbur Wright fly at this meet in exhibition flights.

It is said the cost of this meet will be $05,000. The managers are guaranteeing the Wright brothers $50,000 cash: money prizes to the amount of $25,000 and promises to spend an additional $20,000 promoting the meet.

St. Louis Aviation in October.

At the first special meeting of the whole membership of the Aero Club of St. Louis ever called, -jo odd members voted March 29 to hold a free aviation tournament, from October 5 to 15, just preceding the international balloon race. All of $20,000 needed for this public exhibition is assured. $8,000 being actually subscribed.

It is expected that the club will secure from three to six aviators who have already been successful with aeroplanes that fly. No contracts will be made for the mere appearance of famous aviators in St. Louis. None will be paid who fail to fly. It is not yet known who they will be or what machines they will use. although it is possible Hamilton and Widard and operators of Wright flyers will be among them.

Oregon Inventor Holds "Meet."

The Commercial Club of Sutherlin, Ore., is planning an aviation "meet" of its own for May 17-19. On this date there is expected to be held an exhibition of a new biplane invented by J. W. DePries of that town. Any aviator is asked to compete in contests for which prizes are offered. A working model of the invention is 'now on exhibition at the office of the club. Those interested should address C. T. Colt, manager, Commercial Club.

Exhibition for New York.

Xew York, April 14.—Flying will be seen near New York either the latter end of June or the first of July; so goes a vague rumor. It may be that some of the men interested in the Wright Co. will finance a series of fliyhts.

Arrangements ,have been practically concluded with the Wright Co. for an open exhibition at Atlantic City.

Mineola Aviation Center.

The largest aeroplane shed, so far as known, is being constructed by the Aeronautical Society on its grounds at Mineola, X. Y. It is located 2,000 ft. south of the Old Country Road, adjoining the fair grounds. The length has now been made 150 ft. by 48 ft. in width, 15 ft. high. Six tons of corrugated iron are being used in its construction. Practically all the space has already been applied for. Rental is at the rate of $1 per roo sq. ft. per month This will be done by the end of April at the latest. Several members now have their machines temporarily in nearby sheds and barns and others will begin work on machines as soon as the shed is finished.

The Aero Club of America has two one-machine sheds on its piece of land within a short distance. One of these is already occupied by W. L. Fairchild.

Dr. J. M. Gibbons has the machine of the Thousand Islands Aero Club in his own canvas shed on the grounds and there are still other individuals who have machines in the vicinity.

A large crate or two have arrived at the station addressed to Capt. T. S. Baldwin, the dirigible man. Perhaps it is an aeroplane—who knows ?

THE aero clubs organized in the New-England States will open the balloon season about May I. These clubs, now located at Hartford, Conn.; Pittsfield, North Adams, Springfield. Lowell and Boston; also the clubs at Rutland, Vt., and Manchester. X. H., will use the ascension stations at Pittsfield, Xorth Adams and Springfield. Mass.; Rutland, Yt.. and Manchester, X. H. There are two balloons at Xorth Adams, one at Pittsfield and three at Springfield.

The Aero Club of Xew England will, in co-operation with the Aero Club of Springfield, maintain a caretaker and balloon rigger at Springfield, wdio will take charge of ascensions under auspices of the clubs at all stations. At Springfield the balloons "Massachusetts" and "Springfield," each 56,000 cu. ft., and the "Boston." 35.000 cu. ft., will be used to open the season. Then the two large bailorns will make several flights from the Pittsfield station, which is specially equipped with facilities for supplying the balloon with gas for long-distance trips. A special gas holder has been built for this purpose, and four large storage rooms.

Forty members of the clubs and their friends, including several ladies, have already booked for flights, and a number from Xew York will use the Springfield station. • There will be four skilled pilots available at all times, and two or three have signified their intention of making the requisite number of Mights to qualify as international pilots this season. Several ascensions will be made for scientific purposes at the time the Halley comet is nearest the earth. An attempt will be made to cross Mt. Washington and win the trophies for long-distance flights, and landing in Canada. One of the largest insurance companies in the United States will -end a representative up in one of the club balloons to ascertain the liability as regards accidents with a view of recommending a form of special insurance for pilots.

The making of three new pilots last vear. II. H. Clayton. J. Walter Flagg and Jay B. Benton, will, with William Van Sleet, at Pittsfield, X. H. Arnold and Dr. R. M. Randall of Xorth Adams and Harold T. Pierpont of Springfield and the writer, give Massachusetts seven pilots, and enable more members of the chilis and their friends to make ascensions.

Probably one of the most interesting ascensions valuable to science will he that of Wil-helm Heinrich, the sightless tenor singer of Dr. Edward Everett Hale's Church, who is also a composer of music and songs and a magazine writer. Mr. Heinrich has been sightless since the age of six. and there is no record of a person thus afflicted making a balloon ascension. I shall use the balloon "Boston" from Springfield early in May. and if conditions are right, try for an elevation of one mile. At this elevation Mi. Heinrichs will compose a song, and on landing give to the world his impressions. Before starting, he will have an opportunity to examine the

balloon and be present during the inflation, through the sense of touch watch all details of preparation.

The ascensions for the observation of Hal-ley's comet will be made on May 6 and 18. The one May 6 in the "Massachusetts" will he at the time the earth is nearest the orbit of the comet, and when it is expected fragments of the comet known as meteorites may be in the air. Passengers in the balloon with me will be Prof. David Todd of Amherst College, Mrs. Todd and Jay B. Benton, city editor of the Boston Transcript. The start will be from Springfield or Pittsfield soon after sunset.

On May 18 the party will compose scientists from some of the other New England colleges, and at this time the earth will pass through the tail of the comet, its head being nearest to the earth—i. e., 12,000,000 miles away.

Through the Aero Club of New England the following balloon trophies have been offered to be competed for during the year 1910:

Automobile Club of Canada, to the pilot starting from a point of latitude not farther ^ north than Poughkeepsie or in the State of Massachusetts and landing on the Island of Montreal.

La Patric Montreal, to the pilot starting from a point of latitude not farther north than Poughkeepsie or in the State of Massa-* chusetts and landing nearest the office of La Patric.

H. Helm Clayton, the "Herald trophy" won by him in 1909, to the pilot landing within 10 miles of Boston Common that starts from a point 100 miles from Boston Common.

H. Helm Clayton, the "Fitchburg trophy" won by him in 1909, to the pilot landing nearer Boston Common than six miles wdio starts from Fitchburg, Mass.

Poland Springs Hotel Co., to the pilot lauding within two miles of the hotel starting from a point in XTe\v Hampshire, Vermont or Massachusetts.

Mount JVashingtou Hotel Co., to the pilot landing on the hotel grounds starting from a point not nearer than Manchester, X. II.. or Rutland. Yt.

Cortlandt P. Bishop, to the pilot making the longest flight in 1910, starting from a point in Xew England.

Certified record of starting and landing must be sent to the secretary of this club, giving name of balloon capacity, time up and down, highest elevation and air line distance. Balloons with experienced pilots can be hired at Springfield. Pittsfield and Xorth Adams and of the Xew England Club.

John Berry continues to talk and to get stories printed in the newspapers to the effect that he is going to ascend to the top of Nit. McKinley in a spherical balloon, propelled and steered by means of propellers. Mr. Berry's own tes's have proved, what might have been known before, that the action of a propeller in a spherical balloon, merely causes the aerostat to rotate, without progress in any direction except that influenced by natural air currents.

Lewis B. Ely Balloon Trophy.

Although others are promised the club by men interested in the advancement of aeronautics in St. Louis, the Lewis B. Ely long distance challenge trophy is at present the only challenge cup or prize open only to members of the Aero Club of St. Louis. This trophy, to be given the aeronaut who holds the club balloon record for distance, is now in the possession of Albert Bond Lambert, who secured it by a voyage of 665 miles, October 15, 1909. The first holder was S. Louis Yon Phul, who won it by his 550-mile voyage in the Centennial balloon race, October 4.

Soon the Aero Club of St. Louis expects to announce standing trophies for the longest, in point of endurance and distance, balloon trip made during the course of each year, to be held by the annual winner until the year following ; cups and cash prizes for aeroplane flights by club members, and perhaps a dirigible balloon trophy.

William F. Assman, who on April 10 made his solo balloon ascension in qualifying for a pilot's license, has ordered a racing balloon from the French-American Balloon Co. He expects to compete in the Peoria race, July 4, and in the national elimination event from Indianapolis, September 17. Mr. Assman will be the seventh pilot of the Aero Club of St. Louis.

H. Eugene Honeywell, director of the French-American Balloon Co., says that interest in ballooning does not lag, but that, on the contrary, the spherical is more popular than ever. Honeywell has received orders during the past two months for four new balloons, and expects to construct three others for western aero clubs taking up the sport before very long.

A. C. A. Recognizes Wright Patent.

gordon bennett meet.

A conference was held on April 9 between Wilbur Wright and Andrew Freedman, representing The Wright Co., and the Aero Club s committee, of Philip T. Dodge, W. W. Miller, L. L. Gillespie, Wm. H. Page and Cortlandt F. Bishop.

At this meeting arrangements were made by which the Aero Club recognizes the Wright patent and will not give its sanction to any open meet where the promoters thereof have not secured a license from The Wright Company.

members had no say.

Xo meeting of the members was held to discuss this most important action—one the like of which has probably never before come up for settlement before any organization in the world and is not likely to again, as far as aeronautics is concerned.

"outlaw" meets may be held.

It does not appear that promoters cannot get up a meet, licensed by The Wright Company, without bothering with any sanction of the A. C. A.

The only loss such "outlaw" meets could suffer would be the non-recognition by the A. C. A. of any new records, but "records are records" whether made under one control or another. However, the A. C. A. can thereafter prevent competitors in outlaw meets from entering their contests.

Of course, any one may give exhibitions by machines not infringing or conduct meets with such machines.

bishop in peculiar position.

President Bishop, of the club, is put in a queer position. One of the organizers of, and alleged to be a stockholder in, the Her-ring-Curtiss Co., against which company an injunction was granted The Wright Company and which has been building machines under a $10,000 bond. Bishop now publicly "refuses to countenance the infringement" of the Wright patent.

The following statement was given out by Wilbur Wright:

It was unanimously decided that every effort should be made to place aviation in this country upon a popular and liberal basis.

The substance of the agreement was that the Aero Chili of America recognizes the rights of the owners of the Wright patents under the decisions of the federal courts and refuses to countenance the infringement of those patents as long as these decisions remain in force.

In the meantime in order to encourage aviation both at home and abroad and in order to permit foreign aviators to take part in aviation contests in this country it was agreed that the Aero Club of America, as the American representative of ihe International Aeronautic Federation, should approve only such public contests as may be licensed by The Wright Company and that The'Wright Company, on the other hand, should encourage the holding of open, meets or contests wherever approved as aforesaid by the Aero Club of America by granting licenses to promoters who make satisfactory arrangements with the company for its compensation for the use of its patents. At such licensed meet any machine of any make nuay participate freely without securing any further license or permit. The details and terms of all meets will be arranged by the committee having in charge the interests of both organizations.

This assures beyond question that the international contests for the trophy won in France last summer will take place in the United States next October and furthermore that numerous aviation exhibitions and contests will be given throughout the country wherever the requirements are adequate and under the auspices of the Aero Club of America.

This announcement does away with any uncertainty regarding the attitude of the Wright Company and of the Aero Club of America toward the future of aviation in the United States and insures the success of aeronautical sport during the coining season.

Under this agreement individual aviators with infringing machines will have nothing to do with the Wright Brothers, unless they chance to be the promoters of the meeting. If an aviator with an infringing machine desires to participate in a meeting he will first ascertain if the meeting" is licensed by the Wrights. He will then ascertain who the promoters are, and will go directly to them to make his arrangement for flying.

Foreign aviators will be perfectly free to enter for the international contest or in an) other sanctioned meeting with any infringing machine they wish to use, but they will be promptly enjoined if they attempt to fly without license or sanction, as was done by Paulhan.

gordon bennett race.

Whoever promotes the Gordon Bennett race will have to secure a license from The Wright Company. Mineola now seems to stand as good a chance as any site for the international meet, providing funds can be secured for the financing thereof. What the Baltimore and Washington Clubs will have to say about this can he guessed. St. Louis is now bidding strongly for it.

bishop sails.

Bishop left for Europe on the 14th of April to lie gone until the first of October. In the meantime the art in this country will have to worry along as best it may tinder its enormous handicap.

Ask Bishop To Resign.

Six very naughty insurgent members of the A. C. A. had the audacity, a few days before the arrangement permitting the holding of the international race without interference was made with The Wright Co., to deliver a letter to Bishop asking that he resign "on the broad-minded premises of justice and patriotism. "For the cause of the better development of aeronautics in America, we ask you to waive personal prejudice and to step aside." to ''restore public confidence in the Aero Club of America."

The letter called attention to the necessity for prompt action in regard to the international race, for the foreigners have displayed no intention of coming for fear of possible legal bars to be erected by the Wrights; to the fact that the date has been fixed so late in the year when calm days are infrequent: that six months have passed since Curtiss won the cup without the club's taking any steps to obtain immunity from the Wrights in order to assure foreign contestants; that Bishop spends the greater part of the year abroad; that the dilatory tactics practiced have caused severe criticisms by various cities that want the race; for shifting the blame in the newspapers on the Wrights for the alleged inability to secure foreign entries.

Air. Bishop has not resigned—as yet. He told the newspaper men, it is alleged, that he did not bother reading letters such as this from indignant members—that his secretary opens the mail and throws epistles of this ilk in the waste basket. The insurgent members claim that too many chances for the betterment of the club figuratively meet a similar fate.

At any rate, a number of members who said they could not let their names be known for fear of the presidential influence, took occasion to express coincident views the day the letter was made public. Then, too, there has recently entered into the club some new blood from which a more hopeful condition is expected by these rebellious, bold and bad buccaneers. "And not only that"—but certain suits are still pending.

It appears as though, some months ago, irrangements might have been made with the Wrights in regard to the international meet 'tself without the question of any percentage entering into the matter. In the published statements of Mr. Wright no mention was at that time made of expecting financial consideration. If this is so, the dilatory methods of the A. C. A. are open to criticism.

af.ro club men might it ave liougttt wright patent three years ago.

About three years ago prominent men in the club allowed the Wright patent to slip through their hands. A fund was partly raised, something like $50,000, out of a suggested figure of $100,000.

"We were approached by a committee of the Aero Club of America, which wanted to buy our patents," said Wilbur Wright.

"The offer looked big to us then and we might have accepted it, but the Aero Club committee allowed the matter to drag along until we put the question squarely up to them. We never received a reply, so we went ahead and developed our invention ourselves. But if a very small part of the money that has been spent on the encouragement of aviation since our invention was patented had been given to us, the invention would now be free to the world.

"We have demonstrated the practicability of our machine for military and sporting purposes/" We have proved that we knew what we were doing, and that we did the right thing unT^ right way. Ours was the first heavier-thau-air machine that ever flew under its/own power. My brother and 1 now purpose enjoying the fruits of our labor."

Washington Club Sends Ultimatum To A. C. A.

j Washington, April 11.—At a meeting of /the Washington-Baltimore Aviation Commit-[tee held here to-day a resolution was adopted to compel the Aero Club of America to take immediate action in completing the plans for the international aviation meet of 1910, which will be held in this country. The text of the I resolution was as follsws :

"Resolved, That the Washington-Baltimore Aviation Committee withdraw as a candidate "-for the international aviation meet of 1910 unless the time and place he decided upon by the Aero Club of America within 10 days from this date and assurance be given by them of the participation by a sufficient number of foreign aviators to make the meet a success."

Dr. A. F. Zalnn, secretary of the committee, sent a telegram to the Aero Club of America notifying the club of the action taken at the meeting and transmitting the text of the resolution adopted.

It is a foregone conclusion, however, that the event will not approach in magnitude that of last year.

Herring-Curtiss Co. in Bankruptcy.

The Bank of Ilammondsport and two other creditors of the Herring-Curtiss Co. have filed a petition in involuntary bankruptcy and a Receiver was appointed on April 2. A number of the creditors of the company have issued a letter asking the others to co-operate in the proceedings.

good outlook.

The letter issued contains the statement: "It is believed that' not only can the claims he paid in full, but also that there is an excellent opportunity for a continuation of the business whereby the creditors will be benefited."

Wright-Curtiss Suit Appealed.

Inasmuch as both parties to the Wright-Curtiss action wanted to go to the Court of Appeals with the preliminary injunction matter, there was no argument at the rehearing in March, but all agreed that additional evidence and arguments should go into the record in order that an appeal might be taken at once. Case on appeal will probably be heard the latter part of May.

J. Edgar Bull has been retained with Emerson R. Xewell in behalf of the defendant.

Auto-Aero Show at Buffalo.

Buffalo, March 26.—Aero divisions to shows of all kinds are dc ricjcitr nowadays. The sportsmen's show, running from the 21st to the 30th. has three full-sized flying machines, an aeronautical engine exhibit, and five large models loaned by members of the Buffalo Aero Club. Dr. George Francis Myers is showing his circular biplane and an ornithopter which, it is claimed, has lifted a foot off the ground. The Elbridge Engine Co., of Rochester, have one of their featherweight aero engines, water cooled. Among the models is that of R. W. Magruder, fully equipped with a 1 horse power motor.

Hermann A. Brunn, a Buffalo body builder who built the touring body on Mrs. Leslie Carter's car, is making arrangements to build one or more aeroplanes this coming summer.

Death of Thomas F. Walsh.

Mr. Thomas F. Walsh, president of the Aero Club of Washington, who had been seriously ill since last December, died at his residence on Friday, April 8, of heart failure, brought on by pneumonia.

Mr. Walsh had been unanimously elected president of the club two years in succession since its foundation, and did much to increase the membership and usefulness of that organization. He was also unanimously elected chairman of the Washington-Baltimore Aviation Committee, and labored earnestly to secure and prepare for the international aviation meet of tqio. His death is a loss keenly felt by all those interested in the promotion of aeronautics in America.

Mr. Walsh obtained great wealth through mining. He was one of the national commissioners to the Paris Exposition in 1900. He was a member of the Washington Academy of Sciences, of the National Geographic Society, of the American Association of Mining Engineers. He served a term as president of the National Irrigation Association.

He was closely associated with Washington business enterprises. Two large office buildings were erected by him. In addition, he was the owner of the property, formerly known as the Oxford Hotel, besides a large amount of other real estate. He was a member of the executive committee of the Washington Board of Trade.

Fie was a member of the Denver Club, of the Metropolitan and Cosmos Clubs, in Wash-

ington, and of the Metropolitan Club in New York. He also belonged to the Travelers' Club of London, American Political Life Association, El Paso Club, Automobile Club of America, Automobile Club de France, the Pilgrims of London, the Pilgrims of New York and others.

IIis engine stopped on one occasion and he landed in the sea, but was towed ashore with out trouble. On April 2 the machine fell in the water. It was 17 minutes before anyone got to Le Blon. lie seemed to be only slightly bruised and his death has been directly attributed to drowning.

Whether the Gnome motor gave out or not is not known. Bleriot has declared against the big 7-cyl. rotary 50 h. p. motor on a little machine like the "XL" Le Blon was famous as a racing auto driver. At the Doncaster meet last year he did some good dying.

Balloon Accidents.

An extraordinary balloon accident occurred in Germany cm April 3 involving Ihe loss of three lives. The balloon was started from Stettin in a gale, but in ascending it collided with telegraph wires and then with a factory. These impacts almost tore the car from the gas bag. The balloon was swept out to sea. lauding in the Bailie Sea near llerrenbad a few hours later. The balloon carried Dr. W. II. W. Delbrnck, member of the Ueiehstag, and Messrs. Semmelhardt. Bcndtihn and lleim.

In the collision all were more1 or less injured. The valve cord was broken and the rip cord was used as the balloon dropped heavily to the water.

All were exhausted and three sank, only Sinn melhardt being rescued. One body has not yet been recovered.

tin April 4 Prof. R. Abegg and two companions left in a balloon from Rreslau. In the landing, after two had gotten out, a gust of wind dragged the balloon before Prof. Abegg could get out. Ik-was thrown out and died from his injuries.

Aeronautics' Permanent Aeronautical EXPOSITION

INFORMATION BUREAU.

On May i AERONAUTICS will remove its offices to new and larger quarters in the building just completed at No. 244-252 West Fifty fourth Street, just off Broadway.

PERMANENT AERO EXPOSITION.

Additional space has been secured for our Permanent Exposition and Bureau of Information which we will inaugurate on May 1.

It is our intention to have on exhibition everything pertaining to aeronautics manufactured in this country, at least. Our daily visitors can then see the various products and make their selection without visiting the various factories. This will prove a great boon to the purchaser and maker alike.

This exposition is open to any manufacturer, whether an advertiser or not. It will serve the manufacturer as a New York office and salesroom. It will serve the prospective buyer as an information bureau, where he can see samples of what he wants and secure all the information available in regard to each product.

The building is fireproof, extremely well lighted and convenient to all lines of transportation. Our office will be more than ever the national headquarters for anything aeronautic.

This is the first time that a bureau of aeronautical supplies has been established. A full supply of data on each particular exhibit will be constantly on hand, and it will not be necessary for a prospect to let his name be known to a single maker, and at the same time he can view the products of every factory in the line in the country.

TO MANUFACTURERS.

We want to hear from you relative to this Exposition. You cannot afford not to have an exhibit. We will be glad to send you further particulars and to aid in any way possible.

EXHIBITORS.

While very little time has been available to arrange for exhibits, one can be assured that the line will be complete. Owing to the short notice, many firms cannot have samples ready in time for the opening. Engine builders are all more than busy with orders. The following firms will be definitely represented:

Hartford Rubber Works Co., Tires. Victor L. Bkunzel, Varnish.

WittemAnn Bros., Gliders and Supplies. El. Arco Radiator Co., Radiators.

Requests for space should be addressed to the secretary, 240 Michigan Ave.

AERO CLUB OF AMERICA BANQUET.

New York, March 25.—The banquet hall of the St. Regis was filled last night with members of the Aero Club of America and their guests on the occasion of the fourth annual dinner.

Those seated at the guests' table were: J. C. McCoy, Com. E. C. Benedict, F. ^. Doubleday, Prof. A. Lawrence Rotch, William M. Page, Cortlandt F. Bishop, Hon. J. Sloat Fassett, Gen. James Allen, Glenn H. Curtiss, Charles J. Glidden, Colgate Hoyt and Rennold Wolf. On the table were the famous trophies won by Curtiss and Mix and overhead were hung models illustrating the three types of aerial locomotion.

Following the precedent established last year, three of the speakers studiously avoided any very great mention of aeronautics for fear of displaying, perhaps, their lack of knowledge on the subject. Professor Rotch and Brigadier-General James Allen, Chief Signal Officer of the Army, however, spoke solely on aeronautics.

In introducing the speakers, President Bishop called attention to the records made in winning the two Gordon Bennett cups on their first offering and the fact that the government owned the Baldwin dirigible and an aeroplane. The dirigible he characterized as too small and "not now available" and the Wright machine "not the latest development."

FASSETT FOR AMERICAN SUPREMACY AT ANY COST.

Hon. J. Sloat Fassett, M. C. .expressed himself in glowing language as being heartily in favor of providing the United States with ample means at any time for maintaining supremacy in any line. He frankly denied knowing anything about the attitude of Congress in regard to aeronautical appropriations for matters of this nature are kept rather under cover since the Langley fund, he said. "Congress has spasms of economy. You must catch it between spasms." Pleading ignorance in graceful terms of future possibilities of flying, be risked, on the other hand, prophesying the conquest of the air would work greater changes than had any of the great inventions of the past. There will come into question

future laws, customs, rights of owners of land, etc.

BISHOP'S LAWYER URGES CONDEMNATION UK WRIGHT PATENTS.

William M. Page, Bishop's attorney in the recent suits brought against him by the rebellious members of the club, was second on the list. After distributing verbal bouquets to each of his associates at the table of honor, he rather startled his hearers when he suggested that Congress pass a law so that any patent which "ran through the warp and woof of prosperity be condemned." If the government wanted his house and land for any purpose it would condemn the property and pay him its reasonable value. He would apply the same plan to patents. One to fi.ve millions of dollars he would offer the Wrights as a reward for their achievements and "throw open the world to aerial navigation." The present situation he called the "menace of the Wrights."

GENERAL ALLEN'S REMARKS.

First-class powers, excepting the United States, said General Allen, are providing themselves with aerial fleets, but he expressed no alarm at the present apparent inactivity of Uncle Sam in matters aerial. He felt sure that our government would in proper time be a liberal purchaser of aeronautic material and vehicles and take due eare of the country. In comparison, he referred to the great work of Germany.

PROF. A. LAWRENCE ROTCH.

Prof. A. Lawrence Rotch, director of Blue Hill Observatory, at Roston, followed General Allen with a reference to the connection of Roston with aerology. Two of her illustrious citizens were identified with the art; Franklin and Dr. Jeffries, who crossed the English Channel in a balloon. Harvard and the Massachusetts Institute of Technology will soon, he said, have regular courses in aeronautics. Then he told of the forming of the Permanent International Commission for Scientific Aeronautics in 1896, two years after he anticipated some of the Commission's work at his Blue Hill Station. In the future he prophesied maps of the air currents.

RENNOLD WOLF.

Wolf proved to be the wit of the evening. With the utmost naivety he charged Bishop with "enticing a maiden. In matters aeronautic I am a virgin. I have no warp in my plane and on charges of ethereal misconduct

can prove a complete alibi." The only connection he ever had with such things, he said, was during his boyhood, when he was hit on the toe by the sandbag of a professional aeronaut. 'The Romeo of the future will not climb to a dinky balcony, but will fly his monoplane into Juliet's chamber through the window and alight on the bedpost. Camille will be rescued by a triplane and carried away to a drier climate and save both her health and reputation." In conclusion he decided he would be content to continue his study of aeronautics through a correspondence school and at dinners of the Aero Club.

Pictures were shown of the Rheims and Los Angeles flights and Bleriot crossing the Channel.

The Wrights were conspicuous for their absence. The new club book states that they have been honored with the license of the Aero Club of America to fly.

The new rooms of the Aero Club of America in the United Engineering Societies Building, 29 West 39th St., were opened for the inspection of members and guests on Wednesday evening, April 13, at 8.30 o'clock. During the evening moving pictures illustrating the recent progress in the science of aviation were shown in the auditorium of the building.

The American Aeronautical Society, which is claimed to be the oldest aeronautical organization in the United States, organized in 1887, has gone through some changes, but in main it has remained the same, that of scientific investigation.

Recently it has been decided to extend its scope, to increase its power by an increase in membership and secure rights and protection, legal, financial, political and co-operative.

1st. Legal rights will he secured by a combined effort to protect the ideas and inventions aiainst grasping individuals or corporations by a well sustained legal opposition to any usurpations by monopoly tending to suppress legitimate progress and development of aerial navigation.

2nd. Financial advantages will be secured to the members irrespective of invention for the monthly contributions toward enabling members with ideas to secure full and complete legal protection and assistance, financial opportunities for exploiting their invention. The consideration being a participation in the result so obtained.

3rd. Political action has been shown necessary for the purpose of obtaining substantial governmental aid and full investigation of various ideas, which result will be obtained by a large and active membership.

4th. Co-operative union of the individual abilities into one compact body will bring about a mutually permissible use of the varied devices giving the greatest publicity and cheapest thorough workout of the ideas in various combinations, enabling the members to obtain the royalties rightly due themi, and an easily attainable' construction, the most highly developed and safest aircraft at popular cost, yet fully protected by registration licences and mutual watchfulness.

An Aero Club has been formed at Tufts College, Mass. Edwin P. Bugbee is president, Geoffrey W. Talbot secretary-treasurer. Prof. Harry G. Chase has offered to pay for a glider.

The Aeronautical Society is now the new

name of The Aeronautic Society. At a meeting on April 7 a new constitution and by-laws were adopted to accommodate circumstances which have come up which could not be foreseen when the society was first organized. The society was formed originally, as now, under the stock corporation law, although it is not a body for the conduct of any business. The idea was novel, and a perfect organization was found to have not quite been realized under the first set of by-laws. Because of the reincorporation, it was necessary to make some change in the name, and the simplest method was adopted; after a great deal of discussion, that of adding "al" to the word "aeronautic." It is believed that the new set of by-laws, which were framed by Lawyer Thomas A. Hill, are very nearly perfect, and that for every condition likely to arise provision has been made.

biggest aero shed.

At the same meeting bonds to the extent of $1,500 were ordered issued to cover the building of the shed at Mineola.

On March 31 the society listened to a most interesting and instructive illustrated address by Edward W. Smith of Germantown, Pa., on "Stability," and a humorous story by A. D. Lee on "An Aeroplane Flight in Arizona."

William J. Hammer delivered a lecture upon "Selenium and Its Industrial Application" on April 14. This was on similar lines to the one delivered recently before the Engineering Society of Stevens Institute. It was profusely illustrated by lantern slides, and types of selenium cells and other apparatus. Selenium is a by-product from the manufacture of sulphuric acid from iron pyrites, and when employed in the selenium cell is an absolute non-conductor of electricity in the dark, but becomes a conductor when light falls upon it. It was explained how the selenium cell may he employed in speaking over a beam of light, controlling electric and other motors and dynamos, transmitting pictures over wires, firing guns by a shaft of light, signaling to aeroplanes and balloons, etc.

The Aero Club of New England has voted to buy an aeroplane this summer and to hold an aviation meet. At the last banquet of the season, held April 4, the following committee was appointed to arrange for the purchase of the machine and likewise for the meet: Henry Howard, chairman of the aeroplane committee of the club; A. R. Shrigley. secretary of the club, and Dr. F. L. D. Rust. The only stipulation which the club made regarding the purchase of the aeroplane is that it must be capable of carrying two passengers.

Chairman Howard of the committee has just returned from a visit to the factory of the Wright Brothers at Dayton, O.. where he was permitted to inspect the work being done there. He told the club about his meeting with the distinguished aviators and of his

efforts to get them to give an exhibition in Boston the coming summer. Although they disclaimed any desire to commercialize aero-planing, they refused to come, he said, unless $50,000 was guaranteed them.

In view of their disputes over patents with other inventors, the subject of aviation contests was broached. To these the Wrights did not object, said Mr. Howard, provided they were held not as a professional meet, but as an amateur event.

Among the speakers were Charles J. Glid-den, W. Starling Burgess, A. M. Herring, Prof. Gaetano Lanza of Technology, Prof. William H. Pickering and Prof. A. L. Rotch of Harvard, Xorman Prince, J. H. McAlman, James Means, J. Fortescue and A. A. Merrill.

.Mr. Herring and Professor Picketing told of a number of experiments which they have been making with regard to producing equilibrium in aeroplanes.

The Aero Club of St. Louis has added about 100 members in the past month, principally from advertising circulars sent out to members of other clubs and automobile owners by Secretary Noel.

The Aero Club of St. Louis will conduct a free aeroplane exhibition, October 6 to 15, which will be followed, on October 17, by the international balloon race. Xo aviators have been engaged, so far, for the exhibition ; but the club expects to have six; or eight aeroplanes with successful operators.

The Aeronautic Experiment Association of St. Louis has 12 members whose machines will be completed before the middle of May. and nearly all will be ready about May 1. The association has now about 40 members and the roll increases at each of the bi-monthly meetings. The latter are well altended, ,^2 members being present at the last 011 March 30.

Water-cooled cylinders are cast en bloc, which is the only way to get compactness so much sought after, with exhaust valves on one side and the intake manifold cast in cylinder wall on the opposite side, doing away with many joints which cause so much annoyance. Xo asbestos packing is used. The gases coming in on the opposite side of the exhaust will always have a tendency to thoroughly clean the cylinders. Aluminum caps cover the' valve ports, which are especially large, giving easy access to valves should they nee. reseating. 'The crank case is of aluminum, carry ing the crank shaft on two large lless-l'.right ball bearings: the crank is cut out of solid bar of high carbon steel; bearings are ground to size: a small gear pump forces at all times perfect lubrication to all bearings. Ignition is by a timer and high-tension magneto. A special light radiator of ample size is furnished with motor to take care of cooling system. An aluminum fan flywheel '2'j. in. in diameter helps to keep the motor cool. The company furnishes also different sizes of laminated spruce and white wood propellers, and radiators.

El Areo radiators have honeycomb so.ua re-cell tubes with wide vertical water passages, the tubes being spaced *i apart on centres. The const ruction of El Areo tubes avoids the use of spacing strips to form the water passages, usual in stpiarc-cell radiators, the water spaces being formed by

offsets in the metal of the tubes so that the edges of the tubes present the minimum of resistance to the air. and the tubes can therefore be assembled in the most compact manner possible. These radiators are tested under lbs. air pressure, and are guaranteed against defects of workmanship and materials and against clogging up.

These radiators are guaranteed to cool motors of indicated horse powers when used in aeroplanes when in flight. Motors used in dirigibles should have radiators rated for motors of 5u per cent, greater horse power.

The principle of Palmer construction, followed in the aeroplane tire, has kept a nre-einiueiit place in the field of light and durable tires. The greatest speed recordls in bicycle racing have been won on Palmer bicycle tires. In fad, Ihore has been no competition in this line of equipment. Again, the Palmer sulky tire, for over 1 5 years, has been the standard required by the maniifac furors and drivers of sulkies.

This very great popularity testifies to the reliable type of tire chosen for the unusual demands of the aeroplane. The Palmer construction is distinguished for its fasl and easy riding quali ties and by its lightness.

The Palmer aeroplane tire is about l!5 per cent lighter than any of the single tube tires of the same size and about fill per cent lighter than double tube tires. Every ounce of weight that will be a drawback to the efficient use of the plane is (Eliminated. There is no dniid weight or holding back in getting away from the ground. The standard size of the tire is UO by 'iVi in., and the weight is '2 lb. 5 oz.

The tire is built up of four plies woven so that the threads of one plj are at an angle of 45 deg. to those of another. Thus there is a seamless, endless, spiral tube, with each Ihrcai embedded separately in pure rubber. This sub stitution for interwoven fabric gives the Palmer aeroplane lire the greatest amount of buoyancy and resilience. In addition, an unusual cptan tity of pure rubber combines all the pieces closely so' they will not separate, and prevents friction between the threads. This assures dura bility and long life.

Lightest reliable motors on the market Finest mechanical construction

In fact, the Palmer tire is not an experiment.

It lias been the subject of very careful test.

It is 1 lie result of long experience and it has proved its' reliability in actual use.

The Palmer tire is the regular equipment if the Herring-Curtiss planes with which Mr. (lleiin II. Curtiss won the International Cup last summer al lMteims. Prance, and established further claim to the title at the January aviation meet at Los, Angeles, California.

The 15. F. Goodrich Co. has made careful preparation so that it is able to make the tires according to the specifications of manufacturers and of individual aeronauts who are experimenting with their own planes.

.NEW WHITEHEAD Ml >T< lit.

Among the latest assets of the art is the new Whitehead motor, built by Gustav Whitehead, who is quite well known as a builder of special engines. A partnership has been formed with George A. Lawrence, a well-known aero enthusiast and experimenter. They have already delivered their lirst motor, one of To h. p., to C. & A. Wittemann. The Wittemann brothers have adopted the Whitehead motor exclusively and orders are now being put through for 'two more. This first motor is to be used on an aeroplane of their own design.

.Messrs Whitehead and Lawrence are making two sizes. 40 and 7-r> h. p.. the former weighing 145 lbs. and the other 200 lbs., including the four gasoline vaporizers, shaft coupling, timer, wiring and plugs. The motors develop their rated power at l.ooo r. p. m. but can readily be run at higher speed. Under most favorable conditions 55 and N7 I), h. p. respectively are promised.

A feature of this new '2-eyele engine is the absence of carbureter, all four cylinders being fed by individual injectors. Each cylinder has eight exhaust ports. Phosphor bearings are used in place of balls. Thrust bearing is located on inside of crank case.

THE NEW EISEMANN' AUTOMATIC MAIiNETO.

It. has become customary in many instances to entirely dispense witli means for varying the time of the spark The ignition mechanism is set for a lixed spark—generally 17 deg. to '20 d^g. advance— and ignition will always take place at the sanm time, whether the motor is running slowly or at its maximum speed. How faulty this system is and what disadvantages it enlails is obvious without a very extended demonstration. The motor develops its maximum power only at 40 deg. to 4S deg. advance. In fact, a motor of medium size develops up to <> Ii. p. more power with 15 deg. ignition advance than with 2d- deg., and that without a corresponding increase in fuel consuniD-tion. The reason for this is that in the case of "late ignition, combustion in the cylinder is completed only long after (he dead center is passed, when the combust ion space has ben greatly enlarged by the downward motion of the piston, whereby the effect of the explosion is appreciably reduced. A portion of the combustible mixture therefore passes unused into the exhaust, so that the fuel is used in a very wasteful manner.

At slow speed ignition at 2D deg. advance is loo early, and the explosive force of the gases is I hen expended on an upward moving piston. This results in unpleasant knocking of the motor and premature destruction of the bearings.

It is —

(1) FASTEST—No dragging nor holding back, in the running start from the ground.

(2) LIGHTEST—S t a n d a r d

A further very serious disadvantage of fixed ignition is the fact that in starting the motor with 17 deg. to I'd deg. advance a back Are is 'ilmost unavoidable.

Eisemann o4utomatically Timing cTWagneto

The Eisemann Magneto Co. is this year placing upon the market a magneto whose armature shafl is provided with a small hall governor. The governor weights draw closer together or move apart, according to the speed of the motor, and in this manner effect the proper timing of the spark from the late ignition to maximum ignition advance. The arrangement is very well thought out, and the construction is considered nighly successful in technical circles. Without entering into the manifold advantages, it may be here pointed out that with this timing arrangement the spark always occurs at the moment of the most ad\anr tageous position of the armature, so that the cranking of the motor is accomplished much easier than formerly, and exactly as strong a spark is produced at full retard as at full advance. As the timing of the ignition is varied in proportion to the speed of the motor and the spark always occurs at the most favorable time, the fuel is used to the very best advantage.

AVIATORS, ATTENTION!

A TIMELY WORD ABOUT MOTORS

MT[ What you want is A Real Aeronautic Motor, light and yet ^1 strong, simple, and above all reliable. A motor, moreover, that the average mechanic can understand and operate.

What you do not want is a combination motor cycle, or modified automobile, engine. Lightness in these is secured only by the sacrifice of strength and efficiency; and yet either type is unduly heavy. We have tried both, and we know. Before you invest, it will be worth your while to write us, and hear what we have to say.

At an expense of several years experimenting, and many thousands of dollars outlay, we have at last perfected a high grade, water cooled, four cycle, gasoline engine for aeronautic work.

By special method of construction, upon which we are securing patents, these motors are much stronger than the ordinary makes, and at the same time very much lighter.

The 40 horsepower engine weighs 3 pounds per horsepower, and the 80 horsepower only 2h pounds per horsepower:—about one-half the weight per horsepower of any other adequately water cooled engine. The weight as also the quality of each engine is guaranteed.

These motors are not of freakish construction, either in the number of cylinders, or in any other respect. They are of the regular opposed type, similar to the famous Darracq aeronautic engine with which Santos Dumont's machines are equipped, conceded by gas engineers to be the smoothest running, and nearest vibrationless type.

A scarcely less important feature is the fact that our motors are silenced (not muffled), which feature is secured without loss of power. They are, in fact, the only silent motors yet devised for aeronautic work.
