[[page cut off]] of Directors of the Aero [[page cut off]] rica has decided to hold [[page cut off]] the international Aero- [[page cut off]] St. Louis. That city is, [[page cut off]]aphical point of view, ex-[[page cut off]] ocated, being far removed [[page cut off]] in all directions. [[page cut off]] rities of St. Louis have set [[page cut off]] starting point of the con-[[page cut off]] ion of Forest Park. this [[page cut off]] be inclosed in such a way [[page cut off]] will be no interference with [[page cut off]] of the big bags, and the [[page cut off]] gas will be sufficient for [[page cut off]] ling all the balloons that will [[page cut off]] contest.

According to the information [[page cut off]] by the Weather Bureau dur-[[page cut off]] long period of observations with [[page cut off]] and pilot balloons, the usual wind [[page cut off]] at that season of the year [[page cut off]] upper altitudes proceeds in an [[page cut off]] direction toward this city, [[page cut off]] to the south of the Great Lakes. [[page cut off]] weather is invariably to be ex-[[page cut off]] then, there being usually but [[page cut off]] or four days of rain in the month. [[page cut off]] average temperature at the surface of the earth in October is about [[page cut off]] def C. [[page cut off]] will be recalled that the greatest [[page cut off]] balloon flight ever made in the United States was made from St. Louis [[page cut off]] John Wise, in 1859. He landed in [[page cut off]] County, this State. The Aero Club of America announces [[page cut off]] will be furnished free of cost to [[page cut off]] contestants for the prize. Special [[page cut off]]can be secured at the hotels, and [[page cut off]] a sufficient number of members of [[page cut off]] clubs belonging to the International [[page cut off]] attend, it will be possible to secure a special rate of fare from this [[page cut off]] to St. Louis and return. The regular fare is $24.25, but in case enough aeronauts attend the contest, it is probable that a rate of about $32 will be made for the round trip. The steamship companies on the lines running from Europe to this country may also make concessions. The Aero Club is at work on an arrangement by means of which the balloons of foreign contestants will be admitted in bond free of duty during their stay in America. Besides the prizes annually offered in the contest, various organizations in St. Louis will offer supplementary prizes for second, third and fourth places, amounting altogether to about $1,000. For those wishing to make trial flights in preparation for the contest, or for those wishing to compete for the Lahm Cup, which will be offered for competition after March 1, 1907, arrangements have been made to supply gas at a specially reduced rate. This applies only to pilot recommended by the Aero Club. The rules of competition for the Lahm Cup will be announced later. [[page cut off]] City [[page cut off]] Dr. Julian P. Thomas, the aeronaut went a long way yesterday in his experiments toward perfecting a mechanism which, he believes, will prove invaluable for airships and aeroplanes. The experiments, which were made entirely on the ground with motive power, were witnessed by thousands of persons, and the West Side, in the neighborhood of 72d street, was almost blocked to traffic for two hours or more. [[page cut off]] just as well as an [[page cut off]] all points of the compass and [[page cut off]]. It proved even more flexible than [[page cut off]] auto. "We got the engines up to a point where the fan moves 65,000 cubic feet of air every minute. That is enough to fill my largest balloon every minute. I believe we will get even more. When we hitched a pair of scales to the back of the [[page cut off]]. [[image: wind wagon]] DR. THOMAS TRYING OUT HIS WIND WAGAON AT BROADWAY AND 72D STREET. Dr. Thomas experimented solely with his wind wagon, or heliocoptere, as it is properly called. The primary object was to test the parts that go on an airship or aeroplane and see how much pulling power could be obtained from the air by a propeller. The experimental wind wagon is a peculiar machine, and Its appearance attracted the crowd more than anything else. As a starter it looks like a tricycle. Two steel bars stick up from the tricycle and two point downward. A shaft runs through the body and a four-bladed steel propeller is fastened at the end. For the first time since Dr. Thomas began his experiments some time ago the engine was in perfect order yesterday, and the shafting and joints were as strong as possible. Heretofore it had been found that it took too much power to turn the propeller rapidly, and the steel parts broke somewhere or other every time. There was not a break of any sort yesterday. The experiment began at the shop in East 79th street, near Second avenue, where the wind agon is stored. Dr. Thomas had four assistants, two expert mechanics, an electrician and an engineer. The wagon was driven down to the East River and back again, the return trip being up in incline. At Third avenue the wagon was turned in the street without any difficulty and then went back to Second avenue. On the trip to the West Side Dr. Thomas tried to run through Central Park, but was stopped by the police, as he towing his automobile, which was against park regulations. Eighty-sixth street was used instead. On the way down Eight avenue the batteries jostled loose, owing to the poor roadbed, and when the wagon reached Dr. Thomas's home, at No. 172 West 72d street, the batteries short-circuited. The batteries from Dr. Thomas's automobile were used. The added weight of the new batteries, as the others were not removed, did not prevent the most successful experiments so far undertaken. Word that a strange and weird machine was being run quickly brought the crowd,[[page cut off]] wagon it pulled seventy-five pounds. I believe that we can attain great speed after we get our momentum." Dr. Thomas expects to make further experiments in a few weeks. The aerial experiments will come later. Last night he went to Hammondsport, N.Y., to test one of the lightest engines ever built in America, made specially for him. Dr. Thomas said that there was only one lighter, it being owned by the United States Government. The engine is a four-cylinder one, and if it answers all tests will be put on the wind wagon. The engine is guaranteed to have 15 horsepower and to weigh less than one hundred pounds. "If the engine proves satisfactory--and the other speed parts are certainly satisfactory--there is no telling how fast an airship will go before this year is ended," the doctor said.
