dietro o destinate a sostituire la coda dell' uccello. L'apparecchio ha dato, a quanto sembra, risultati soddisfacentissimi. Josse Weiss, francese, ha dato al suo apparecchio la forma di un albatro. II generale Baden Powel, che combatte nell' Africa australe contro i boeri, espone tre modelli, uno dei quali e formato da due ali sovrapposte che girano in senso inverso e sono azionate da un motore collocato sopra le due ali, motore che poe ugualmente in moto un timone. Un povero vecchio, Fren Hall, e venuto da Eye, nel Sufolck, a piedi fino a Londra, una distanza di 152 chilometri, per esporre egli stesso il suo modello. Ha portato per quattro giorni il suo apparecchio sotto il braccio. IL RACCOGLITORR. Sun-Journal New York 1 Aprl 1907 FIX ON AERIAL WAR MEASURES ------------ London, April 1.-It was learned to-day that negotiations have been going on among several of the European chancelleries regarding the coming peace conference at The Hague, and that a difference of opinion already exists among the nations relative to limiting or not limiting aerial warfare. At the first peace conference a clause was adopted prohibiting the use of bombs from balloons or airships, but this was allowed to lapse after the second session of the Powers at The Hague. Since then, however, three nations have been signally successful in experiments with balloons. These nations are France, Germany and England. For once, it seems likely that |Upside down note| TURFNOTES physics in the John Hopkins university, and Otto Luyties, a skillful mechanical engineer of Baltimore, hope they have solved the problem in aero navigation upon which Langley failed and which Santo-Dumont has not yet succeeded in unraveling. Prof. Wood is successor to the late Prof. H. A. Rowland, inventor of the famous spectroscope grating machine, known to all physicians and the multiple telegraph system now being introduced in Europe. Of Same Class a Aeroplane. The type of machine upon which Prof. Wood and Mr. Luyties are at work is known as the "helicopter," and it is entirely different from the balloon type and belongs to what is known as the "heavier than air" class of airships now attracting the attention of all who are interested in aerial navigation. It belongs properly to the same class with the aeroplane, which was the subject of extensive experiments by the late Prof. Langley of Washington. The Langley airship, however, has several drawbacks, the most serous of which is the difficulty of making landings because of the extreme high rate of horizontal velocity which is necessary in order to keep up in order that the ship may sustain itself in the air. Steam Engine for Motive Power. In the "helicopte" Wood and Luyties hope to overcome these disadvantages entirely. In the first place, there is no stationary supporting surface, such as is required in the aeroplane, which maintains its position in the air by several pairs of huge wings and the high rate of velocity at which it is drawn. Dr. Wood purposes using a steam engine modeled after those used in the racing automobiles, for motive power. On the ship on which they are now working is an engine weighing about 900 pounds and capable of generating horsepower.
