JANUARY g, 1909. ** Antoinette-** Monoplane built and engined by the Soc. Antoinette. It has, like the " Bleriot No. 9," a particularly light, Santos Dumont's " La Demoiselle.** Besides being the smallest machine at the show," " La Demoiselle " hangs aloft by a wire like a toy butterfly so that few of the visi- tors noticed its exist- ence. It is a mono- plane having a twin- cylinder engine mounted above the The engine two-bladed speedy appearance, and is not unlike a huge dragon-fly when viewed from above. The long V-section girder frame, resembling a racing skiff, enhances its sporting effect, and suggests that the type might become very popular if ultimately proved to be successful. Part of the frame is filled in by the condenser-tubes belonging to the Antoinette installation, as described elsewhere. At the rear is the rudder and the elevator; both are small triangular surfaces, and the former is placed immediately above the latter. They also both form extensions of fixed triangular planes forming a cross-tail. " Pischoff-Koechlin." Monoplane having a car built like a boat, and with the pilot's seat well forward immediately between the main wings. In front is a divided elevator, and there is another behind in addition to a divided rudder. The controlling apparatus was not assembled, nor was anyone in evidence on the stand to explain what would be employed. Immediately behind the main wings are two wooden propellers, driven by chains from a twin-cylinder (opposed) horizontal engine. ® wings. drives a tractor-screw and the aviator sits beneath on a light saddle. The spread of the wings is only about 5 metres, and their surface only about 9 sq. metres. The total weight is only 67 kilogs., so that it can be very5total readily handled by one man; it has already achieved some short flights.

IT is a very singular fact that a propeller is regarded by the uninitiated as the simplest possible kind of apparatus; while, by those who know or try to know the facts, it is looked upon as one of the most puzzling devices in the TABLE OF PROPELLERS AT THE PARIS SALON.

Its study is an education in itself, and an entertaining one to boot, for to read the innumerable different theories on the subject which have been propounded from time to time by various investi- gators of the laws appertaining to the propulsion of ships—for it is, of course, in marine work that the propeller has hitherto found its field of greatest utility —is often divert- ing, to say the very least. Very little is known about the aerial propeller at the present day, and it is very evident that a great deal will have to be found out before the utmost capabilities of aerial engines are turned to the best advantage. It is very certain that some of the propellers on view at the Salon will not be considered as high-class examples of design and workmanship in a few years to come, but then it is also just as obvious that very serious efforts are already being made by different firms to cope with the problem in a fashion that is at once scientific and commercial.
