Designed by Dr. Graham Bell, of the Aeronautical Society of America. Bell (Canadian), Glen Curtis (U.S.), Herring (U.S.), and Burgess (Canadian). It made short flights.] [Illustration: ENGLISH (1909). In 1909 extraordinary claims were made for this machine and great things expected. On a full power trial in its shed it broke loose, and smashed itself against the roof. No recorded outdoor results.] [Illustration: HERRING-BURGESS (1910).] [Illustration: HULBERT (1910). This strange machine built in Switzerland by Dr. Dane Hulbert, achieved several flights. The planes were placed longitudinally instead of in the usual way.] [Illustration: JUNE BUG (1908-09).

AERO ENGINES, ALPHABETICALLY ARRANGED IN ORDER OF COUNTRY OF ORIGIN. ~AUSTRIAN, BELGIAN, BRITISH, FRENCH, GERMAN, ITALIAN, U.S.A.~ ~Note.~--So far as possible this is a complete list of all the aero engines of any importance. Data are confined to what is now being made or actually in use; untested "show novelties" are ignored. In the case of some engines it has for various reasons proved impossible to obtain full data in time for inclusion in this edition. In a general way these lists are confined to aeroplane engines. ~AUSTRIAN.~ ~Revised by Herr Ing. W. Isendahl.~
