THE NIEUPORT MONOPLANE. Photo, M. Branger. This exceedingly interesting machine, which won the great French Military Trials, is generally admitted to be one of the most efficient flying machines in existence. A similar machine can be seen at work in Hendon, where it is piloted by Mr. Grahame-White. ............................... BRITISH-BUILT SCOUTING MONOPLANE. This aircraft, an exceedingly fast, single-seated machine, represents the type of machine now favoured by French authorities for urgent, rapid, general reconnaissance. Its constructors are Messrs. Short Brothers. ...... READY FOR A SCOUTING FLIGHT. Here a latest-type reconnoitring monoplane, with its observer in the front seat and the pilot behind him, is seen just about to start upon an aerial voyage. The machine is a British-built Bristol, such as will be used in the forthcoming military trials. .................................................. TWO-SEATED, BRITISH-BUILT WAR MACHINE. The Blackburn military-type monoplane, with accomodation for pilot and observer, has already made many successful flights; and it is expected to perform meritoriously in the War Office trials. In some respects it resembles the graceful Antoinette. ................................ THE ENGINE-IN-FRONT BIPLANE. With the above machine—a type increasingly used for Service work—the Naval officers now experimenting at Eastchurch, Isle of Sheppy, have been carrying out recent tests. It was designed, and built, by Messrs. Short Brothers, who are now constructing special aeroplanes for Naval use. ........ MILITARY BIPLANE WITH TWO ENGINES. This exceedingly interesting machine, which possesses especial significance from the military point of view, is equipped with two Gnome motors.
