MILITAKY AERONAUTICS— SQUIEK. 135 



The motor is an eight-cylinder Antoinette of 50 horsepower 

 weighing ITG pounds, and developing about 38 horsepower at 1,050 

 revolutions per minute. 



The propeller is a built-up steel frame covered with aluminum 

 sheeting, Ti feet in diameter, wnth a pitch of 4 feet 7 inches. It is 

 mounted directly on the motor shaft immediately in rear of the mid- 

 dle of the main surfaces. 



The framework is of wood, covered with canvas. A chassis of steel 

 "tubing carries two pneumatic-tired bicycle wheels. Two smaller 

 wheels are placed under the tail. The total weight of the machine 

 is 1,166 pounds. The main surfaces support a little over 2 pounds 

 per square foot. The machine has shown a speed of about 28 miles 

 per hour and no starting apparatus is used. 



On January 13, 1908, Farman won the Grand Prix of the Aero 

 Club of France in a flight of one minute and twenty-eight seconds, 

 in which he covered more than a kilometer. It is reported that on 

 October 30, 1908, a flight of 20 miles, from Mourmelon to Rheims, 

 was made with this machine. 



The Bleriot Aeroplane. 



Following Farman's first flight from town to town, M. Bleriot 

 with his monoplane aeroplane made a flight from Toury to the neigh- 

 borhood of Artenay and back, a total distance of about 28 kilometers. 

 He landed twice during these flights and covered 14 kilometers of 

 his journe}^ in about ten minutes, or attained a speed of 52 miles an 

 hour. 



The June Bug. 



The June Bug was designed by the Aerial Experiment Association, 

 of which Alexander Graham Bell is president. It has two main 

 superposed aerosurfaces with a spread of 42 feet and 6 inches, includ- 

 ing Aving tips, with a total supporting surface of 370 square feet. 



The tail is of the box type. The vertical rudder above the rear 

 edge of the tail is 30 inches square. The horizontal rudder in front 

 of the main surfaces is 30 inches wide by 8 feet long. There are four 

 triangular wing tips pivoted along their front edges for maintaining 

 transverse equilibrium. The A'ertical rudder is operated b}^ a steering 

 wheel, and the movable tips by cords attached to the body of the 

 aviator. 



The motor is a 25-horsepower, 8-cylinder, air-cooled Curtiss. The 

 single wooden propeller immediately behind the main surfaces is 6 

 feet 2 inches in diameter and mounted directly on the motor shaft. 

 It has a pitch angle of about 17° and is designed to run at about 1,200 

 revolutions per minute.
