   ANOTHER aeroplane with which experiments are being made at Morris Park is that of Mr. Wilbur M. Kimball, the Secretary of the Society, to which we referred in our issue of April 10th. It is of the biplane type, and is peculiar for the fact that it has eight propellers, 3 ft. 10 in. in diam., arranged between the planes, as seen in our photograph. The drive is by wire rope 1/8- inch in diameter, and the propellers are arranged in two sets of four, which are driven at a speed of 1,600 revs, per minute by a 4-cylinder motor 4-in. bore 4-in. stroke. From tip to tip the wings have a spread of 37 ft., and are 6J ft. wide, and placed 4 ft. 2 ins. apart. A special feature is the square tips 4 ft. by 4 ft., which are used for steering instead of flexing the wings. The planes of the elevator, which is fitted 9 ft. 9 ins. in advance of the main planes, measure 12 ft. by 12 1/2 ft., the distance between the two surfaces being 3 ft.
