Durham Christmas Aeroplane Sales & Exhibition Corporation, Inc. 1913. Capital: $10,000 to $50,000. Claims for it are that it is "automatically balanced." This is attained by the shape of the machine, not through the agency of any auxiliary apparatus. [Illustration] CORDEAUX-ETTER. Cordeaux-Etter Mfg. Corporation, Brooklyn, N.Y. Capital: $10,000.

Curtiss Aeroplane Co., Hammondsport, N.Y. Glenn H. Curtiss in 1907 and 1908 was a member of the Aerial Experiment Association, formed by Dr. and Mrs. Alexander Graham Bell. This Association built four machines, each along the lines of one of the four engineers belong to the Association, F. W. Baldwin, Lieut. T. E. Selfridge, G. H. Curtiss and J. A. D. McCurdy. The last built was the _June Bug_, designed by Curtiss and was the most successful. In the spring of 1908, the Association was disbanded and The Aeronautical Society gave Curtiss an order for an aeroplane with _carte blanche_ as to design. He produced a 4 cyl. machine, Curtiss engine, and flew it. A duplicate was hurriedly built, 8 cyl. engine installed, and taken to Europe for the first Gordon Bennett, which he won. Returning, the same type was continued with minor improvements. Later the front elevator was brought closer in, finally discarded, and the fan tail adopted and this remains the standard land machine to-day. In April, a military tractor was built and flown.
