Withthe development of aerial aviation seapower will become a secondary question, and it is gratifying to note that Great Brit-ain is taking up the subject. home in Nova Scotia. The late Lieut.Selfridge went up in this man-lifting kite, and it was hoped to get data as to the liftand what is technically called drift or re-sistance, with a view to installing a motorand propellers to convert the kite into afree-flying machine. The flight was en-tirely satisfactory, but unfortunately thekite was wrecked by being pulled throughthe water after it had come down. The association then moved its head-quarters to the engine works of Mr. H.G. Curtiss, who was executive head ofthe association. Gliding experimentswere commenced. For these gliding ex-periments the association adopted theChanute type, and obtained some usefulinformation from it before building their. Half-Way Over the Final Course, J. A, D, McCurdy, Aviator. Speaking of the possibilities of the aero-drome, Dr. Bell said: It is a practicalcertainty the machines will be used forsport in the very near future. At presentwe get a speed of forty miles an hour, andthere is no reason why we should not dou-ble that. In October, 1907, Dr. Alexander GrahamBell organized an association to be knownas the Aerial Experiment Association.The association consisted of five membersand had as its object the building and im-provement of heavier-than-air machines. Experiments were first made with alarge tetrahedral kite at Dr. Bells summer first motor-driven machine. SelfridgesRed Wing, as this machine was called(because the surfaces were winglike andcovered with red silk), was a distinct de-parture from the flat Chanute type. The main supporting surfaces werebowed toward each other at the extremi-ties, and tapered from fore to aft like abirds wing. The machine was fitted with runnersand
