The man who first started on these lines was a German, namedLilienthal. His methods have been much imitated in Franceand America, and require to be fully described in order to under-stand the problem of floating motion. When he was a schoolboy,he tried the most primitive methods. He fastened wings to hisbody, and tried to get sufficient impetus for the start by running.

Later on, with the help of his brother, he usedsails, which were distended to represent the wings of a bird, andmade of calico, supported on a frame of wickenvork. He satwith the lower part of his arms resting on the frame ; in thisway he controlled the movements of his machine. In a strongwind, he would soar above the heads of the astonished spectators ;under other conditions, he would appear to float, almost at simple type of sail led Lilienthal to develop other designs,wdth a view to having greater control over the force of the wind.
