He began to build gliders, but had no success with them until he found out for himself what he had not gathered from his reading of Lilienthal--that an up-current of wind is necessary for a prolonged glide. His first successful flight was made with his fourth glider on the 7th of December 1901. He got into touch with Mr. Chanute, another of Lilienthal's scattered disciples, and through him was supplied with papers and photographs concerning the gliding experiments of the Wrights. These were a revelation to him, and he used them in making his fifth glider, which was a great improvement on its predecessors. He lectured at Lyons to the Aero Club of the Rhone on the progress of aviation by means of gliding, and published his lecture in the _Revue d'Artillerie_ of March 1904. About this time the air was full of rumours of flight. M. Ernest Archdeacon, of Paris, took up the subject with ardour, wrote many articles on it, and encouraged others to work at it. A young man, called Gabriel Voisin, who heard Captain Ferber lecture at Lyons, came on to the platform after the lecture and declared that he wished to devote his life to the cause of aviation. The next morning he started for Paris, and with the help of M. Archdeacon founded the earliest aeroplane factory in France--the firm of the brothers Voisin, which became the mainstay of early French aviation. Ferber himself was carrying out a series of experiments at Nice with an aeroplane which he fitted with a six horse-power engine and suspended from a tall mast, when he was invited by Colonel Renard to help with the work of the official research laboratory at Chalais Meudon. He joined the staff, but found that the officials of a Government organization are as ill qualified as the theorists of a university for progress in practical invention. The lower members of the hierarchy are men under orders, who do what they are told to do; the higher members are hampered by having to work through subordinates, who often do not understand their aims and take no particular interest in the work in hand. Nevertheless, he improved his aeroplane, stabilizing it by means of a long tail, and fitting it with wheels for landing, in place of the skids which were used by the Wrights. Then, like those who had gone before him, he was held up by the question of the engine. Engineers are a conservative race of men, and perhaps the perfected aeroplane would still be waiting for a suitable engine if they had not been prompted to innovation by the fashion of motor-racing. There are strange links in the chain of cause and effect; the pneumatic tyre made the motor-bicycle possible; for motor-bicycle races a light engine was devised which later on was adapted to the needs of the aeroplane. Ferber made acquaintance with M. Levavasseur, who had invented an engine of eighty horse-power weighing less than five pounds per horse-power, and had won many races with it. This engine was named the _Antoinette_ in honour of the daughter of M.
