From that time the subject of mechanical invention took complete possession of him. With some rude tools which he contrived, he made a wooden clock that marked the hours with remarkable exactness; while he made for a miniature chapel the figures of some angels which waved their wings, and some priests that made several ecclesiastical movements. With the view of executing some other automata he had designed, he proceeded to study anatomy, music, and mechanics, which occupied him for several years. The sight of the Flute-player in the Gardens of the Tuileries inspired him with the resolution to invent a similar figure that should _play_; and after several years’ study and labour, though struggling with illness, he succeeded in accomplishing his object. He next produced a Flageolet-player, which was succeeded by a Duck—the most ingenious of his contrivances,—which swam, dabbled, drank, and quacked like a real duck. He next invented an asp, employed in the tragedy of ‘Cléopâtre,’ which hissed and darted at the bosom of the actress. Vaucanson, however, did not confine himself merely to the making of automata. By reason of his ingenuity, Cardinal de Fleury appointed him inspector of the silk manufactories of France; and he was no sooner in office, than with his usual irrepressible instinct to invent, he proceeded to introduce improvements in silk machinery. One of these was his mill for thrown silk, which so excited the anger of the Lyons operatives, who feared the loss of employment through its means, that they pelted him with stones and had nearly killed him. He nevertheless went on inventing, and next produced a machine for weaving flowered silks, with a contrivance for giving a dressing to the thread, so as to render that of each bobbin or skein of an equal thickness. When Vaucanson died in 1782, after a long illness, he bequeathed his collection of machines to the Queen, who seems to have set but small value on them, and they were shortly after dispersed. But his machine for weaving flowered silks was happily preserved in the Conservatoire des Arts et Métiers, and there Jacquard found it among the many curious and interesting articles in the collection. It proved of the utmost value to him, for it immediately set him on the track of the principal modification which he introduced in his improved loom.
