Jacquard’s achievement having come to the knowledge of the Prefect of the Department, he was summoned before that functionary, and, on his explanation of the working of the machine, a report on the subject was forwarded to the Emperor. The inventor was forthwith summoned to Paris with his machine, and brought into the presence of the Emperor, who received him with the consideration due to his genius. The interview lasted two hours, during which Jacquard, placed at his ease by the Emperor’s affability, explained to him the improvements which he proposed to make in the looms for weaving figured goods. The result was, that he was provided with apartments in the Conservatoire des Arts et Métiers, where he had the use of the workshop during his stay, and was provided with a suitable allowance for his maintenance. Installed in the Conservatoire, Jacquard proceeded to complete the details of his improved loom. He had the advantage of minutely inspecting the various exquisite pieces of mechanism contained in that great treasury of human ingenuity. Among the machines which more particularly attracted his attention, and eventually set him upon the track of his discovery, was a loom for weaving flowered silk, made by Vaucanson the celebrated automaton-maker. Vaucanson was a man of the highest order of constructive genius. The inventive faculty was so strong in him that it may almost be said to have amounted to a passion, and could not be restrained. The saying that the poet is born, not made, applies with equal force to the inventor, who, though indebted, like the other, to culture and improved opportunities, nevertheless contrives and constructs new combinations of machinery mainly to gratify his own instinct. This was peculiarly the case with Vaucanson; for his most elaborate works were not so much distinguished for their utility as for the curious ingenuity which they displayed. While a mere boy attending Sunday conversations with his mother, he amused himself by watching, through the chinks of a partition wall, part of the movements of a clock in the adjoining apartment. He endeavoured to understand them, and by brooding over the subject, after several months he discovered the principle of the escapement.
