On the 15th of February, 1819, without the loss of a day, he began work with a piano-maker. He had now entered upon what he meant should be the business of his life, and he was resolved that he would be master of it. From the first he took rank in his employer's factory as the most careful workman in it. He spared no pains to make his knowledge full in every detail. Time was of no consequence compared with knowledge, and he was never anxious to hurry through with his work. It soon came to be recognized by his employer and fellow-workmen that he was the best fitted for those portions of the work upon the instrument which required the greatest patience as well as the greatest care, and the most difficult and delicate work was always intrusted to him, his wages being, of course, in proportion. Other men had no thought but to earn a living. This man meant to win fame and fortune, and to enlarge the scope of that art to which he was so passionately devoted. He labored with his mind as well as his hands, familiarizing himself with every detail of the manufacture, and devising in silence the means for improving the instrument and the implements used in its construction. He could afford to wait, to be slower than his fellows. Every moment spent over his task made his workmanship the better, and opened to his mind new sources of improvement. He spent three years as a journeyman, and then went into business for himself. He associated himself with a Mr. Stewart, under the firm of Stewart & Chickering.
