I waited anxiously. Twenty long minutes passed. At last he entered the room, and from a lively expression in his countenance I observed in a moment that the great object of my long-cherished ambition had been attained. He expressed, in good round terms, his satisfaction at my practical ability as a workman, engineer, and mechanical draughtsman. Then, opening the door which led from his library into his beautiful private workshop, he said, "This is where I wish you to work, beside me, as my assistant workman. From what I have seen there is no need of an apprenticeship in your case." One of his favorite maxims was, "First _get a clear notion_ of what you desire to accomplish, and then in all probability you will succeed in doing it." Another was, "Keep a sharp lookout upon your materials; get rid of every pound of material you can _do without_; put to yourself the question, 'What business has it to be there?' avoid complexities, and make everything as simple as possible." Mr. Maudsley was full of quaint maxims and remarks,--the result of much shrewdness, keen observation, and great experience. They were well worthy of being stored up in the mind, like a set of proverbs, full of the life and experience of men. His thoughts became compressed into pithy expressions exhibiting his force of character and intellect. His quaint remarks on my first visit to his workshop and on subsequent occasions proved to me invaluable guides to "right thinking" in regard to all matters connected with mechanical structure. On the morning of Monday, May 30, 1829, I began my regular attendance at Mr. Maudsley's workshop, and remained with him until he died, Feb. 14, 1831. It was a very sad thing for me to lose my dear old master, who always treated me like a friend and companion. At his death I passed over into the service of his worthy partner, Joshua Field, until my twenty-third year, when I intended to begin business for myself. I first settled myself at Manchester, but afterwards established a large business outside of Manchester on the Bridgewater Canal. In August, 1836, the Bridgewater Foundry was in complete and efficient action. The engine ordered at Londonderry was at once put in hand, and the concern was fairly started in its long career of prosperity. The wooden workshops had been erected upon the grass, but the greensward soon disappeared. The hum of the driving-belts, the whirl of the machinery, the sound of the hammer upon the anvil, gave the place an air of busy activity. As work increased, workmen multiplied. The workshops were enlarged. Wood gave place to brick. Cottages for the accommodation of the work-people sprung up in the neighborhood, and what had once been a quiet grassy field became the centre of a busy population.
