Many years ago a very instructive fact on this point came under my own personal observation. A gentleman of my acquaintance had frequent need of the aid of a carpenter. The work to be done was not regular carpentry, but various odd jobs, alterations and adaptations to suit special wants, and no little time and materials were wasted in the perpetual misconceptions and mistakes of the successive workmen employed. At length a workman was sent who was a German, from the kingdom of Prussia. After listening attentively to the orders given, and doing what he could to understand what his employer wanted, Michael would whip out his pencil, and in two or three minutes, with a few rapid lines, would present a sketch of the article, so clear that any one could recognize it at a glance. It could be seen at once, also, whether the intention of his employer had been rightly conceived, and whether it was practicable. The consequence was, that so long as Michael was employed, there was no more waste of materials and time, to say nothing of the vexation of continued failures. Michael was not really more skilful as a carpenter than the many others who had preceded him. But his knowledge of drawing, gained in a common school in his native country, made his services worth from fifty cents to a dollar a day more than those of any other workman in the shop, and he actually received two dollars a day, when others in the same shop were receiving only a dollar and a quarter. He was always in demand, and he always received extra wages, and his work even at that rate was considered cheap. What was true of Michael in carpentry, would be true of any other department of mechanical industry. In cabinet-making, in shoe-making, in tailoring, in masonry, in upholstery, in the various contrivances of tin and sheet iron with which our houses are made comfortable, in gas-fitting and plumbing, in the thousand-and-one necessities of the farm, the garden, and the kitchen, a workman who is ready and expert with his pencil, who has learned to put his own ideas, or those of another, rapidly on paper, is worth fifty per cent. more than his fellows who have not this skill.
