TIME WELL SPENT
Working as an ordinary hand in a Philadelphia shipyard was a man whose peculiarity was that, while others of his class indulged in merry-making, he was incessantly engaged in studying mechanical combinations. One of his companions secured a poodle-dog, and spent six months in teaching it how to execute a jig upon his hind legs. Knowlton spent the same period in discovering some method by which he could saw ship timber in a beveled form. The first man taught his dog to dance; Knowlton, in the same time, discovered a mechanical combination that enabled him to do in two hours the work that would occupy a dozen men, by slow and laborious process, an entire day. The result was that Knowlton rose to be a successful inventor, made a fortune, and showed the world the benefit of time well spent.
