That is, all three sets of motions were used to do identically the same type of work, the only difference being that Set One was used to teach the beginner, Set Two was used when working slowly, and Set Three was used when working rapidly. I looked at my sec- ond teacher. He also had three sets of motions. From that day I continued to observe as far and as fast as I could, and have found in practically every case that every worker has at least three distinct sets of motions for doing the same work. “ Naturally, as time went on, I came to ask my various teachers,‘What is the quickest way ? ’ Each one had his own special ‘ kinks,’ or short cuts, such as putting two bricks together in the air and then placing them together in the middle of the wall. Of course, I had to try out each of them, but soon found the great difficulty of
