EMPLOYMENT PSYCHOLOGY 118 ally dropped off; but eighteen minutes was more than enough time for testing one subject. In addition to this, the difficulty of the test could be varied not only by in creasing the revolutions per minute but by decreasing the size of the slot. By means of the slides, these slots could be so shortened as to obtain practically the same effect as that obtained by increasing the speed of the machine, though with far less effort. The preliminary study of typical dial machines had revealed that the fundamental requirement was the ability to acquire a certain bodily rhythm in feeding material into the dial and in timing the movements of the hand and arm with those of the machine. Some operators acquired this rhythm very readily, others only after a long time, and still others never. The problem, therefore, was to detect these differences so that the most likely candidates could be placed at the most difficult machines, the less likely at the slower machines, and those who failed entirely at work of another kind. When the apparatus described was put into use, it soon became evident that it re quired a knack similar to that required by dial-machine operators, and also that it divided the people who tried it into radically different classes. The point which re mained to be proved, however, was that those who were slow in this test were also slow as dial-machine operators and vice versa. In order to determine this, ninety-six dial-machine operators in three different shops were tested. One of these shops contained slow dial machines, the other two contained fast machines. Each operator was given three trials of two minutes each, the first two being given with the slot wide open, the third with the slot half closed. The revolutions per minute were kept constant through out. The results were then compared with the piece-work
