MACHINE OPERATORS n 5 f as e, the speed at which the apparatus worked made almost impossible even to see the cube’s position after lt: had been placed; for the arm would cover the cube be fore the hand could be taken away. Sometimes, the hand Was not taken away quickly enough and the revolving arm collided with it, slowing down its revolution. This w °uld still further increase the difficulty of scoring. Add to this the fact that it required the experimenter’s entire a ttention to keep the apparatus moving properly, and it be seen that the difficulties of obtaining a proper score 0n an individual’s performance were almost insurmount- abIe - This difficulty naturally deprived the apparatus of ^uch of its value as a test. A third important drawback the difficulty of revolving the arms at speeds which '''ere both constant and readily adaptable to the pur poses of the test. The electrical control which was tried w as found much too troublesome and expensive for the purpose. spite of these difficulties, it seemed as if the principle ^ the test were correct and, therefore, it was decided to esig n a s i m q ar apparatus which would obviate the dif ficulties found in the original. In designing this test, the step was to find out exactly what kind of work ma im st chine operators were doing. It seemed unreasonable from e outset to assume that one test could apply equally th Wel1 to all kinds of machine operators, for the work of °P e rators is as variegated as the work of clerks, stenog- ra phers, packers, assemblers, and others. If special tests ^ ere needed for these varieties of work, it seemed logical su ppose that machine operators of different kinds ^°uld also require different kinds of tests. Therefore, ai y one type of machine was chosen. The operation a hy chosen was that of hand-feed dial machines. A dial
