"But it is suddenly discovered by an industrial diagnosis that the machine has never been properly operated, even by the most skilled operators. It has been proved that 'there is more science in the most "unskilled" task than the man who performs it is capable of understanding.' This dictum of Mr. Taylor, a practical experimenter, has been dramatically proved in many directions. In the task of the sand shoveler, or the iron lifter, for instance, it was proved that by scientifically undertaking such work, fifty selected men, properly drilled, scientifically rested, intelligently manoeuvred, could accomplish a third more than one hundred ill selected and improperly managed men, in less time and under a larger salary. It is suddenly found that, contrary to theory, a machine, to be economically operated, leaves open man's chance for skill and does not rob him of it." Perhaps a few cases taken from our records will indicate how men of this kind are able to come up from slavery and take successful places in their true vocations. FROM BOILER-ROOM TO CHIEF ENGINEER'S OFFICE G---- manifested very early indications of the lure of machinery for him. While yet in his cradle, he would play contentedly for hours with a little pulley or other mechanical trifle. Before he was able to walk, he could drive nails with a hammer sturdily and with more precision than many adults. This also was one of his favorite amusements, and it was necessary to keep him provided with lumber, lest he fill the furniture with nails. As he grew older he became more and more interested in machinery and mechanical things. He took to pieces the family clock and put it together again. He nearly always had the sewing machine partly dismantled, but could always put it together again, and it usually ran better after he had finished his work. He built water-wheels, wind-mills, and other mechanical toys. When he was about fourteen years old he built a steam engine. He used a bicycle pump for the cylinder and pieces of an old sewing machine, a discarded wringer, some brass wires, and other odds and ends for the rest of the parts. So perfect mechanically was this product that when steam was turned on it ran smoothly, and with very little noise, at the rate of three thousand revolutions a minute. In this engine he employed a form of valve motion which he had never seen, and which had never been used before. While not particularly efficient, and therefore not a valuable invention, it at least showed his ability to adapt means to ends mechanically.
