On a recent piece of work, the steam drills, of which there were 14, were averaging 4 feet of hole drilled per drill hour, the drillers were getting 30 cents per drill hour, and helpers 18¾ cents. For a period of ten days the drills were kept under the personal supervision and instruction of the expert in charge; and at the end of that time a bonus of 2 cents per foot for everything above 70 feet in 8 hours was offered to the men. On this basis no one could get a bonus unless he did 100 per cent better than the average previously attained. Exceedingly cold weather intervened, preventing a good deal of drilling; but within two weeks of the return to normal weather conditions, the average drill output rose to over 6 feet per drill hour, and one man obtained the remarkable record of 142 feet in 9 hours, or over 15.7 feet per drill hour. On this work a careful record was kept day by day, of the performance of each man; and the men who had a consistently low average were gradually discharged, thereby helping out the bonus system. The men were also under more or less constant instruction, and therefore the improvement was not entirely due to the bonus system. A further modification of the bonus system is advisable in some cases, where an extra bonus is given for exceedingly high performance, such, for example, as paying the men an extra cent bonus, making 3 cents above, say, 90 or 100 feet per 8 hours. It is well, however, to apply this modified arrangement only after there has been an elimination of the poorest men. When possible, the payment of bonuses should be made at very short intervals, and not left to a monthly settlement. [Illustration: A CORNER IN THE LAUNCH BUILDING SHOP OF THE GAS ENGINE & POWER CO.

The methods above indicated will keep the men on the _qui vive_ during the day. A very valuable improvement can be instituted if the more intelligent among them can be led to think about their work after working hours. This must necessarily be done in rather a subtle way. Posting records at the end of the day's work so that the men see them on their way home, will do a great deal toward keeping the subject alive until the next morning. When the men have been led to a state where they discuss with each other the methods of improved efficiency, for the following day amazing results can be counted upon.
