Efficiency in weighing, checking and marking the only sav-ing is found in the use of automatic scales in placeof the ordinary beam scales. It has been found thatit requires an average of 10 sec. to weigh a truck loadof freight on automatic scales and 30 sec. to weighit on ordinary scales. The main advantage securedby this change is in the increased rapidity of handlingpossible. The saving- in labor will be the elimination. 4a* Fig. 1.

The superintendence item remains the same foralmost any system. Then with the labor cost of the system repre-sented in Fig. 1 as 100 per cent we may with amaximum investment, expect to reduce the labor costto about 24 per cent, using a very complete trans-portation and mechanical piling system. With asmaller investment this labor cost will increase untilwith manual loading, unloading and piling, and me-chanical transportation we find a labor charge run-ning up to about 55 per cent. To these labor charges must then be added:The operation cost of the mechanical system, includingoperators, power, maintenance and interest on the investmen
