Abstract
A MERICA is confronted squarely with the problem of increasing her productivity per man power without, at least, increasing the cost of production per article. This in addition to any economies that may be effected through national obedience to the slogan Produce more, save more and waste less. Such increased productivity per man power must come about through more efficient utilization of fuel, water power and machinery.
