Thomas A. Edison, with his characteristic habit of epitomizing in a few terse words the most complex of problems, has recently said: Every business man should speed up his sales or ganization. The salesmen of the country can do more than anyone else to keep the wheels of industry turning at full speed. The salesman had to take a back seat during the war, but his time has now come. Give him a chance. Mr. Edison has not overstated the impor tance of salesmanship in the post bellum period, of ten years or more, that is destined to mark an entirely new epoch in the indus trial history of this country.
