. Bulletin of the Department of Agriculture. Agriculture; Agriculture. S^^'^'mTU Contribution from the Forest Service HENRY S. GRAVES, Forester. Washington, D. C. PROFESSIONAL PAPER January 24, 1917 POLES PURCHASED, 1915. By Arthur M. McCreight. INTRODUCTION. The Forest Service, through its Ofhce of Industrial Investigations, has compiled statistics on the number of poles purchased during 1915 in the United States by the telephone and telegraph companies,, steam and electric raih-oads, and electric light, heat, and power companies. The census was taken exclusively by correspondence^ with approximately 17,000 purchasers, representing practically all the pole users in the country. About 12,000 concerns returned schedules in reply to either the first or the second request for data. This was 70 per cent of the total number of concerns to which inquiries were sent. Actually, however, the figures given in this bulletin rep- resent between 90 and 95 per cent of the poles purchased, because the nonreporting companies were principally the smaller ones. Information regarding the prices paid for the various species of poles was not requested. Table I shows the number of poles purchased each year from 1907i to 1911 and for the year 1915, by kind of wood. Figures for 1911 and previous years were taken from reports compiled in cooperation with the Bureau of the Census. Statistics were not obtained for the years 1912 to 1914.
