Excerpt from Preservative Treatment of Wood Poles, Vol. 2 The annual requirements for construction and replacement as shown by statistics compiled by the United States Forest Service for the year 1915 and for several years prior to 1911 are in excess Of poles. Of the poles purchased in 1915 about 61 per cent were cedar, principally northern and western, 16 per cent were chest nut and 13 per cent pine. The remainder were other timbers. Of the total number purchased, 41 per cent were used by telephone and telegraph companies, 3 5 per cent by electric light, power and street railway companies and 24 per cent by steam railways. The 1915 re port showed a notable increase in the number of pine poles purchased. These were principally short length poles and were used by the elec tric light, power and street railway companies. This enormous demand for poles has produced a constantly de creasing supply and constantly increasing costs Of production as log ging is carried on in more and more inaccessible districts. The large increase in cost to the user in the last decade has turned attention to the use of pole timbers formerly considered less desirable and to the use of preservatives to increase the life Of poles Of all classes. The importance Of these matters has led to a survey Of the conditions in Indiana and to the preparation Of this circular on the subject of the Preservative Treatment of Wood Poles.
