Excerpt from Insects Injurious to Forests and Forest Products: Damage to Telephone and Telegraph Poles by Wood-Boring Insects The writer on October 3, 1909, inspected some chestnut telegraph poles which had been standing for about twelve years on New York avenue, in Washington, D. C. The poles had been taken down under orders from the city authorities, which necessitated the placing of wires in conduits under ground, and they had been lying in piles for about a month before they were inspected. The chestnut telephone pole borer had been working in the base of the poles, and white ants, or termites, were associated with them. Twelve out of the 103 poles examined had been damaged, some more seriously than others. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
