Excerpt from Some Insects Injurious to Forests: The Western Pine-Destroying BarkbeetleThe object of this paper is to give available information on. This insect and methods of combating it, with special reference to the results of investigations by the writer during the summer of 1905 in central Idaho.The need of the investigations was suggested in a letter dated August 10, 1904, from Mr. Gifford Pinchot, forester of the U. S. Department of Agriculture, to Dr. L. 0. Howard, chief of the Bureau of Entomology, as follows: I learn from the Payette Lumber and Manufacturing Company, one of the Weyerhaeusers, whose land lies on the Payette River north of Boise, that the pine in their holdings is said to be dying from the attacks of insects. If it were possible for you to assign Doctor Hopkins, or one of his assistants, to make examination of this region, unless it has already been done, I should greatly appreciate it, and I should likewise appreciate your sending to Mr. Edgar M.Hoover, general manager of that company at Boise, any information you may have bearing on this subject.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
