Excerpt from Some Insects Injurious to Forests: The Western Pine-Destroying Barkbeetle The 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 Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

The insects presented in this book are among the most common and the most destructive found on what are considered to be the most important tree species; namely, spruce, larch, pine, oak, maple and poplar.It is intended for use by both scientists and by practising foresters. To make the information contained in this volume more easily accessible, insects are grouped according to the tree species that they attack rather than by their entomological classification, and, for this reason, insects found on a given tree species are presented in the same chapter. The annual reports of the Forest Insect and Disease Survey have provided most of the information on history of outbreaks that is found in the text.
