Excerpt from Farm Friends and Farm Foes: A Text-Book of Agricultural Science This book is intended to serve as a text and guide for the study of those plants and animals so vitally related to crop production as often to determine success or failure therein. The information given embodies the latest re searches of that host of investigators who have done such great service in the advancement of agriculture in recent years. The text has been so combined with directions for observation and expression that it is hoped that teachers will be able to lead their pupils to a first-hand knowledge of the most important plants, insects, birds, and mammals to be found in the region of the school. Most of the original engravings are from drawings by Mr. W. I. Beecroft, a few being adapted from the publica tions of authors to whom credit is given in the list of illus trations.' Many of the insect pictures are from woodcuts originally made for the classic report on [meets [njun'ous to Vegetation, by Dr. T. W. Harris, for the use of which thanks are returned to Mr. J. Lewis Ellsworth, Secretary of the Massachusetts State Board of Agriculture. For courtesies in connection with other illustrations I am in debted to Misses Hazel Dearth, Alice Manning, and I. S. Cragin, and Messrs. James Hall, A. G. Randall, E. D. San derson, A. D. Selby, A. H. Verrill, and C. W. Woodworth, as well as to the Experiment Stations of Illinois and New Hampshire and the United States Department of Agri culture. I have also to thank Mr. W. F. Fiske, of the Gypsy Moth Laboratory, for kindly reading the proof of the chapters on Predaceous and Parasitic Insects.
