About This Book

A practical, illustrated survey of the animal kingdom emphasizing species that affect crops, orchards, forestry, and farm environments. It outlines classification and anatomy of major groups—vertebrates, birds, mammals, insects, mites, nematodes, molluscs and other lower forms—then treats life cycles, habits, and the beneficial or harmful roles of common field and garden animals. Substantial coverage is given to insect pests and parasitic worms, with guidance on identification and control measures adapted for agriculture. Domestic livestock are largely excluded, and concise entries and figures aim to make technical material accessible to agricultural students and practitioners.

AUTHOR’S PREFACE.

The present volume of the Thaer Library was undertaken with the intention of providing agricultural colleges with a condensed review of the entire animal kingdom, but treating in greater detail the animals harmful or helpful to agriculture. I have, however, omitted all reference to the domesticated farm animals, as in all such institutions these are treated of, not by the zoologist, but by the lecturer on stock-breeding. Although the book is not allowed to exceed a certain size, I have taken great pains to make it intelligible, and venture to hope that it may be found suitable for the private use of the practical farmer. To the farmer who wishes more exhaustive information, and desires a reference book on the animal foes of agriculture, stock-breeding, horticulture, fruit-tree culture, and forestry, I venture to point out my larger work, Animal Foes and Friends,[1] brought out last year by the publisher of this book.
