Excerpt from A Text-Book of Agricultural Zoology The subject treated in the following chapters, Agricultural Zoology, has perhaps been more neglected in England than any other branch of science applied to agriculture: even the name itself is hardly at present understood. It is true, indeed, that the labours of Curtis, and in later years of Miss Ormerod, have developed one branch of economic zoology - namely, the part played by insects in causing disease amongst animals and plants; it is true also that some of our veterinary surgeons have done excellent work on the other parasitic diseases of animals; but there remains a vast portion of the subject that has neither gained the attention of English scientific men nor been summarised in an English text-book. Agricultural Zoology treats of the life-histories, the habits, the peculiarities of all the animals which affect for good or for evil our stock and crops, whether on the farm or in the garden, and the structure and development of domestic animals. Parasitism plays an important part in this subject, especially in the worms; but the economic effects of parasites are not confined to worms the parasitic insects, the minute protozoa, equally take their annual and preventable toll of our flocks and herds.

Excerpt from College Zoology This book is intended to serve as a text for beginning students in universities and colleges, or for students who have already taken a course in general biology and wish to gain a more com prehensive View of the animal kingdom. It differs from many of the college textbooks of zoology now on the market in several important respects: (1) the animals and their organs are not only described, but their functions are pointed out; (2) the ani mals described are in most cases native species; and (3) the relations of the animals to man are emphasized. Besides serv ing as a textbook, it is believed that this book will be of interest to the general reader, since it gives a bird's-eye View of the entire animal kingdom as we know it at the present time. Within the past decade there has been a tendency for teachers of zoology to pay less attention to morphology and more to physiology. As a prominent morphologist recently said.

Excerpt from Outlines of Economic Zoology The book may be used in several ways. As followed by the author, the course may be given as a separate one to students who have already had the regular elementary course in general zoology. In this case the students will be familiar with the classification, structure and habits of most of the type forms discussed, but, if desired, additional labo ratory work may be arranged for the study of certain parasitic and other economically important forms not generally considered in a general laboratory course. Or, the text might be used in a beginning course in zoology by some amplification of the morphologic and other aspects and considerable increase in laboratory work. Again, it could well be used as supplementary reading with, say, one hour credit per semester for the year, in connection with the regular elementary course in general zoology. It is thought that, used in one or other of these ways or in some still different way, it should be especially useful to students in agriculture, who want a practical course. Various sources of information have been drawn upon, and recognized authorities in each subject consulted so far as possible. The publications of the Government, especially those of the Department of Agriculture, have been freely used and quoted. The figures have been borrowed largely, either from technical or from more popular works, whichever gave the best ideas of the animals portrayed; the source is indicated in every case. The brief bibliography at the end of the book is merely to aid the student, who may have become especially interested in some animal or group, to get more detailed information.
