The author of this book attaclied to the Auchland Training College, New Zealand, where the science of dairying an important subject of study. The book is a text-book, and is intended for use in secondary and technical schools. The treatment is therefore elementary. The science of dairying embraces many different branches of study. There is first the chemical and bacteri- ological side. In regard to these the book concise information as to milk analysis and control of bacteria. ^Methods of cream separation are also dealt with fully, followed logically by an account of methods of butter and making. .Just as in agriculture we have to study the plant as well as its products, so in dairying the cow must be studied. This resolves itself into physiology, and feeding and the study of diseases. Selection and breeding, and herd-testing are also important matters. The book under review is, as already intimated, a school book—simple, practical, and comprehensive. Questions are given at the end of each chapter. There is a special chapter on dairy arithmetic. The illustrations throughout are lent. Planters in tlie West Imlies wlui give .special attention to milk production and butter making, even though it be more in the nature of a hobby than a business, would find this book very useful and interesting.
