By CHAS A. PUBLOW. This book is entirely different from the usual type of dairy books, and is undoubtedly in a class by itself. The entire subject of butter-making in all its branches has been most thoroughly treated, and many new and important features have been added. The tests for moisture, salt and acid have received special attention, as have also the questions on cream separation, pasteurization, commercial starters, cream ripening, cream overrun, marketing of butter, and creamery management. Illustrated. 5 x 7 inches. 100 pages. Cloth. Net, $0.50 Questions and Answers on Milk and Milk Testing By CHAS. A. PUBLOW, and HUGH C. TROY. A book that no student in the dairy industry can afford to be without. No other treatise of its kind is available, and no book of its size gives so much practical and useful information in the study of milk and milk products. Illustrated. 5 x 7 inches. 100 pages. Cloth. Net, $0.50 Soils By CHARLES WILLIAM BURKETT, Director Kansas Agricultural Experiment Station. The most complete and popular work of the kind ever published. As a rule, a book of this sort is dry and uninteresting, but in this case it reads like a novel. The author has put into it his individuality. The story of the properties of the soils, their improvement and management, as well as a discussion of the problems of crop growing and crop feeding, make this book equally valuable to the farmer, student and teacher. Illustrated. 303 pages. 5½ x 8 inches. Cloth. Net, $1.25 Weeds of the Farm Garden By L. H. PAMMEL.
