THE PRINCIPLES OF POLITICS, an Introduction to the Study of the Evolution of Political Ideals, by A. R. Lord, M. A., professor of philosophy in the Rhodes University College, Grahamstown, South Africa. This book attempts to present a scientific criticism and exposition of political principles within the grasp of young students undertaking the study of political philosophy. Sir Frederick Pollock's brilliant lectures on the "History of Political Science" and Doctor Bosanquet's "Philosophical Theory of the States," the two leading authorities in this field are usually found too difficult and subtle for the students entering upon this field of study for the first time. This volume is intended as an introductory treatise to prepare the student for a fuller appreciation of the above mentioned authorities. The questions of the proper structure sphere and functions of the state, and the rights and duties

of the individuals are raised and admirably discussed in this brief but comprehensive treatise. Cloth, 306 pages, price $3.40. Clarendon Press, Oxford, England; American branch, 35 West 37th Street, New York.

THE COMMON-WORD SPELLERS, a TwoBook Course in Spelling for the Common Schools. Book One for grades 1-4 and Book Two for grades 5-8, by Ervin Eugene Lewis, Ph. D., superintendent of schools, Rockford, Illinois, formerly professor of education at the State University of Iowa. The Lewis CommonWord Spellers embody the most recent developments in this new pedagogy. In vocabulary, grading, and methods of presentation they mark an advance that the schoolman will be quick to appreciate. The vocabulary is based on original investigations conducted at the State University of Iowa by Dr. Lewis and Dr. W. N. Anderson. The words from 3,723 business and social letters, written by men in all sorts of professions, were carefully tabulated to ascertain those most widely used in ordinary correspondence. The results showed 3,000 words used five or more times. This list of 3,000 words has been made the basic list for the Common-Word Spellers. To it have been added 1,000 words chosen from the lists of Ayers, Cook and O'Shea, Pryor, Starch, Jones and others, including interest words from writing vocabularies of school children. The words in these spellers are carefully graded and the principles of phonics are used consistently to aid the child in learning to spell. Additional helps are supplied in the rules for spelling, pronunciation, and syllabication, and es pecially in the notes, which give concrete teaching suggestions. Book I for grades 1-4, 150 pages, price 56 cents; Book II for grades 5-8, 184 pages, price 60 cents. Ginn and Co., Boston, New York, Chicago.

ANIMAL HUSBANDRY, by John L. Tormey, B. S. A., assistant professor of animal husbandry, University of Wisconsin, Madison, and Rolla C. Lawry, B. S. A. This volume is one of the series of agricultural texts based on the theory that the successful farmer should know the physical and biological forces with which he has to contend; that he should understand the laws under which these forces operate; and that he should acquire some skill in directing them. Animal husbandry includes both the art of breeding, feeding and caring for live stock, and the fundamental laws of science upon which these practices are based. The ability of a stockman to raise and care for animals in a proper manner rests ultimately upon his knowledge of breeds, feeds and housing conditions. This volume has been prepared with the hope that its subject matter will, in some measure, meet the needs of

students of animal husbandry and create a deeper interest in the live stock industry. Cloth, 351 pages with index, price $1.40. price $1.40. American Book Co., New York, Cincinnati and Chicago.

This book is the outcome of successful classroom teaching wherein the children were made to feel their share in the welfare of the community. The use of this book should directly contribute to the making of better citizens
