England. By K. J. J. Mackenzie, M.A., with a preface and chapter by 

 F. H. A. Marshall, Sc.D. Demy 8vo. ■ 75. dd. net. 



In this book the author makes a strong plea for agricultural reform ; he drives home 

 the lessoa, taught us by the war, of the folly of relying upon other countries for food 

 that might be produced at home, and specially urges the need of co-operation 

 amongst fanners, of the development of "dual-purpose" cattle, and, above all, of 

 systematic research on the part of scientists into the many problems of modern agri- 

 culture. Dr Marshall contributes a chapter on the physiology of cattle.
