Insect Pests and Fungus Diseases of Fruit and Hops. 



A Complete Manual for Growers. By P. J. Fryer, F.I.C, F.C.S. 

 Crown 8vo. With 24 plates in natural colours and 305 original photo- 

 graphs and diagrams. 45s net. 



The present volume represents a careful and painstaking attempt to produce as 

 complete a book of reference as possible, suited to the requirements of the fruit and 

 hop grower, and presented in such a form that the information, while given with 

 scientific precision, is also in a readily available form. 



"In modern commercial fruit culture results depend very largely on the grower's 

 ability to control the insect pests and fungous diseases which attack his trees. To 

 assist him in this work he has long needed a reliable handbook covering the whole 

 subject, enabling him to identify his enemies without loss of time, and indicating the 

 best and up-to-date methods of control. Such a book it has been the object of the 

 author of this volume to supply, and it may be said at once that he has succeeded 

 admirably. . . . He has a particularly clear and orderly style of presenting his facts, 

 giving all the information necessary to the practical man without forcing him to sift out 

 unessential details. . . . Altogether the book deserves to become the standard reference 

 work for growers." — The Gardeners' Chronicle 



Cattle and the Future of Beef- Production in 



England. By K. J. J. Mackenzie, M.A. With a Preface and 

 Chapter by F. H. A. Marshall, Sc.D. Demy 8vo. 7s 6d net. 



"One of the best treatises issued in recent years on the breeding and feeding of 

 cattle. . . . Mr Mackenzie's main plea is for better bred, better handled, and more 

 economically finished animals. . . . The chapters on dual purpose cattle, pedigree 

 breeding, dairy shorthorns, and future possibilities are generally excellent. . . . 

 Dr Marshall's chapter on physiology contains a great deal of valuable matter in small 

 compass." — The Agricultural Correspondent of The Glasgow Herald

 assistance. . . . The war period has given us no more opportune or valuable book 

 for farmers." — The Times 



British Grasses and their Employment in Agriculture.
