classes in a large city high school, the students usually work 

 individually instead of in classes. The book contains 300 

 pages and nearly a hundred illustrations and is published by 

 P. Blakiston's Son & Co., Philadelphia. 



A new volume recently added to the Macmillan series 

 of Rural Manuals, under the editorship of L. H. Bailey, is 

 the "Manual of Fruit Diseases" by Lex R. Hesler and Her- 

 bert H. Whetzel. Beginning with two chapters on the 

 apple,- fourteen of our other principal fruit crops each have 

 a chapter devoted to the diseases that injure them. In 

 every case the cause of the disease is given, the symptoms 

 described and the methods of control, when any are known, 

 described in detail. A very comprehensive list of refer- 

 ences to the literature of the subject follows the account of 

 each disease. A chapter on the preparation and use of 

 fungicides closes the volume. The usefulness of the book 

 to the general reader is shown by the fact that it is singu- 

 larly free from the technical terms used by most writers on 

 plant diseases and that there is a glossary which defines the 

 few terms found necessary. The treatment of the subject 

 is most comprehensive. More than 450 pages are required 

 to cover the subject. There are also 125 good illustrations. 

 The price is $2. 



Doctor William Trelease, formerly Director of the 

 Missouri Botanical Garden and now professor of botany in 

 the University of Illinois, has issued a little book on "The 

 Plant Material of Decorative Gardening" into which he has 

 crowded a large amount of information about woody plants 

 for the use of landscape men. The book is small enough to 

 fit the pocket and yet contains references to more than 

 eleven hundred distinct species and varieties. All this 

 material may be identified by keys which make use of char- 

 acteristic features and therefore render long descriptions 

 unnecessary. The keys for the most part are based on bud, leaf.
