"Mushrooms and their Cultivation." By T. W. Sanders. 8vo., 

 80 pp. (ColKngridge, London, 1909.) Is. net. 



This book on mushrooms and other edible fungi is specially written 

 for amateurs, but even professional growers may gain much valuable 

 information from its pages. It is a thoroughly practical work, and 

 crammed from cover to cover with useful instruction of how a man 

 with even the smallest garden may grow these delicious fungi. There is 

 a good index. 



" Agricultural Botany, Theoretical and Practical." By J. Percival, 

 M.A., F.L.S. Ed. 4. 8vo., xiv. + 828 pp. (Duckworth, London, 

 1910.) 7s. 6d. net. 



The fourth edition of this excellent text-book has been revised and 

 some additions made, including a chapter on the Linaceae. By the 

 excellence of its matter and the clearness of its arrangement this book 

 long since commended itself alike to teacher and taught, and it well 

 maintains its high position so that it may be regarded as indispensable 

 to the horticultural and agricultural student. 



" The Boy's Own Nature Book. " By W. Percival Westeh, F.L.S. 

 With a chapter and numerous illustrations by the Eev. S. N. Sedg- 

 wick, M.A. 8vo., xvi. +374 pp. (Eeligious Tract Society, London, 

 1908.) 3s. 6d. 



This volume of rather discursive stories of animal and plant life 

 will interest many a boy and girl in country sights and sounds. It is 

 well illustrated from photographs, and though some are rather more 

 curious than important, all add to the interest of the book. In addition 

 to the illustrations in the text there are two folding plates in a pocket 

 at the end of the book showing the caterpillars and chrysalides of 

 British Butterflies and Moths and British Butterflies in colours, while 

 two Appendices give annotated lists of these. Any boy with an em- 

 bryonic love of nature would welcome this as a gift or prize we are sure.
