REVIEWS AND NOTICES OF BOOKS. 239 



In each case abundant detail is set forth. The student of 

 forest entomology, and especially the working forester, will find 

 in the book a mass of material largely drawn from the eminent 

 authors cited, whose works are not always easily accessible, 

 while he cannot fail to be impressed with the enthusiasm of 

 the author for his subject, and with the assiduity and industry 

 he has displayed in the production of his book. To break 

 ground in Britain with a new text-book on Forest Entomology 

 was no easy task. Mr Gillanders deserves, and will receive, 

 the warmest acknowledgment of his efforts. The book is 

 illustrated with numerous figures, some of them very good. 

 To say that Messrs Blackwood are the publishers is to say that 

 nothing is wanting in the get-up. 



Trees and Their Life- Histories. By Percy Groom. London : 

 Cassell & Co. Price 25s. net. With 512 Illustrations. 



This book forms a most welcome addition to the literature of 

 Forest Botany. The author has been very successful in his 

 endeavour to place before the reader a simple and clear account 

 of the life and growth of the various forest-trees with which he 

 deals. The volume is lavishly illustrated by typical and well- 

 chosen photographs showing the trees as they appear at 

 different seasons of the year, and also the characteristic features 

 of their various parts, such as bud, flower, fruit, leaf, twig, root, 

 and bark. 



The trees dealt with are treated under the two classes 

 Gymnospermae and Dicotyledones. In his Introduction Professor 

 Groom has given a very interesting organographical description 

 of the different parts which compose the tree. He has evidently 

 taken pains to write this Introduction in such a way that the 

 non-botanical reader might have no difficulty in understanding 

 clearly, and appreciating the importance to the tree of its various 

 organs, and thus to profit by what follows. In the other two 

 parts of the volume the individual life-histories of the two great 

 classes of trees are given. In describing the special life-history 

 of each tree, no point of importance has been omitted, and the 

 written account, together with the photographs given to illustrate 

 the various points, present to the student a complete picture of 

 the different phases through which the tree passes in its growth
