THE AMERICAN BOTANIST

which they so deeply delight is merely an introduction to 

 dendrology and the things that really count with the public are 

 the economic and ecological aspects of the subject. The author 

 takes it for granted that her readers know the names of the 

 trees and proceeds at once to tell about the national forests, 

 cork and bark, midwinter forests, forest fires, the ascent of sap, 

 and kindred topics to the extent of nineteen chapters and more 

 than 200 pages. There are also about 60 illustrations. This 

 is one of the books that has gotten past the "How to Know" 

 stage and is all the better for it. It is published by A. C. 

 McClurg & Co., Chicago, at $1.50. 



Dr. William F. Ganong, Professor of Botany in Smith 

 College, has issued a ''Textbook of Botany for Colleges" from 

 the press of the Macmillan Company, New York. This is the 

 first of two volumes, or rather the first part of a larger volume, 

 intended to serve as an introduction to botany for those with- 

 out previous knowledge of the subject. The author's name is 

 sufficient guarantee that the information it contains is complete 

 and up-to-date, but the reader is likely to be impressed with the 

 fact that the presentation is dominated by the taxonomic 

 aspect of botany which is still sO' much in evidence in the 

 Eastern States. Many pages remind one vaguely of Gray's 

 ''How Plants Grow," though this is a greatly amplified account 

 of the subject with considerable economic and ecological matter 

 added. Since the book is designed largely for those who wish 

 a general acquaintance with botany, more attention is given 

 to the larger aspects of the subject than to minute details. The 

 sequence of the first part is leaves, stems, roots, flowers, fruits, 

 and seeds, with a discussion of the morphology and physiology 

 of each. The second part is to be devoted to the kinds and 

 relationships of plants. The first part contains 390 pages and 

 costs $2.00. 



It is not likely that Prof. W. R. G. Atkins' "Some Recent 

 Researches in Plant Physiology" will ever become popular with
