Trees in winter 
In the past, tree manuals have either been without adequate illustrations 
or they have been too expensive for many who would otherwise have been 
students of tree life. The present volume? is inexpensive and yet each one of 
the more than roo species described is represented by excellent halftone 
reproductions of photographs of the winter habit, the fruit, the twigs, and the 
bark, making in all more than 500 separate illustrations. The book consists 
of two parts, the first devoted to the planting and care of trees and covering 
182 pages, and the second to descriptions of the tree species together with keys 
for their identification. The latter part, as it appeared in bulletin form, was 
reviewed in this journal? somewhat more than a year ago. 
The introductory chapter on the study of trees discusses the importance of 
the subject for various grades of school and college work, as well as the aspects 
which appeal to the amateur, the artist, and the poet. Some directions 
are given for conveniently measuring the height of trees without elaborate 
apparatus, and tree photography is briefly considered. There follows a series 
of chapters on the selection of trees for various purposes, their planting, and 
their care. This topic is expanded to include the treatment of various injuries 
and the control of insect and fungous enemies. 
The systematic part begins with a general chapter on the terms employed 
and their application to the description and identification of various species. 
It is followed by keys for (1) the genera and (2) the species. For the conifers, 
leaf and bud characters are employed; while for deciduous genera, the bud, 
leaf scar, and twig are made the principal bases of identification, with an 
occasional final appeal to the fruit. The description of species is concise, 
being limited to a single page for each, but quite sufficient for accurate deter- 
mination, and is supplemented with data concerning the distribution, character, 
and economic uses of the wood, together with synonyms for both common and 
scientific names. Facing the description is the plate illustrating the tree, 
making the arrangement very convenient. A good index adds to the efficiency 
of this excellent work. Its scope fits it for use in the college, the school, and 
the home.—Gero. D. FULLER.
