Trees in Winter.— Every observer knows that there are other 
ways of recognizing animals and plants than those given by the 
books, and we all welcome every addition to the literature of these 
occult ways of coming into touch with nature. That trees may, in 
general, be recognized as certainly in winter as at other seasons has 
long been known, and little handbooks codifying their winter char- 
acters have appeared in most European countries, and similar keys, 
etc., have appeared several times in our own country, but unfor- 
tunately usually in transient pamphlet form. 
There is now published a neat and accurate little book! dealing 
with the more obviously marked deciduous trees of northeastern 
America, the characteristic traits of which are shown by habit half- 
tones, and the twig details by three-color plates. Professor Sargent 
stands as godfather to the book, which will be an ornament to any 
center table, and should do much to give incentive to those walks in 
winter that the few enjoy so keenly and the many forego because 
they lack a direct object. T.
