giniana, and the choke cherry commonly known as P. vir- 

 giniana, is P. nana. For each species only one common name 

 is given, though a few others are found in the index. Choosing 

 from the many common names in use is difficult and the names 

 adopted will not satisfy those who have been using others. 

 Those who have been endeavoring to have Gray Birch used for 

 Betiila populijolia will not be satisfied with American White 

 Birch. And it seems too bad not to use Basswood and Mountain 

 Laurel but to substitute American Linden and Mountain 

 Kalmia. Also it is not to be expected that "common" names will 

 every be commonly used for the 52 species of Crataegus. Those 

 who can distinguish the species will find the scientific names 

 easier than Martha's Vineyard Hawthorn, Marshall's Hawthorn, 

 Caughuawga Hawthorn and so on through the list. In fact the 

 common names are given here apparently for consistency, as at 

 the beginning of the genus it is noted that "many of the specific 

 English names are also unsatisfactory." 



A few errors are due to the printer; Cotinus Adans. instead 

 of Cotinus Adans., Popiilus grandidentaea, instead of P. grandi- 

 dentata, Hamamelis instead of Ilamamelidaceae for the family 

 name, and a few other comparatively unimportant mistakes 

 that will confuse no one. 



But mistakes are few and the matter of classification is only 

 an incidental thing in the book. Its main purpose is to furnish 

 a simple way of becoming familiar with the trees one meets. 

 This the book does very satisfactorily. The book can be used 

 easily by boy and girl scouts and other young people interested 

 in the out-of-doors but is also suitable for students taking 

 courses on trees in college. All the trees native to the north- 

 eastern L^nited States and Southern Canada as well as the more 

 common introduced trees are included. 



The book is attractively bound in red cloth, of a size to fit 

 easily into a coat pocket or handbag and should prove a most 

 valuable companion for those who wish to become familiar 

 with the trees of the roadside and woods.
