Key to the Wild and Commonly Cultivated Trees of the North- 

 eastern United States and Adjacent Canada. By J. F. Collins 

 and H. W. Preston. New York. 1912. Pp. 184. Price 40 

 cents. 



This book is to serve as a guide for the layman who wishes to 

 distinguish the trees. It is based primarily upon leaf characters, 

 to which the authors adhere consistently throughout, using other 

 characters as seldom as possible, though in some cases their means 

 of separation ("ear marks") would be easier for the unscientific 

 reader. The key is well arranged, well balanced in detail, free 

 from technical terms, etc., very satisfactory to the user in the 

 directions with which he can determine the species. 



The book deals with 211 species, illustrated by 279 cuts of 

 leaves and bark. It is of handy pocket style and should prove a 

 popular guide.
