acorn, and in general form and expression of the trees. Here a pocket 

 manual of trees will prove a great help, for the specific differences are 

 stated in detail, and supplemented by a picture. Directly the student 

 comes to a decision. The tree before him is, or is not, the one described 

 and pictured on the page. The book is a friend that knows all the trees, and 

 answers questions; that introduces the newcomer to all his tree neighbors. 



This little TREE GUIDE groups together in families the trees one 

 commonly meets in the eastern half of the country. This includes Canada, 

 and the United States that lie east of the Rocky Mountains. With the 

 native species will be found the most important cultivated species brought 

 from other countries, and now quite as familiar to us as our own forest trees. 



To aid the beginner, and to show how few are the traits to learn, when he 

 sets out to make the acquaintance of the tree families, a group of simple 

 keys are presented here. By them, he can quickly distinguish members 

 of the principal groups. Not only to recognize a tree, but to be able to 

 say how we know it, is the help offered first in the keys, then in the succeed- 

 ing pages.
