PREFACE. 



"C , if you and I were to meet -a man on the 



street and ask him his name, he could tell us. I wish a 

 tree could do as much. Here are splendid specimens all 

 around us, and I don't know one of them." 



" Get a book that will help you." 



" I cannot find such a book. I can find no book 

 which, in simple fashion, will so describe the tree, from 

 its foliage and bark and style, that I can recognize it." 



" Then I will make one for you." 



The trees described in the following pages include 

 all the native trees of Canada and the Northern United 

 States east of the Mississippi River. Mention has also 

 been made of the more important of the introduced and 

 naturalized species. The work has been so arranged that 

 any given specimen can be readily found by help of the 

 GUIDE on page i. 



My chief authority for the geographical distribution 

 of the species is Sargent's report in the Tenth Census
