pressive in colour, and appearing so early in the season that 

 they are neither looked for nor noticed. 



That trees have a very well-defined preference as to the 

 character of the soils in which they grow most readily and 

 healthily is a generalization that is unfamiliar to many, and 

 that their surroundings and kind of exposure affect their 

 growth to a large degree will also be a new idea to some. 



All these lessons, and a great many more, will be found in 

 detail in the pages of this beautiful book, and they are taught 

 in language which will be readily intelligible to all, while the 

 concise descriptions of the different trees, and of their parts, 

 taken in connection with the profuse and excellent illustrations, 

 will make easy and attractive the identification of all kinds or- 

 dinarily met with in Eastern North America.
