BOOKS ON THE NATIVE TREES. 



Quite naturally the young forester is interested in books 

 that enable him to determine exactly the classification of the 

 trees he finds in his work in the forests. While this can be 

 done very well in most cases by the use of the manuals given 

 above, it is often desirable to make a more critical study of 

 certain species than can be done without a resort to the books 

 that treat of trees alone, in order that he may note their varia- 

 tions and peculiarities more closely. 



Sargent's Silva of North America (1891 to 1902) in four- 

 teen quarto volumes is the finest work of its kind ever pub- 

 lished in any country. Every species is figured in life size as to 

 leaves, flowers and fruits, accompanied by very full descriptions. 

 It is the "court of last resort" in all questions as to the identity 

 of our native trees. 



Sargent's Manual of the Trees of North America (1905) is 

 a compendium of the preceding, in one octavo volume, and is 

 almost as useful for identifying the trees as the larger and more 

 cumbersome work. 



Britton's North American Trees (1908) is much like Sar- 

 gent's Manual, but is considerably less technical. Both include all 

 our native species throughout the country, so they can be used 

 from Labrador to Arizona, and from Florida to British Col- 

 umbia.
