Apgar's Trees of the Northern United States 



Their Study, Description, and Determination. For the use of 



Schools and Private Students. By AUSTIN C. APGAR. 



Cloth, I2mo, 224 pages. Copiously Illustrated . . . $1 .00 



This work has been prepared as an accessory to the study of Botany, 

 and to assist and encourage teachers in introducing into their classes 

 instruction in Nature Study. The trees of our forests, lawns, yards, 

 orchards, streets, borders and parks afford a most favorable and fruitful 

 field for the purposes of such study. They are real objects of nature, 

 easily accessible, and of such a character as to admit of being studied at 

 all seasons and in all localities. Besides, the subject is one of general 

 and increasing interest, and one that can be taught successfully by those 

 who have had no regular scientific training.
