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.
