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.

Copies of either of the above books will be sent, prepaid, to any address on receipt of the price by the Publishers:

STORER AND LINDSAY'S

Elementary Manual of Chemistry

By F.H. STORER, S.B., A.M., and W.B. LINDSAY, A.B., B.S.

Cloth, 12mo, 453 pages. Illustrated. Price, $1.20

This work is the lineal descendant of the "Manual of Inorganic Chemistry" of Eliot and Storer, and the "Elementary Manual of Chemistry" of Eliot, Storer and Nichols. It is in fact the last named book thoroughly revised, rewritten and enlarged to represent the present condition of chemical knowledge and to meet the demands of American teachers for a class book on Chemistry, at once scientific in statement and clear in method.
