THE AMERICAN NATURE SERIES

In the hope of doing something toward furnishing a series where the nature-lover can surely find a readable book of high authority, the publishers of the American Science Series have begun the publication of the American Nature Series. It is the intention that in its own way, the new series shall stand on a par with its famous predecessor.

The primary object of the new series is to answer questions which the contemplation of Nature is constantly arousing in the mind of the unscientific intelligent person. But a collateral object will be to give some intelligent notion of the "causes of things."

While the cooeperation of foreign scholars will not be declined, the books will be under the guarantee of American experts, and generally from the American point of view; and where material crowds space, preference will be given to American facts over others of not more than equal interest.

The series will be in six divisions:

I. NATURAL HISTORY

This division will consist of two sections.

=Section A. A large popular Natural History= in several volumes, with the topics treated in due proportion, by authors of unquestioned authority. 8vo. 7-1/2x10-1/4 in.

The books so far publisht in this section are:

=FISHES=, by DAVID STARR JORDAN, President of the Leland Stanford Junior University. $6.00 net; carriage extra.

=AMERICAN INSECTS=, by VERNON L. KELLOGG, Professor in the Leland Stanford Junior University. $5.00 net; carriage extra. Arranged for are:
