A series of courses in natural history will be given by Harvard men during July at Bayville, Lineken Bay, Maine. The object of the work will be to teach the elements of natural history by observation in the field and laboratory under trained observers, and to furnish opportunity for more extended work.

The following courses will be given:

Geology--Mr. A. W. Grabau 3G., instructor in Geology at Rensselaer Polytechnic Institute, N. Y.

Zoology--Mr. Freeland Howe, Jr., 2G.

Botany--Mr. C. E. Preston 1G., assistant in botany.
