The following treatise has been prepared in accordance with the request of a large number of teachers, who desired to introduce the study of Geology: into our higher schools. The work is designed to be strictly elementary, and hence does not embrace protracted discussions on the more abstruse and undetermined problems of theoretical geology; it aims to engage the interest of the pupil in the facts of the science.

The authorities for the facts cited are principally Lyell, Murchison, Buckland, Ansted, Agassiz, Hitchcock, Dana, and the State Geological Surveys, particularly that of Professor Hall of New York.

The engravings were executed by Professor Brainerd, and in some instances the subjects were sketched from nature by him.

An analytical table of contents seemed to the author preferable, for the purposes of examination
