Reports Of The First Second And Third Meetings Of The Association Of American Geologists And Naturalists At Philadelphia In 1840 And 1841 And At Boston In 1842 Embracing Its Proceedings And Transactions

Excerpt from Reports of the First, Second, and Third Meetings of the Association of American Geologists and Naturalists, at Philadelphia, in 1840 and 1841, and at Boston in 1842: Embracing Its Proceedings and Transactions Besides the Papers read at the three meetings heretofore held, the present volume includes an account of the proceedings of the Association of American Geologists and Naturalists, from its origin. It affords, therefore, a view not merely of the past labors of the Association, but of its plan and objects, which, it will be observed, differ essentially from those proposed by the other scientific societies of this country. Aiming to promote a closer intercourse between the numerous cultivators of Geology and Natural History throughout the United States, and to lend greater efficiency, by systematic cooperation, to the active exertions now making in these departments of Science, it has imitated in its essential features those Associations of other countries which are seeking, in their several spheres, similar results. It cannot, however, pretend, in the present early stage of its progress, to copy the full and effective organization of some of its distinguished European prototypes. The transactions of the Association have hitherto been confined chiefly to communications, written and oral, of individual members, and to the discussions which these have suggested. It is, however, within the plan of the Society, to procure reports from committees, and individual members, on special subjects of research, several of which have been undertaken, and also on the progress of particular branches.

Henry Darwin Rogers is a familiar figure in the history of American geology, especially as the director of the first state geological surveys of New Jersey and Pennsylvania. Although best remembered for the survey work, Rogers considered his theory of mountain elevation to be his most important scientific legacy. Based on studies of the Appalachian Mountains, Rogers's elevation theory was the first American explanation of the dynamics of elevation. As a study of the Pennsylvania survey, this volume offers new insight into the origin and problems associated with early surveys. As a study of Rogers's life and work, it presents a portrait of a man with strong convictions and dedication and examines the development and application of his ideas.
