Geographical Surveying.

The article presents an overview of the little treatise, "Geographical Surveying," by F. de Y. Carpenter. Carpenter formerly connected with. the geographical surveys proposes the name Geographical rather than Topographical Surveying, to distinguish the kind of work necessary for covering a large extent of comparatively unexplored country from the slow and detailed surveying which indicates every man's farm and house, as carried on by the Government surveys of Europe. While the former should be based on determinations of primary points no less accurate than the latter, the intermediate details are to be sketched in by methods of approximation, which will present with sufficient accuracy the general physical features of the region surveyed, and the method may therefore be called geographical rather than topographical, as describing the surface of the globe, rather than of limited regions or places.
