Geology of the City of New York

Abstract

THIS general treatise on the underlying structure of the city of New York and its immediate surroundings appears to be the amplification of a shorter work on the same subject, printed privately for the author. Its outlook is local, and, as the interpolated “Class Directions” indicate, it is intended primarily for use in the instruction of the inhabitants of the great city. It is compiled from various sources, which are duly acknowledged, and contains, besides, some original observations, but these are not sufficiently important or numerous to appeal to the wider circle of geologists who have no particular interest in the locality. In many passages it emphasises the transformation wrought by man on the original aspect of the country, in deference, no doubt, to the naive astonishment with which the average town-dweller receives such information.
