Overview

Excerpt from Report of a Survey and Exploration of the Coal and Ore Lands Belonging to the Allegheny Coal Company: In Somerset County, Pennsylvania; Accomppanied by Maps, Profiles and Sections By thus ascertaining the position and eleva tions of the beds as found in different parts of the formation, it was a matter for comparison and calculation, to fix the section of the coal-trough in each direction and to compute its depth and other dimensions. Having completed these surveys and levellings for geological purposes, the other objects to be effected on the ground, were to as certain the length and grade of a line of rail-road which might connect the lands of the company with the line of public improvements, by which they might be rendered available; and to measure the thickness of the several mineral deposits, tak ing from each the proper samples for analysis. The field work being thus completed, it became necessary to arrange all the data thus obtained, to plot and reduce the maps, profiles, and sections; and to go through an analysis of coals, iron ores, and limestones, found in the various exposures of the beds.
