To quickly assess the difficulty of the text, read a short excerpt:
At the outcrop the vein is scarcely a foot thick, but at the depth of thirty feet it is enlarged to nine feet, descending nearly vertically. Thus, at the rate at which it continued to increase, in the short depth proved, it was anticipated the mass beneath must acquire enormous magnitude. Several lateral branches pass upwards from the main vein, both in its vertical and longitudinal direction, all apparently ramifying from a voluminous mass below. Strictly speaking, the solid bitumen was in no ...case enclosed between walls, but seemed rather to occupy fissures in the ancient rocks, and cavities larger than we could venture to speculate upon. The outcrop was easily traced about two hundred to three hundred yards, but beyond this no effort had been made to prove the vein-. Miserably inadequate as was the system adopted for the extrac- tion of this coal, we could not but infer that an enormous amount of this substance might very cheaply be obtained. Under the management then going on, all the water, as well as the materials, was hoisted up by hand, in small vessels, and conveyed to a distance by a gang of negroes ; economy in labour being in no respect consulted, and no kind of machinery, not even a windlass or wheelbarrow, was employed in the so called mine, i In regard to the arrangement of the matter of the vein itself, we noted, that the asphaltum was disposed in horizontal laminae, whatever might be the inclination of the veins or branches; thus essentially differing from the usual character of coal seams, whose lamination is always parallel to the direction of the strata.
