To quickly assess the difficulty of the text, read a short excerpt:
The drift affords more than the usual proportion of sand and gravel. A water-bear- ing layer occurs within sixteen feet of the surface, a sand and gravel bed ten feet in thickness was encountered at forty feet below the surface, and the superficial deposits terminate in a bed of sand and coarse gravel which is also water-bearing. The coal measures are not represented in the above section, although the utmost diligence was exercised in the search for the slightest clue to their presence. Coal is... mined at Summit, about eight miles north of the college, and 165 feet of shales and clays represent the Upper Carboniferous series at Nevada, ten miles east; while at Boone, twelve miles west, 266 feet of sandstones and shales may be referred to this formation. It is reported that coal was found when sinking the well at the Experiment station, about a quarter of a mile northeast of the deep well. While this is altogether possible, and even probable, it seems reasonably certain from other data at hand that if coal in situ does really exist at that point it can be little more than a detached basin or "pocket," of very limited area.
