To quickly assess the difficulty of the text, read a short excerpt:
2. These deposits occupy deep basins, which have been eroded in Lower Carbon- iferous shale or limestone or in the hard, slightly calcareous sandstones of the Knox group. In at least two localities branches protrude from the main body into drains or ravines, so that the horizontal plan resembles somewhat the splash made by throwing soft mud against a wall. 3. The character of the deposit is wholly independent of the rocks on which it rests. 4. The gypsum occurs in irregular masses, incased in r...ed marly clay, which penetrates the gypsum to a variable distance; there is less of this clay in the eastern basins than at Saltville. 5. At a variable depth salt occurs with the gypsum, and this salt contains very little of iodides or bromides. 6. Blue clay overlies the gypsum at all localities yet examined. 7. No fossils of any sort have been found 'thus far in the gypsum, its incasing red clay, or in the overlying blue clay; but just west from Saltville a conglomerate cemented by gypsum occurs, in which remains of Mastodon have been found ; this overlies the blue clay and incloses many fragments of both blue and red clay.
