Not illustrated. 1880 edition. Excerpt: ...on the land of Mr. Taylor, and some of the layers make a very excellent building stone. (No. 6) is a bluish, very argillaceous shale, which contains considerable iron, thus causing it to weather to a rusty color on exposure. The Sharon coal has here, according to Mr. Chance, an elevation of 1068 feet above tide. About 2k miles south-west from Sharon, in Ohio, the coal is extensively mined by the Brookfield company. As the rock exposures along a little stream which puts into Big Yankee run are very good, I will give the section here for reference and comparison. Passing down the run from the coal slope past Whittaker's Falls the section is as follows: Fig. 65. Whittaker Falls Section; Hickory T. 1. Sharon Coal, 4' 2. Concealed, 10' 3.

It is composed of two distinctly different rocks, though they are in immediate contact. The upper half of the stratum is a fine-grained sandstone of almost snowy whiteness; the lower half is a genuine conglomerate, being composed largely of quartz pebbles loosely cemented together in a matrix of coarse grayish-brown sand. The pebbles are mostly angular, ranging in size from a pea to a hickory nut; most of them are ovoid, but occasionally we see some that are flattened. The upper surface of No. 3 here forms the surface rock, and its top is planed off perfectly smooth and striated by glacial action; scratches and grooves running nearly south.
