 sandstone, which here shows an u*regular lower surface similar to 

 that in Wortman's Ravine near Fultonham. Just above the 

 bridge a very thin seam of coal is shown at the base of the sand-

 shales; and blocks of what is apparently Mercer limestone are 

 visible in the bed of the stream at the bridge. From Elizabeth 

 to Zanesville along the line of the Zanesville and Western Railroad, 

 frequent exposures of the Homewood are seen, many of them show-

 that indicate disconformity.
