WEST VIRGINIA GEOLOGICAL SURVEY. 193 Professor Swartz describes the lithological character ofthe Chemung beds in Maryland as follows (p. 418) : The shale is usually more arenaceous than that of the underly-ing members and hence breaks more frequently into irregular pieces,while the sandstone is not argillaceous and is rarely fissile. The bedsare variously colored, gray, olive-green, yellow, and brown beingcommon tints. Upon weathering many beds become yellowish orbrown and are often stained by iron. Red or brownish-red beds areof frequent occurrence, the percentage of red strata increasing towardthe top of the member. These beds occur at successively lower andlower horizons toward the east until in the sections east of Millstone,they appear near the base of the member. In Morgan and Berkeley Counties, West Virginia, theChemung at the base above the Parkhead Sandstone is c
