108 1107 1108 1109 6:24:7: C The point forming the southeast shore of the little gove in central 6:24:7 is composed of a series of better limestones of which there are exposed about 60 feet. These limestones show a strike swinging around from N. 25 degrees west to N. 65 degrees west in traveling northwestwardly, and continuing a few yards to the west we find some gray shales striking East-west and dipping North. The shales dip under the limestones, in case as seems probable, there is no fault disturbing the relations. The precise contact between shales and limestones does not show, the interval being covered, ex- certing for the outcrop of an intrusive diabase sill (1193) West of the little shale outcrop mentioned we find an abrupt change in the strike which indicates a fault trending N. 20 degrees west. The shales were nearly flat, striking N. 20 degrees west and showing an anticline with dips of 10 degrees to both east and west. This anticline is local and- arently confined to the vicinity of the fault plane as the shales in the southeast corner of the gove strike N. 35 degrees east and dip east 15 degrees, and on the west side of the gove the shales again dip N. 35 degrees East and are flat. The gove appears to be a triangular wedge of shale cut off on both east and west by a fault plane. The specimen 1092
