Trap dikes have been noted in three instances; one near 71, west of Snody dock, and a second on the shore of South bay near 88. The former appears to be disconnected with any larger eruptive mass and to be a diabasic trap of the common type. The latter may be an offshoot of the neighboring gabbro. There are also two narrow dikes of black igneous rock near 56, in a cliff on South bay, one of which appears to be an offshoot of Fig. 2. Sketch of trap dikes on northwestern shore of South bay, Dresden. the other although the connection is not visible. Fig. 2 illus- trates their relations. The dikes stand vertically and cut the foliation at nearly a right angle. The large one is about 18 inches thick. A short distance further a nearly horizontal band of light, a American journal of science.
