104 Quadrille Ruled Form. John C Moore Corporation, Rochester, N. Y. Binder and holes in leaves, each Patented 1906 July 1, 05 In the little cove to northwest of the house we saw black some blue slated shales appear east of the little stream. The strike is here N. 10° W., dip 35° N.E. The shale are of a dark blue color with a few gray bands and are black bedded & splintered. An Outglenas was observed. At the brook in the southwest corner of the cove a very coarse diorite intrusion is found. Northerward shales form the west shore of the cove. 100 yards north of the Brook the strike is N. 5° E., dip 34°, E. This strike is continued northerward to the n.w. corner of the cove, just back of the west shore there runs a gabbro- diorite intrusion in places moderately coarse grained, elsewhere more course and coming to the shore in places. It is not more than 25 feet thick. On the shore in N.W. 5.54.4 appear some very dark black bedded shales occasionally with dark fragments & at first sight resembling basic tuff. These are interstratified with gray phyllite lined shales & with ordinary blue splintery shales, a black (SPh) layer of tuff with rounded thin shale fragments as far as I can also appears. In the gage in the little cove bordering 5.54.4 - SPh occur outcrops of gabbro trending N.35° W on the east contact = The point extending from 176?
