165 August 18-1918 Harkers Bay, South shore these then bedded sometimes with thin gms of flint to almost black shale. I go across the strike for 80 yards = about 12 feet. In the middle of this at 70 Gone I find Olenellus beds in the very thin sandstone into bedded with the dark shales. Trilobes occur in the shales along with a very rare fragment of white spongia, i.e., a Patumina. Therefore I now know that I am in the Lower Cambrian. It is then about 100 yards crossing to another point. In this interval there are lamination bedded sandstone and very few shale gones. In the latter I again saw fragments of Olenellus. At a dip of 7 deg, the thickness in 36 feet. At 40 = 21 feet. At the last mentioned point I enter into another clay core in fault of which I cannot see more than the surface ground at this side. occurs a low rocky island, the only fault exposure about 25 feet of heavy and ribbon They are reddest with some bright discoloring my eyes/163. then bedded fine grained almost white sandstone that overthrusts pinkish. On the near far side of this clay core one sees no exposures but I estimate there are here un- exposed about 60 feet of sediment. I get by estimating it in 300 feet across the dip to the other side of the core and at 10 degrees dip (has steepened since) the (= about 35 feet corrected). thickens away from it about 60 feet. Later learn that the dip is to fault information 6. At the next point mostly that crosses the headland to the core with the two classification that are a part of systematic. islands in a little about 20 feet long bedded white quartzite. The boulders are of the size of pebbles. Kelomina ferns are common to carry some clays and stones. Here is a half sandstone one can see fragments of Olenellus but they are much proportioned. On this point the shales are much cross bedded giving the appearance of undulations. Then another clay core with Carter north emptying into it. Here are small island on the strike or in thickness of strata is crossed. At the north near exposed sandstone but small Olerlithus (see specimen).
