July 14. Clam Bank Cove and Smith's Point. On the other hand there are chucks I didn't take but these are angular. For the next quarter mile the strata is parallel to the coast facing up along these rocks. As that forms a thickness of 200 feet of this conformative sandstone is exposed in the cliff and in ledges just of stone. This is the basal conformations of the Cretician and from here on with the strata cuts across the line or their succeeding dip layers are exposed, repeating the sections just seen and continuing for a total thickness of 1000 feet of brown Cretician stratum extending to the mouth of Trout Brook at Three Road Point, a distance I put at 2 1/2 miles. The Cretician section is as follows, beginning at the base: - 200 feet. Heavy bedded, much cross-bedded sandstone and conglomerate. Dark red. 400 feet. shale and thin Italy sandstone mostly red but over-set with greenish gray bands, grading into the following. Banded with small cracks and ripple marks. 100 feet. Greenish gray sandy shale and Italy sandstone with some interbedded clay bands which are replete with fossils for fun kinds. A Spirifer is most common and a small ostracoid. Other layers have Leperditia and other pelecypods, except the Camarocinines. Bearing very fine of the thin layers of Italy sandstone is ripple marked. Many layers are cemented with flinty material. 300 feet. Variegated beds of sandy shale and thin shaly sands.
