August 9. Portland Creek. 132 one block of thin-bedded finely Table Head limestone that is dipping 50°S, 60°E is at least 225 long running into the sea and about 100 feet thick. All of the li. crgyl seen this afternoon appear to be ground up in the main Table Head limestone. In general the pieces are under three inches across though others may be up to 18 inches long and an inch in thickness, in this mass of angular pieces lie scattered far apart small blocks angular up to 2 feet across of a nicely white kid-sege like li. It is astonish- ing to see the uniformity of the material, nine-tenths of which appear to be of Table Head derivation, and the rest majority of it ground up to small pieces. There certainly is some Chazy fragmental in it. Nowhere did we see the slightest indication of bedding in the ground up material, and bedding was not seen in the large blocks one of which stood nearly vertical. This bedding is that of the blocks before fragmenting. About 2½ miles north of Portland Creek we saw two cliffs developed elevated beaches. The lower one stood about 35 feet above the sea and had a width of about 20 feet. Back of it was a cliff 15 feet high so that the upper beach was about 50 feet above sea level. For 2 miles north of Daniels Headon are the cliffs all of fine-grained material. Granite boulders are large and It would seem that the fault beyond at Lown Head con- tributes to the crest of Parsons Pond Hill and Portland Hill. After supper we went out to see the li. crgyl of Daniels Harbor than those of Portland Creek and in It is a more rocky crgyl made up in the main of Chazy pieces as the may be to 6 or 8 feet across and masses of Table Head thin-bedded masses up to 30 feet long. The exposure is about
