August 9. Portland Creek.

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
