East Arm of Bonne Bay.
and almost into Brett Bay.
arm. My description of it then tallies and what are so now. As one looks at the head land that has the East arm tides in with side of it, has the strata dipping also to the southeast just as I drew it in my note book of 1900. The north shore of East arm is therefore made of [?] Diffen Cambrian and Beedmantown strata. These strata come in again along the north of East Arm near Reedys farm.
Dunton and Californias came up Deer Brook and finally up to 1600
but above the sea and saw no other rocks than the L.C. Our granite is visible from at the top of the hill up to 2000 feet and the topography is not one of granite, Dunton says it is all L.C. As the slope of the mountain is about that of the L.C., there may be no great thickness of L.C. to be added to the section. Yet there may be several hundred feet of strata here. Dunton says that only of the strata seen are quartzite with some sandy shales. It seems best that one should say that at least 500 feet L.C. may come in between the seam base and the granite, and it may be that the thickness is even a good deal thicker.
In the afternoon launched up East Arm but the tide was at its height and could not get out any where to see the L.C. as the rocks in most places make no tender showing the dips into the water. On the north shore of Brett Bay near the point into this bay there is a thick light colored quartzite that I take to be the base of the Diffen Cambrian = Beedmantown. These rocks strike across the bay into the headland that makes the land between East and Brett Bays. In this peninsula there is away 1900 feet of old miles including the above mentioned quartzite below, are probably Beedmantown. If any in Diffen Cambrian it is got to be proven. Later Dunton will visit the place again when the tide is low to see the contact between the L. Cambria and Beedmantown.
