80. Deer Brook Bay is at the eastern end of East Arm. What Shore calls Deer Brook at the western point seems to have no name. Evidently Richardson's section was measured at the eastern end of East Arm and not in the center of the arms extending east. In the late afternoon and evening Duncan went back along the north shore to see for contact between the L.C. and Bear Mountain. On the latter he found a very irregular interval before he came upon the L. Cambrian. They two trails leads. My notes are continued on page 84. Duncan climbed Miller Brook and at 350 feet above the sea or here still in the L.C. quartzites. Here the strata dipped about 20° nearly south. They then climbed up the east to an altitude of 1600 feet and where still in the same quartzites. From here they could plainly see the Cambrian all the way to the tops of the hills.
