Ms. Cambrian From the threadled limestone underneath this bed of limestone conglomerate we collected a number of small Lingulas and many fragments of trilobites. These preserved ones came from a small hole about 4 feet long by 18 inches thick in the middle of li. cong. All the other specimens came from the thick about my right, thick white shale underneath before. Masses of threadeds underneath the heavy zone of li. cong. that I photographed me as fast blocks of Cambria li. dropped into the Corr Head conglomerate. In the quarter mile of the outer side of the peninsula examined this afternoon there is at the tip a heavy zone of li. cong. from 15 to 20 feet thick and below are the threadeds of Cambria li. anywhere from 10 to 20 feet thick. all of the conglomerate here is made of Upper Cambrian material. See any photo of these places. For many places the Cambrian in small cones is included in a bent and even crumpled condition. This deformation must have taken place before the pieces were included in the conglomerate and after Cam- of these bent strata brian time. The date of deformation was probably post Tattle Head. Even in the Phyllographus beds there are conglomerate zones and while these are of small pebbles (inches across) and not just yet they are li. cong. not un- like those of other parts of the Corr Head conglomerate. They must be of intraformational character. The whole of the strata of the peninsula are distinctly bedded and we can't fail to note the dips. When we comes upon the threadeds zones of either the Phyllographus or Cambrian, the impression left is that they must be regular de- deposited posits between the conglomerate zones. Yet the fossils secured are entirely not of keeping with the design in which they seem for Reedmanutons and Upper cambrian fossils cannot be living in post Tattle Head time. See elsewhere noted. Several times there many large holes of intraformational conglomerate included in the Corr Head conglomerate. These are not of the first little type.
