Sep. 7 Collected in the morning in the Oquossan and at afternoon in the Calgon formation. The Oquossan formation is well exposed along the township line road north of the farm of David Fleming and Anderson the sandstone is abundantly fossiliferous and pure it is not more than six feet thick. A short distance to the east however the formation is quite fossiliferous and the rock more friable. It overlies the Dalhna group in which I saw no fossils. In some places the Dalhna is sym- bolically bedded and in other places is often clodded. The contact between the Dalhna and Oquossan is well shown and while there is no marked unconformity there appears to be a shift or since the lower surface of the Oquossan is uneven
