cycle, all the Cleonian and about the same thickness of Chrieman as near Clifton. The Chrieman has here a thickmess if 120 feet. Fossils hule are scarce until within about 40 feet of the top where mollusca and brachiopods are fairly abundant. This horizon maybe called the Entrelign beds due to the abundance of this shale. It however appears probable that this shale occurs throughout and of the Chrieman. The coal horizon of the Chrieman is at the top though species are found throughout particularly cup corals. A small celled Springfosa is also found at the base of the Chrieman.
