At Mile End the top of the Trenton glaciation. On it rests about one foot of glacial material and then follows marine sand with glacial material full of Saxica- ra, Astarte and Mya truncata. Large gastropods also occur, Fulgur like. There are massive Terraces of tr 600 feet or that the sea above time in Cham- plain time was 600 feet deep. This is an important matter in paleography and also in regard to the removal of these marine deposits. Left Montreal at 8.05 and got to Ottawa at 11 P.M. Stopping at the Russell House.
