pebbles, underlies the gray and drab bowlder clay, which is overlaid 
by gravel, sand, and gravelly earth. Marine shells were collected 
along this river from the Grand Rapids, and along the Missinibi from 
near Round bay, all the way to Moose factory. ,They appear to be | 
derived from a pebbly, drab clay, associated with the bowlder drift. 
The greatest elevation above the sea at which they were collected, is 
about 300 feet, but they were found along the Kenogami, a branch of 
Albany river, at the height of 450 feet. Among the fossils collected 
are, Rhynchonella psittacea, Leda truncata, L. pernula, Cardium 
islandicum, Tellina grenlandica, Macoma sabulosa, Saxicava arctica, 
Balanus crenatus, Mya arenaria, M. truncata, Mytilus edulis, and 
Buccinum undatum. 
Milne and Murray* found the drift on Newfoundland containing 
sbells similar to those still living in the surrounding sea, as well as 
striated angular stones, terraces, and raised beaches tending to show 
that Newfoundland was at no very remote period below the present 
level of the sea. The surface of the rocks is often roundly smoothed 
and striated as if produced by coast-ice acting in a rising area.
