LINE OF THE CANADIAN PACIFIC RAILWAY. 381 
At the base of the section (fig. 1), near the level of the river, the 
shales hold calcareous concretionary bands, with bivalve shells charac- 
teristic here of the Cretaceous beds*, which are the only marine fossils 
seen in the section. About 90 feet from the base of the section is a 
bed of coal 3 feet thick, and covered with ashale roof or parting of 2 
feet 6 inches, above which is another coal, 4 feet thick, with a shale 
roof. For about 50 feet above this the cliff is occupied with shales, 
holding several thin coals; and on this rests another bed of coal 3 
feet 10 inches thick with roof of shale 3 feet thick, and over this a 
small coal 10 inches thick. Above this shales again occur, and near 
the top a bed of ferruginous and pebbly sandstone very unequal in 
hardness and texture. In this Mr. Molyneux, an engineer in charge 
of the works, had found some large bones, and on further excavation 
we obtained considerable portions of the skeleton of a large Dinosaur 
believed to. belong to the genus Diclonus of Cope, scattered teeth of 
which occur in the same bed.

The less pure coals in this section are brown coals, composed of 
leaves and vegetable débris compacted together. The better coals, 
including the thicker beds above referred to, are apparently composed 
* Ostrea glabra, Anomia micronema, Corbula subtrigonalis, C. perundata, are 
characteristic, according to Dr. G. M. Dawson. There is also a species of 
Goniobasis.
