76 ALEX. MURRAY ON THE GLACIATION OF NEWFOUNDLAND. 
and westward toward the Atlantic Ocean; whereas, in Newfoundland, the drift, which 
originally came from the north, turned eastwards to overwhelm Newfoundland, whence it 
proceeded eastward to the same termination. 
The above very imperfect sketch of the surface condition of Newfoundland (which 
indeed, was intended simply to accompany the orographical map) may require considerable 
modification when further facts are ascertained, and detailed surveys extended. But its 
imperfections may to some extent be excused, as being the result of exploration through 
a country, forthe greater part, of primeval wilderness, destitute of roads or artificial cuttings 
of any kind, and where the difficulties of procuring intelligible information are very great. I 
have hitherto been unable to discover any clear evidence, either by the presence of fossils or 
otherwise, among the boulder deposits, pointing towards extended intermediate intervals of 
mild or temperate climate, such as have been described as existing in Canada, the Northern 
United States, and notably in Great Britain. Nevertheless, there is reason to anticipate that 
much more light will be thrown upon that and other subjects by future investigation, when 
public works are further advanced, and sections have been cut through the drifts, which, at 
all events, will largely contribute to the extension of our present knowledge. The railway 
now in process of construction will, probably, be of much service in this direction, and 
may be the means of developing many facts with which, in the meantime, we are but vaguely 
acquainted.
