course,’ the ice producing them having moved down the slopo 
mentioned in the St. Lawence valley from the north. But 
south of the water-shed, separating the waters of the 
Ottawa River from those of the great lakes, the striz 
are found to swerve more to the south and south-west. Im- 
mediately north of lakes Huron and Superior they have a 
south-westerly trend,’ and this appears to be the normal 
course along the border of the Archean Area to Lake of 
the Woods, and as far as Lake Winnipeg, in the latter 
region, perhaps, having a little more westing.’ On the 
east side of Hudson Bay, striz have been observed by Dr. 
R. Bell‘ and Mr, A. P. Low of the Geol. Survey (report of 
latter gentleman not yet published) to run westwardly into 
its basin mainly following the valleys. On islands in the 
northern part of Hudson Bay, Dr. Bell found strie indicating 
a northward fiow of ice ;’ while at Hudson Straits, the course 
appears to have been north-east and east.® 
On the east and south-east coast of Labrador there is evi- 
dence, according to Packard, that the ice followed the valleys 
and nearest slopes to the sea.’ 
It would seem therefore, that there was an outward flow 
of ice radially around the margin of the great Archean 
Area. Whether the whole area was occupied by glaciers 
moving from the centre towards the circumference, or the 
central portion was largely covered with masses of snow
