ited part of Canada to the south. The course of the strize in sixty-six 
localities between Sherrick’s Mount and Cape Dufferin vary from S. 
45° W. to N. 35° W., many of them are S. 60,° 70,° or 80° W., while 
an equal number are N. 60,° 70,° or 80° W. The bowlder clays abound 
with marine shells. He found abundant evidence that the sea level is 
falling at a comparatively rapid rate in Hudson’s bay. On the islands 
and shores all along the Eastmain coast the raised beaches are very 
conspicuous at all heights up to about three hundred feet, immediately 
near the sea, but, no doubt, higher ones willbe found further inland. 
Driftwood (mostly spruce) is found almost everywhere, above the 
highest tides, in a more and more decayed state the higher above the 
sea, up to a height of at least thirty feet, and in some places up to 
forty and fifty feet, above which it has disappeared by the long ex- 
posure to the weather. Judging by the rate of decay of spruce-wood 
in this climate its preservation in large quantities, during an elevation 
of the land, or rather a fall in the water, to the extent of thirty feet, 
would indicate a change in the relative level of the sea, amounting to 
perhaps between five and ten feet in a century. 
The striz observed at eleven places on the east shore of Lake Win- 
nipeg vary from 8. 15° W to S. 45° W.; at thirty-four places along the 
boat route from Lake Winnipeg to Hudson’s bay, they vary from S. 
50° W. to S. 20° E.; and at twenty-one places along the Nelson river, 
from Great Playgreen lake downward, they vary from 8. 25° W. to S. 
80° W. The bearings refer to the magnetic meridian. 
G. F. Mathew found the course of the grooves and scratches on the 
rocks in the southern counties of New Brunswick having both south- 
easterly and southwesterly bearings. A southeasterly course is most 
prevalent in the western part of Charlotte county, and a southwesterly 
course most prevalent in the valleys east and northeast of St. John. 
These two general courses, as well as the intermediate ones, are con- 
trolled by the contour of the surface of the land in the several districts 
where they occur; for, as a general rule, the furrows conform to the di- 
rection of the river valleys, or at least are influenced in their course by 
these depressions.
