ited part of Canada to the south. The course of the stride 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,o 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 ba}'. 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 will be found further inland. 

 Driftwood (mostly spruce) is found almost everywhere, above the 

 highest tides, in a more and more decaj^ed 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 b}^ the long ex- 

 posure to the weather. Judging b}'^ 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 striaj observed at eleven places on the east shore of Lake Win- 

 nipeg vary from S. 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 S. 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 the^^ 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.
