levels, the outline of the glaciated surfaces pointing to 

 an eastward movement, the composition of the drift, and 

 also from the fact that the long depression of Fox's 

 Channel and the Strait runs from the northwestward 

 towards the southeast, and that this great channel or sub- 

 merged valley deepens as it goes, terminating in the 

 Atlantic Ocean. Glaciers are said to exist on the shores 

 of Fox's Channel, and they may send down the flat-top- 

 ped icebergs which float eastward through the lower part 

 of Hudson's Strait into the Atlantic. During the drift 

 period the glacier of the bed of Hudson's Strait was 

 probably joined by a contribution from the ice which 

 appears to have occupied the site of Hudson's Bay, and 

 by another, also from the southward, coming down the 

 valley of the Koksok River, and its continuation in the 

 bottom of Ungava Bay. The united glacier still moved 

 eastward round Cape Chudleigh into the Atlantic." 



Distribution of Bowlders. — The whole surface of the 

 country is strewn thickly with bowlders. After ascending 

 five or six hundred feet above the level of the sea, and 

 penetrating into the interior, their presence is especially 

 marked. Near the shore they are rarely seen, being 

 covered by vegetation. We must look for them about 

 the edges of ponds and along the banks of the rivers^ 

 and especially in raised beaches. I am also inclined to 

 think that their abundance near the coast is greatly less- 

 ened by their having been carried off by shore-ice into 

 the sea, and there rearranged into submarine beaches. 



No loose, single bowlders scattered over the surface 

 of the country were seen on the coast from Mecatina to 

 Square Island. They only occurred as stated above, 

 along the courses of rivers, by ponds, and rearranged
