IN AUDUBON'S LABRADOR 



vated, but it also seems probable that the sea 

 once entered more deeply than it does now, for 

 the raised beaches extend back some distance 

 up the valley. Some of the beaches are com- 

 posed of great flat blocks of sandstone which 

 are but little rounded; on other beaches at 

 higher or lower levels the cobbles are more 

 nearly spherical. This would point to a differ- 

 ence in the rate of elevation, as some of the 

 beaches must have been hurried out of reach 

 of the sea before the waves could finish their 

 work of making the perfect cobble-stone. On 

 the western side of the entrance to the valley 

 the raised beaches, six or seven in number, are 

 more distinct, and the cobbles are smaller and 

 more perfect, showing, as might be expected, 

 stronger wave-action than on the more pro- 

 tected eastern side. On these beaches I found a 

 few granitic cobbles among those of sandstone. 



The bed of the valley, in which the streams 

 have meandered back and forth, is a flat, sandy 

 plain well covered with vegetation. In one 

 place is a small oblong mesa, perhaps forty feet 

 high, with steep sides, which has escaped the 

 erosion of the river. 



Much as I wished for a geologist to show
