west elongation. North of Cape Negro is an esker two miles 

 long with the main highway running on the crest. It runs 

 across a swamp in a north-south direction, turning S 10 W 

 at the southern end. In one place the ridge disappears for 

 50 feet, and in another it divides to pass around a kettle hole 

 100 feet long and 60 feet wide. At the south end it apparently 

 expands into a poorly defined gravel plain. Another esker 

 connects Cape Negro with the Blanche peninsula. Here 

 again the road follows the esker ridge for three-quarters of a 

 mile. The esker is 5 to 25 feet high and 50 to 100 feet broad. 

 Northwest of Baccaro Point is an esker crossing a marsh, 

 with a road on its top. This esker runs in a southerly direc- 

 tion for half a mile with a height of 20 feet and a width of 

 60 feet. 



Everywhere in Shelburne County boulders are to be found. 

 The largest are west of Shelburne. At the side of the railroad 

 here, may be seen granite boulders 35 feet long, 25 feet broad 

 and 20 feet high. This size of boulder is not infrequent, but 

 more abundant are somewhat smaller ones, 10 to 25 feet long, 

 lying not far apart, yet not forming a boulder moraine. To 

 emphasize the size of the boulders, it may be stated that all 

 the granite for the two story granite post-office building in 

 Shelburne was quarried from a single one. 



In the region between Barrington and Roseway, which 

 was burned over in August 1911, boulders about two feet in 

 length are everywhere scattered over the surface, as abund- 

 antly on the eskers as elsewhere. They are composed prin- 

 cipally of the kind of rock found nearby. It is everywhere 

 characteristic of these boulders to have rounded surfaces, 

 and yet not to evidence distant transportation. Only one 

 boulder was found of a rock not represented in the area by a 

 closely allied type. This was a diorite found north of Gun- 

 ning Cove. 



The direction of ice movement in the region was, judging 

 from the striae, in a S 10 E direction in general. The striae
