being of the type that one would normally refer to the action 

 of glacial ice even in the absence of striations, which would 

 not be preserved on a rock surface where there was no pro- 

 tecting soil cap. In cracks and crevices at the summit there 

 is an abundance of a sandy clay very similar to that found on 

 Orford mountain. This soil contains numerous chips, many 

 of which are of local origin. The summit rock is nearly bare 

 except for the small amount of this soil found in the crevices 

 and no large erratics were noticed. About twenty feet below

the summit two pieces of vein quartz were picked up. On the 

 slopes above the 2000 foot contour several small erratics were 

 found in the soil cover, which consists largely of till. 



Sutton Mountain. — The summit of Sutton Mountain, the 

 highest ridge of the district, is heavily forested, and the sur- 

 face of the ground is nearly all concealed beneath • a moss 

 carpet. Here and there the tops of minor ridges which cross 

 the summit of the main ridge obliquely toward the southeast 

 show rock outcrops. The soil appears to be much the same as 

 on the other ridges of the district. At the summit the writer 

 did not find any erratics, but this cannot be taken as conclusive 

 that they do not occur within a few feet of it since they might 

 easily be concealed by the vegetable growth of the area. A
