bedded, or conglomeratic. Next come dark crystallines of the gabbro 

 type, then pink granites, then buff limestones. A few moments' 

 search revealed abundant striae, not only on the limestones but on 

 the crystallines as well. A quarter of an hour's walk along the beach 

 showed scores of boulders so definitely striated that any one of them 

 would settle the question of their glacial origin. 



It next remains to inquire into the age of the ice. A careful 

 search was made around the whole border of the island, but the base 

 of the ice was nowhere visible. It cannot be denied, then, that some

of the boulders might have come from beneath, but many, and prob- 

 ably most, of them came from the few feet of till that lies on top of 

 the ice. Several were seen with ice immediately below them in the 

 face of the cHff. Consequently there seems no escape from the con- 

 clusion that the ice is of equal or greater age than the glacial till that 

 lies above it. 



Two boulders, approximately ten and fifteen inches in diameter, 

 were found imbedded in the ice itself. The former lay in the lower 

 portion of a few feet of ice exposed in the cHff ; the latter, thirty feet 

 back from the face of the cliff, in the vertical wall of clear ice that
