OLD MORAINE AT POSSESSION BAY. 717 



dently advanced from the south, for the mass 

 had been pushed steeply up on the southern 

 side, and retained so sharp an inclination on 

 that face that but little vegetation had accu- 

 mulated upon it. The northern side, on the 

 contrary, was covered with soil and overgrown ; 

 it sloped gently off, pebbles and larger 

 stones being scattered beyond it. The pebbles 

 and boulders of this moraine were polished, 

 scratched, and grooved, and bore, in short, all 

 the usual marks of glacial action. Agassiz 

 was naturally delighted with this discovery. 

 It was a new link in the chain of evidence, 

 showing that the drift phenomena are con- 

 nected at the south as well as at the north 

 with the action of ice, and that the frozen 

 Arctic and Antarctic fields are but remnants 

 of a sheet of ice, which has retreated from the 

 temperate zones of both hemispheres to the 

 polar regions. The party pushed on beyond 

 the moraine to a hill of considerable height, 

 which gave a fine view of the country toward 

 Mount Aymon and the so-called Asses' Ears. 

 They brought back a variety of game, but 

 their most interesting scientific acquisitions 

 were boulders from the moraine scored with 

 glacial characters, and shells from the salt- 

 pool.
