 snow had been blown away, and it seemed 

 therefore probable that all were alike, — snow- 

 covered pinnacles of rock.

 till a port was reached where a new one could 

 be suppHed. The detention, had it not been 

 for such a cause, was welcome to the scientific 

 party. Agassiz found the rounded and mou- 

 tonnees surfaces and the general modeling of 

 the outlines of ice no less marked here than

The country above Mayne's Harbor was 

 pretty, though somewhat barren. Beyond the
