 appeared, but, as already remarked, snow still covered the ice 

 cap above and lay upon the cataracts, and to some extent upon 

 the higher lands adjacent, as will be seen by referring to the 

 photographic illustrations. These particulars, which have little 

 importance in themselves, are introduced here to show the 

 climatic conditions under which these glaciers are formed and 

 maintained. They illustrate the extreme shortness of the season

during which effective wastage is brought to bear upon the 

 glacier proper. The full inference from this, however, should 

 doubtless not be drawn, because the season appears to have been 

 somewhat more than usually severe. 



At the later date, the character and relations of the terminal 

 moraine were fully revealed. On the saddle between the two 

 valleys the moraine was sharply developed as a little ridge lying 

 immediately against the present ice and rising a few feet — rarely 

 the height of a man — above it. In the valleys, the glacier
