SNOW BLINDNESS. 323 



into near four, — making, with the three times going 

 over it, about twelve. I have not before had so bad 

 a day ; and yet the men could not possibly have 

 brought their sledge through at all. The dogs climb 

 the hummocks with the facility of the chamois mount- 

 ing the Alpine crags. One advantage they possess 

 is, tliat they are not so heavy as the men and do not

 We have reached a most formidable ridge of hum-

 is 12° below zero. 



We set out in the morning with much spirit, but

 with so much labor, is not inspiring. Sleep is our 

 only consolation, and I am glad the temperature is 

 sufficiently high to enable us .to repose without freezr 

 ing. Sleep, that has before drowned many a sorrow 

 for many a weary and care-worn man, has drowned 

 many a one of mine during these past twenty-five 

 days. It is 



" Tired Nature*s sweet restorer," 



among these ice-deserts, even more than elsewhere ; 

 and our sleep is truly the "sleep of the laboring
