I9II] APPROACHING THE KNOLL 25 
to get once more into the safety limit of land ice on the 
flat, which seemed very narrow in the dark. 
We camped about 8 p.m. Min. temp, for last night 
was - 22 "2"^ and by the evening the temperature had 
dropped to - 28"6°, but there was still a lot of cirro-stratus 
about, which the blizzard doesn't seem to have cleared

miles in all to-day by a good morning march, but an 
afternoon march cut short by a complete loss of all light. 
After lunch we once more found we had overdone our 
easting and had run again into one of the higher pressure 
ridges. We turned north from it and encountered more 
crevasses, but by 2:ig-zagging and sounding in advance 
on a longer trace we succeeded in getting clear of them. 
We had the Knoll before us at the time while there was 
light enough to see it. Our moonlight was, however, all 
but spent, so much of it had been lost in fogs and blizzard 
and bad weather. We were making for rather cast of the
