"Thermometer went below -40° last night," Scott wrote, "it was desperately cold for us, but we had a fair night. I decided to slightly increase food; the effect is undoubtedly good. Started marching in -32° with a slight north-westerly breeze -- blighting. Many cold feet this morning; long time over foot gear, but we are earlier. Shall camp earlier and get the chance of a good night, if not the reality. Things must be critical till we reach the depot, and the more I think of matters, the more I anticipate their remaining so after that event. Only 24 1/2 miles from the depot. The sun shines brightly, but there is little warmth in it. There is no doubt the middle of the Barrier is a pretty awful locality."
