Lunch camp, Height 9,950. Last depot. During the night the air cleared entirely and the sun shone in a perfectly clear sky. The light wind had dropped and the temperature fallen to -25º, minimum -27º. I guessed this meant a hard pull, and guessed right. The surface was terrible, but for 4 3/4 hours yielded 6 miles (geo.). We were all pretty well done at camping, and here we leave our last depot – only four days’ food and a sundry or two. The load is now very light, but I fear that the friction will not be greatly reduced.
