By our excursions to the depots we had gained a great deal. We had not only carried a large amount of provisions toward the south, but we had also gained valuable experience. That was worth more and was to be of value to us on our final advance to the Pole.
The lowest temperature we had observed on these depot excursions was -50° Centigrade. The fact that it was still summer when we recorded this temperature warned us to see that our equipment was in good condition. We also realized that our heavy sleds were too unwieldy and that they could easily be made much lighter. This criticism was equally applicable to the greater part of our equipment.
Several days before the disappearance of the sun were devoted to hunting seal. The total weight of the seals killed amounted to 132,000 pounds. We therefore had ample provisions for ourselves as well as for our 115 dogs.
Our next problem was to supply a protective roof for our dogs. We had brought with us ten large tents in which sixteen men could easily find room. They were set up on the Ice Barrier; the snow was then dug out to a depth of six and a half feet inside the tents, so that each dog hut was nearly twenty feet high. The diameter of a dog hut on the ground was sixteen feet. We made these huts spacious so that they might be as airy as possible, and thus avert the frost which is so injurious to dogs. Our purpose was entirely attained, for even in the severest weather no dogs were frozen. The tents were always warm and comfortable. Twelve dogs were housed in each, and every man had to take care of his own pack.
After we had seen to the wants of the dogs we could then think of ourselves. As early as April the house was entirely covered by snow. In this newly drifted snow, passageways were dug connecting directly with the dog huts. Ample room was thus at our disposal without the need on our part of furnishing building material. We had workshops, a blacksmith shop, a room for sewing, one for packing, a storage room for coal, wood, and oil, a room for regular baths and one for steam baths. The winter might be as cold and stormy as it would; it could do us no harm.
On April 21st the sun disappeared and the longest night began which had ever been experienced by man in the Antarctic. We did not need to fear the long night, for we were well equipped with provisions for years and had a comfortable, well-ventilated, well-situated and protected house. In addition we had our splendid bathroom where we could take a bath every week. It really was a veritable sanatorium.
After these arrangements had been completed we began preparations for the main advance in the following spring. We had to improve our equipment and make it lighter. We discarded all our sleds, for they were too heavy and unwieldy for the smooth surface of the Ice Barrier. Our sleds weighed 165 pounds each. Bjaaland, our ski and sledmaker, took the sleds in hand, and when spring arrived he had entirely made over our sledge equipment. These sleds weighed only one-third as much as the old ones. In the same way it was possible to reduce the weight of all other items of our equipment. Packing the provisions for the sledge journey was of the greatest importance. Captain Johansen attended to this work during the winter. Each of the 42,000 loaves of hard bread had to be handled separately before it could be assigned to its proper place. In this way the winter passed quickly and agreeably. All of us were occupied all the time. Our house was warm, dry, light and airy, and we all enjoyed the best of health. We had no physician and needed none.
Meteorological observations were taken continuously. The results were
surprising. We had thought that we should have disagreeable, stormy
weather, but this was not the case. During the whole year of our
sojourn at the station we experienced only two moderate storms. The
rest of the time light breezes prevailed, mainly from an easterly
direction. Atmospheric pressure was as a rule very low, but remained
constant. The temperature sank considerably, and I deem it probable
that the mean annual temperature which we recorded, -26° Centigrade, is
the lowest mean temperature which has ever been observed. During five
months of the year we recorded temperatures below -50° Centigrade. On
August 23d the lowest temperature was recorded, -59°. The
On August 24th the sun reappeared. The winter had ended. Several days earlier we had put everything in the best of order, and when the sun rose over the Barrier we were ready to start. The dogs were in fine condition.
