On reaching 83° S., the explorers deposited provisions for five men and twelve dogs for four days, and depots were subsequently made at 84° S., and 85° S. It was from the latter depot that they decided to make what may, without exaggeration, be called their dash for the Pole. From their camp at 85° S., the distance to the Pole and back was 683 miles. After consideration Amundsen determined to take forward provisions, etc., for sixty days on the sledges, and depot the rest of the supplies and outfit. A weary ascent to the plateau lay before the explorers, and they started upon it on 17th November. Three days later they had reached the plateau, but although they were happy enough in having accomplished a long and dangerous climb, their first camp on the plateau was not one of happy memory. Grim work had to be done. Amundsen arrived on the plateau with forty-two dogs, but twenty-four of them had to be killed when the plateau was reached. It was a sacrifice that had to be made if the success of the expedition was to be considered; but no one can read Amundsen's account of it without recognizing how bitterly he and his companions regretted the necessity. This camp, not without reason, was called "The Butcher's Shop," and as both the men and dogs required rest before setting out on the final stages of their march, it had been decided to remain there for two days. The eighteen remaining dogs were divided into three teams, with six dogs in each team, and one sledge was left behind. But owing to the weather the explorers could not leave this hated "Butcher's Shop" until 25th November, and when they did set out again a blizzard was blowing. So tired, however, were they of waiting in such an inhospitable and gruesome spot, that all of them were eager to quit it--whatever the conditions of the weather might be. Fog subsequently impeded the party, and again and again Amundsen blessed the assistance that they received from ski. "I am not," he wrote, "giving too much credit to our excellent ski when I say that they not only played a very important part, but possibly the most important of all, on our journey to the South Pole. Many a time we traversed stretches of surface so cleft and disturbed that it would have been an impossibility to get over them on foot."* * _The South Pole_, Vol. II., page 89. The 7th December was a great day for the expedition, because during it they passed Shackleton's "farthest south," 88° 23' S. They proceeded for another two miles, and then determined to make their last depot. So important to them was this depot that they not only marked it at right angles to their course, but also by snow beacons at every two miles to the south.
