These preparations went on apace, and with a view to starting on the Southern march from the nearest possible point to the Pole, stores, etc., were transferred to Hut Point, and depots were also laid to help the travellers on their way. Adams, Marshall, and Wild were chosen to accompany Shackleton in this determined effort to reach the South Pole, and on 29th October they set out with the four ponies and the four sledges. By 3rd November they had left the sea-ice and were on the Barrier; but instead of finding a better surface they found it increasingly difficult. At the outset, however, the ponies did splendid work, though one of them, on 9th November, nearly disappeared into "a great fathomless chasm." At the time the travellers were in a nest of crevasses, and Adams's pony suddenly went down a crack. Fortunately, with help from Wild and Shackleton, the pony and the sledge were saved from falling into this abyss; but it was an alarming incident, for, as all the cooking gear and biscuits and a large portion of the oil were on this sledge, the loss of it would have been an irretrievable disaster to the Southern journey. The 26th November was a day to be remembered by Shackleton and his companions, for at night they found that they had reached latitude 82° 18' S., and so had passed Scott's "farthest south." On 1st December, latitude 83° 16' S. was reached, but by this time three of the ponies had been killed, and only one was left. A few days later this last pony disappeared down a crevasse, and nearly took Wild and the sledge with him. Serious as the loss of this gallant pony was, there was great cause for thankfulness that Wild and the sledge had almost miraculously been saved. Had the sledge gone, only two sleeping bags would have been left for the four men, and the equipment would have been so short that the explorers could scarcely have got back to winter quarters. Presently the travellers left the Barrier and attacked the great Beardmore Glacier which was between them and the plateau. On 9th December, 340 geographical miles lay between them and the Pole, and progress was painfully slow, for the surface consisted mainly of rotten ice through which their feet continually broke. A week later they had travelled over nearly 100 miles of crevassed ice, and had risen 6,000 feet; but the plateau which they so eagerly longed to reach still lay ahead of them. "Never," Shackleton wrote, "do I expect to meet anything more tantalizing than the plateau." Appalling surfaces, to walk on which Wild described as like walking over the glass roof of a station, continued after the plateau had been reached, and before Christmas arrived it was obvious, if the advance was to be continued, that absolute hunger, amounting almost to starvation, stared the explorers in the face.
