be alive, and, having lived through the winter, the arrival of help might make the difference between life and death.
On the other hand we knew that the Polar Party must be dead. They might be anywhere between Hut Point and the Pole, drifted over by snow, or lying at the bottom of a crevasse, which seemed the most likely thing to have happened. From the Upper Glacier Depôt in 85° 5′ S. to the Pole, that is the whole distance of the Plateau Journey, we did not know the courses they had steered nor the position of their depôts, for Lieutenant Evans, who brought back the Last Return Party, was invalided home and neither of the seamen who remained of this party knew the courses.
After the experience of both the supporting parties on their way down the Beardmore Glacier, when we all got into frightfully crevassed areas, it was the general opinion that the Polar Party must have fallen down a crevasse; the weight of five men, as compared with the four men and three men of the other return parties, supported this theory. Lashly was inclined to think they had had scurvy. The true solution never once occurred to us, for they had full rations for a very much longer period of time than, according to their averages to 87° 32′, they were likely to be out.
The first object of the expedition had been the Pole. If some record was not found, their success or failure would for ever remain uncertain. Was it due not only to the men and their relatives, but also to the expedition, to ascertain their fate if possible?
The chance of finding the remains of the Southern Party did not seem very great. At the same time Scott was strict about leaving notes at depôts, and it seemed likely that he would have left some record at the Upper Glacier Depôt before starting to descend the Beardmore Glacier: it would be interesting to know whether he did so. If we went south we must be prepared to reach this depôt: farther than that, I have explained, we could not track him. On the other hand, if we went south prepared to go to the Upper Glacier Depôt, the number of sledging men necessary, in view of the fact that we had no depôts,
