Madigan's and Stillwell's parties broke trail to the east on the morning of the 17th while we were still attending to the sledges and dogs preparatory to departure. It was decided that Gadget, a rather miserable animal, who had shown herself useless as a puller thus far, should be killed. The following dogs then remained:--Basilisk, Shackleton, Ginger Bitch, Franklin, John Bull, Mary, Haldane, Pavlova, Fusilier, Jappy, Ginger, George, Johnson, Castor, Betli and Blizzard. We went in pursuit of the other six men over a surface of rough sastrugi. The dogs, who were in fine fettle, rushed the sledges along, making frantic efforts to catch up to the parties ahead, who showed as black specks across the white undulating plain. At noon all lunched together, after which we separated, shaking hands warmly all round and interchanging the sledgers' "Good luck!" Our dogs drew away rapidly to the east, travelling on a slight down grade; the other two parties with their man-hauled sledges following in the same direction. The surface was splendid, the weather conditions were ideal, the pace, if anything, too rapid, for capsizes were apt to occur in racing over high sastrugi. Any doubts as to the capability of the dogs to pull the loads were dispelled; in fact, on this and on many subsequent occasions, two of us were able to sit, each one on a sledge, while the third broke trail ahead. In sledging over wide, monotonous wastes with dogs as the motive power, it is necessary to have a forerunner, that is, somebody to go ahead and point the way, otherwise the dogs will run aimlessly about. Returning over old tracks, they will pull along steadily and keep a course. In Adelie Land we had no opportunity of verifying this, as the continuous winds soon obliterated the impression of the runners. If the weather is reasonably good and food is ample, sledging dogs enjoy their work. Their desire to pull is doubtless inborn, implanted in a long line of ancestors who have faithfully served the Esquimaux. We found that the dogs were glad to get their harnesses on and to be led away to the sledge. Really, it was often a case of the dog leading the man, for, as soon as its harness was in place, the impatient animal strained to drag whatever might be attached to the other end of the rope. Before attaching a team of dogs to a sledge, it was necessary to anchor the latter firmly, otherwise in their ardour they would make off with it before everything was ready.
