it is thoroughly warm, the air breathlessly still, and the ponies resting in great comfort. If the snow has finished, the surface deposit, which is three to four inches thick, ought to diminish rapidly. Yet it is painful struggling on through this snow, though the ponies carry it gallantly enough. Christopher has now been harnessed three times without difficulty. After One Ton Camp it ought to be possible to stop him for a midnight halt and so get through the easier on long marches. Nearly 12 statute miles without a stop must be a big strain on the rearguard animals. One Ton Camp is only about 7 miles farther. Meanwhile we passed two of Evans' cairns to-day and one old cairn of last year, so that we ought to have little difficulty in finding our depôt.
Although we have been passing the black land of the Bluff I have not seen a sign of this land for four days. I had not thought it possible that misty conditions could continue for so long a time in this region; always before we have seen the land repeatedly. Either the whole sky has been clear, or the overhanging cloud has lifted from time to time to show the lower rocks. Had we been dependent on land marks we should have fared ill. Evidently a good system of cairns is the best possible travelling arrangement on this great snow plain. Meares and Demetri up with the dogs as usual very soon after we camped.
This inpouring of warm moist air, which gives rise to this heavy surface deposit at this season, is certainly an interesting meteorological fact, accounting as it does for the very sudden change in Barrier conditions from spring to summer.
