120 will remember that it was at the Bluff Camp that Teddy Evans returned with the three weak ponies, so there were plenty of traces of our march now. Just on four miles from the start I saw a small mound some distance to the west, and struck over there: it was a small cairn without the signs of a camp and rather puzzled me at the time. As I shall mention it later I will call it X for convenience. We then pushed on and I found steering most difficult. In the fuzzy nothingness ahead one could see no point on which to fix the eye, and the compass required standing still to look at it every time. Our sledging compasses are spirit ones, and as steady as a small hand compass could possibly be. You will understand, however, that owing to the proximity of the Magnetic Pole the pull on the needle is chiefly downwards. It is forced into a horizontal position by a balancing weight on the N. side, so it is obvious that its direction power is greatly reduced. On the ship, owing to the vibration of the engines and the motors, we were absolutely unable to steer by the compass at all when off the region of the Magnetic Pole.

On this occasion (February 21) we zig-zagged all over the place—first I went ahead, and Oates said I zig-zagged, then he went ahead, and I understood at once, as it was impossible to walk straight for two consecutive minutes. However, we plodded along with frequent stoppages till the wind came away, and then having determined the direction of that, steered by keeping the snow on our backs. The wind was not strong enough to be unpleasant, and all was well. We legged it into the void for nearly seven miles beyond X Cairn when I suddenly found myself only a few yards away from another cairn. This shows that somehow, without the use of tracks or landmarks, we had marched seven miles without being able to see thirty yards, and had yet hit off the direct track to a T; of course, it was only coincidence, though some people might credit themselves with superlative navigating powers on such evidence. The wind increased, and with the knowledge I now have of blizzards I would camp at once. Then I thought it better to shove on, as the ponies were marching splendidly. The
