We are continually falling, for we are unable to distinguish the high and low parts of the sastrugi surface.

We are travelling on our ski.

We camped at 6 p.m.after travelling 6 miles 100 yds.

I am writing this sitting up in the bag.

This is the first occasion I have been able to do thus for some time, for usually the cold has penetrated through everything should one have the bag open.
The temperature is a little higher to-night, but still it is -21ｰ Fahr.
(53ｰ of frost).
