If we fail, there must be a retreat westwards at least seventy miles.

Barometer 28.53; thermometer 64 degrees at 5 p.m.
WATER FOUND.
7th.
Early this morning Pierre and I and my brother and Windich started off in search of water, as there was scarcely any left at camp.

Unless we are fortunate enough to find some, retreat is inevitable.

Pierre and myself searched the range we were camped in, while Windich and my brother went further south towards another range.

We searched all round and over the rough ranges without success, and reached camp at one o'clock.
