when it could be observed, was always towards the west and north-west,
obliging me to believe that either the country continued a desert of
sand as at present, or that its westerly inclination would cause all
that part of it to consist of marshes and swamps. Since quitting the
river we have not enjoyed what under any other circumstances would be
called drinkable water; what was found being merely the contents of
shallow mud holes, in the bottom of acacia swamps, over which the
dryness of the season alone enabled us to travel. We have uniformly been
obliged to strain our water before we drank it, and its taste, from the
decayed vegetable matter it contained, was sour and unpleasant.

June 5.--A clear cold frosty morning: sent the horses to the watering
place: if it be any way possible to get them on, it is my intention to
proceed to-morrow morning, as it is almost as much labour to them to go
for water as it would be to perform a short day's journey.

From every thing I can see of the country to the south-west, it appears,
upon the most mature deliberation, highly imprudent to persevere longer
in that direction, as the consequences to the horses of want of water
and grass might be most serious; and we are well assured that within
forty miles on that point the country is the same as before passed over.
In adopting a north-westerly course, it is my intention to be entirely
guided by the possibility of procuring subsistence for the horses, that
being the main point on which all our ulterior proceedings must hinge.
It is however to be expected that as the country is certainly lower to
the west and north-west than from south-east to south-west, there is a
greater probability of finding water in this latter direction. In our
present perplexing situation, however, it is impossible to lay down any
fixed plan, as (be it what it may) circumstances after all must guide us.
Our horses are unable to go more than eight or ten miles a day, but even
