arance of anything like a crater. In the lower or front hills the
rock was argillaceous, of a hard slaty nature, and inclined at an angle
of about 45 degrees from the horizontal. This formation was frequently
traversed by dykes of grey limestone of a very hard texture.

Upon watering the horses at the hole in the rock, I was much disappointed
to find that they had already sunk it eighteen inches, and now began to
fear that it would not last them so long as I had anticipated, and that I
should still be obliged to cross over the hills to the very rocky channel
where I had found permanent water on the 15th of July. This I was
desirous, if possible, to avoid, both from the difficult nature of the
road by which that water must be reached, and from the circumstance that
it was going so much out of our way into an all but impracticable
country, and that consequently, when we did move on again to the north,
we should be obliged to come all the way back again over the same bad
road to gain the open country under Flinders range, where alone we could
hope to make any progress with the drays.

July 31.--Having remained all day in camp to rest the party, I found that
the horses had again made a great diminution in the depth of the water in
the rock, I therefore had the drays all prepared in the evening,
intending to move away to the other water-course in the morning; but the
next day the horses had unfortunately strayed, and it was late before
they were brought up, so that we could not get away. Upon watering them
when they arrived, I found that less impression was made upon the water
than on the previous days; and after an anxious consultation with my
overseer, I decided upon leaving the party in camp at Depot Pool until I
could reconnoitre further north and return.

August 1.--To prevent any difficulties during my absence, in the event of
the water failing in the rocky hole, I sent the native boy to shew the
overseer the place where the permanent water was, and gave him
instructions to move the party thither if he should find it necessary;
but not until their safety absolutely required it, or before he had fully
ascertained that no water was to be procured by digging in the bed of any
of the adjoining watercourses. During his absence, I employed myself
busily in getting ready for another push to the north with the native boy
to search for a new depot, as in a country so difficult and embarrassing,
it was quite impracticable to mo
