September 29.—Whilst the man was out looking for the horses, which had strayed a little during the night, I took a set of angles to several heights, visible from the camp; upon the man’s return, he reported that he had found some fresh water, but upon riding to the place, I. found it was only a very small hole in a sheet of limestone rock, near the salt watercourse, which did not contain above a pint or two. The natives, however, appeared to come to this occasionally for their supply; similar holes enabling them frequently to remain out in the low countries long after the rain has fallen. After seeing the party move on, with the native boy to act as guide through the scrub, I rode in advance to search for water at the hill marked by Flinders as Bluff Mount, and named by Colonel Gawler, Mount Hill. This isolated elevation rises abruptly from the field of scrub, in the midst of which it is situated and is of granite formation; nearly at its summit is an open grassy plain, which was visible long before we reached it, and which leads directly over the lowest or centre part of the range; water was found in the holes of rock in the granite, and the grass around was very tolerable. Having ascertained these particulars, I hurried back to the drays to conduct them to a place of encampment. The road was very long and over a heavy sandy country, for the most part densely covered with scrub, and it was late, therefore, when we reached the hill. The horses, however, had good feed and fair allowance of water, but of the latter they drank every drop we could find. During our route to–day, I noticed some little distance to the north–west of our track, a high scrubby range, having clear grassy–looking openings at intervals. In this direction, it is probable that a better line of road might be found than the one we had chosen.
