enter and consume the dead wood, which formed the principal obstacle to our progress.  Difficult, however, as it was to penetrate such thickets with pack-bullocks, I had no choice left, and therefore proceeded in the same direction.  In a short time, we reached an open Bricklow scrub containing many dry water-holes, which, farther on, united into a watercourse.  We passed a creek flowing to the eastward to join the Mackenzie, and continued our route through patches of Bricklow scrub, alternating with Bastard-box forest, and open Vitex scrub, in which the Moreton Bay ash was very plentiful.  About eight miles from our camp, we came upon an open forest of narrow-leaved Ironbark (E. resinifera) and Bastard-box, covering gentle slopes, from which shallow well-grassed hollows descended to the westward.  Coming again on scrub, and following it down in a westerly direction, we came to a dry creek; and found water in holes along the scrub.  Considering this a favourable place for the camp, I sent Charley back, to guide my party through the scrub; whilst I proceeded with Brown to examine the creek upwards, to the north-west.  After a ride of about five miles, during which several fine lagoons were seen, we reached a prominent hill of sandstone formation, surrounded by a most beautiful, open, silver-leaved Ironbark forest, changing occasionally into plains without a tree.  I ascended the hill, and obtained a very extensive view from its summit.  A range of peaks bore N. 57 degrees W.; another range, with undulating outline, was seen to the south-east; and another less prominent range bore N. 45 degrees W. The hill is in latitude 23 degrees 10 minutes, and bears the name of Mount Stewart, in compliment to Mr. Stewart, veterinary surgeon of Sydney, to whom I am indebted for great assistance and most valuable advice.

Towards the north-east, the country appeared to be very level, with only one low ridge, apparently at a great distance.  To the south, and also to the west, some long-stretched flat-topped hills were visible, several extending as far as the eye could reach.  I continued my ride in the direction of the range of peaks to the north-west, over an undulating country of varied character, now extending in fine downs and plains, now covered with belts of thick Bricklow scrub, with occasional ridges of open silver-leaved Ironbark forest.  Among the latter was a rather stunted gum-tree, with a black scaly butt; it was very frequent, and greatly resembled the Moreton Bay ash.  The numerous watercourses which I crossed, were all dry; and, when the approach of night compelled us to select a camping place, which we did in a small grove of Bricklow, we should have been without water, had not a thunder-storm with light showers of rain, enabled us to collect about a quart of it to make some tea.  The next morning we continued our examination, passing over a country of scrub, plain, and forest land; and made our breakfast, and watered our horses, at a small
