The plains, as we passed, were covered with the most luxuriant grass and herbage.  Plants of the leguminosae and compositae, were by far the most prevalent; the colour of the former, generally a showy red, that of the latter, a bright yellow.  Belts of open forest land, principally composed of the Box-tree of the Colonists (a species of Eucalyptus), separate the different plains; and patches of scrub, consisting of several species of Acacias, and of a variety of small trees, appear to be the outposts of the extensive scrubs of the interior.  There are particularly three species of Acacias, which bestow a peculiar character on these scrubs:  the one is the Myal (A. pendula)—­first seen by Oxley on Liverpool Plains, and afterwards at the Barwan, and which exists in all the western plains between the Barwan and Darling Downs—­whose drooping foliage and rich yellow blossoms render it extremely elegant and ornamental.  The second, the Acacia of Coxen, resembles the Myal (without its drooping character), its narrow lanceolate phyllodia rather stiff, its yellowish branches erect.  The third, is the Bricklow Acacia, which seems to be identical with the Rose-wood Acacia of Moreton Bay; the latter, however, is a fine tree, 50 to 60 feet high, whereas the former is either a small tree or a shrub.  I could not satisfactorily ascertain the origin of the word Bricklow [Brigaloe, Gould.], but, as it is well understood and generally adopted by all the squatters between the Severn River and the Boyne, I shall make use of the name.  Its long, slightly falcate leaves, being of a silvery green colour, give a peculiar character to the forest, where the tree abounds.

Oct. 1.—­After having repaired some harness, which had been broken by our refractory bullocks upsetting their loads, and after my companions had completed their arrangements, in which Mr. Bell kindly assisted, we left Jimba, and launched, buoyant with hope, into the wilderness of Australia.

Many a man’s heart would have thrilled like our own, had he seen us winding our way round the first rise beyond the station, with a full chorus of “God Save the Queen,” which has inspired many a British soldier,—­aye, and many a Prussian too—­with courage in the time of danger.  Scarcely a mile from Jimba we crossed Jimba Creek, and travelled over Waterloo Plains, in a N. W. direction, about eight miles, where we made our first camp at a chain of ponds.  Isolated cones and ridges were seen to the N. E., and Craig Range to the eastward:  the plains were without trees, richly grassed, of a black soil with frequent concretions of a marly and calcareous nature.  Charley gave a proof of his wonderful power of sight, by finding every strap of a pack-saddle, that had been broken, in the high grass of Waterloo Plains.

Oct. 2.—­Bullocks astray, but found at last by Charley; and a start attempted at 1 o’clock; the greater part of the bullocks with sore backs:  the native tobacco in blossom.  One of the bullocks broke his pack-saddle, and compelled us to halt.
