The river evidently overflowed its banks, on both sides, for many miles, nor had I a doubt that, at some periods, the space northward, between it and the Lachlan, presented the appearance of one vast sea. The flats of polygonum stretched away to the N.W. to an amazing distance, as well as in a southerly direction, and the very nature of the soil bore testimony to its flooded origin.
In viviparous flowers, as those of allium magicum, and polygonum viviparum, the anthers and the stigmas become effete and perish; and the lateral or paternal offspring succeeds instead of seeds, which adhere till they are sufficiently mature, and then fall upon the ground, and take root like other bulbs.
At about 20 miles we made an angle of the river where the left bank was 50 feet high. None of the usual indications of the neighbourhood of the Darling appeared here. No flats of Polygonum junceum, nor falls in the ground. The river was evidently encroaching on this high bank which consisted of red sandy earth to the depth of ten feet. Below this stratum was clay mixed with calcareous concretions.
The only trees now to be seen were a few box-trees along their skirts, and on the line of the creeks, which last were a perfectly new feature in the country, and surprised me greatly. The tract we passed over on this day was certainly more subject to overflow than usual. Large flats of polygonum, and plains having rents and fissures in them, succeeded those I have already described.
Changed to south-west. At two miles and a half struck our tracks and proceeded to Lawson Creek. We found the open parts of the plain black alluvial soil so rotten and cracked, that the horses were sinking over their knees; this continued for six miles. It is covered with long grass and polygonum; also a few eucalypti scattered over it.
The seven men who had introduced us, went back at the same time that we continued our journey, and two more belonging to the new tribe, went on a-head to prepare the the neighbouring tribe to receive us; nor did we see anything more of them during the day. We encamped on the left bank of the river, amidst a polygonum scrub, in which we found a number of the crested pigeon.
It is about four inches long and half an inch in thickness, and is obtained by attaching a thin narrow hook of hard wood to the long, wiry shoots of the polygonum, and then pushing this gently down the hole through which the grub has burrowed into the earth until it is hooked. Grubs are procured at a depth of seven feet in this way without the delay or trouble of digging.
The soil upon this plain differed in character from that on the plains to the eastward, and was much freer from sand. Continuing our journey, at 2 p.m. we cleared the plain, and entered a tract covered with the polygonum junceum, on a soil evidently the deposit of floods. Box-trees were thinly scattered over it, and among the polygonum, the crested pigeons were numerous.
The crested pigeon made its appearance on the acacias, which I took to be a sure sign of our approach to a country more than ordinarily subject to overflow; since on the Macquarie and the Darling, those birds were found only to inhabit the regions of marshes, or spaces covered by the acacia pendula, or the polygonum.
In the channels within the scrub I found a large supply of water, in holes surrounded by sedges and a broad-leaved Polygonum, amongst which grew a species of Abutilon; the neighbouring dry channel was one beautiful carpet of verdure.
