NEARLY DRY. The uniformity of breadth and width in this streamlet and its tortuous course were curious, especially as it must lead the floods of the Lachlan almost directly back from the general direction of their current to supply a lake. Thus the fluviatile process seemed to be reversed here, the tendency of this river being not to carry surface waters off, but rather to spread over land where none could otherwise be found, those brought from a great distance. The particular position of this portion of depressed surface being so far distant from the general course of the river and the communication between it and the river by a backwater so shallow and small, the lake can only receive a small share of the river deposits and this only from the waters of its highest floods. We found the "noble lake" (as it appeared when discovered by Mr. Oxley) now for the most part a plain covered with luxuriant grass; some water, it is true, lodged on the most eastern extremity, but nowhere to a greater depth than a foot. Innumerable ducks took refuge there and also a great number of black swans and pelicans, the last standing high upon their legs above the remains of Regent's lake. We found the water perfectly sweet even in this shallow state. It abounds with the large freshwater mussel which was the chief food of the natives at the time we visited it. DEAD TREES IN IT. On its northern margin and a good way within the former boundary of the lake stood dead trees of a full-grown size which had been apparently killed by too much water, plainly showing, like the trees similarly situated in Lake George and Lake Bathurst, to what long periods the extremes of drought and moisture have extended, and may again extend, in this singular country. ROCKS NEAR IT. That the lake is sometimes a splendid sheet of water was obvious in its line of shores. These were overhung on the south-western side by rocky eminences which in some parts consisted of a red calcareous tuff containing fragments of schist; in others, of trap-rock or basalt which was very hard and black. The opposite shore was lower, with water-worn cliffs of reddish clay. By these cliffs and the beaches of drifted sand under them, we perceived that the prevailing winds in all times of high flood came from the south-west; the north-east side being very different from the opposite, which was free from sand and bore no such marks of chaffing waves.
