not counting the bends.  For the whole of this distance we found not a break or interruption of water, which appears to be very deep; the banks are from twenty to thirty feet above the water, and very steep; they are clothed near the water’s edge with mint and other weeds, and on the top of each side there is a belt of box trees and various shrubs.  The lower part of the creek is bounded towards the north by a high red sand ridge, and on the south side is an extensive plain, intersected by numerous watercourses, which drain off the water in flood-time.  The greater portion of the plain is at present very bare, but the stalks of dry grass show that after rain or floods there will be a good crop on the harder and well drained portion; but I believe the loose earthy portion supports no vegetation at any time.  The inclination of the ground from the edge of the creek-bank towards the plain is in many places very considerable; this I should take to indicate that the flooding is or has been at one time both frequent and regular.

Wednesday, 26th December, 1860.—­We started at five A.M., following up the creek from point to point of the bends.  Its general course was at first north-by-west, but at about six miles, the sand ridge on the west closed in on it, and at this point it takes a turn to the north-north-east for half a mile, and then comes around suddenly north-west.  Up to this point it had been rather improving in appearance than otherwise, but in the bend to the north-west the channel is very broad.  Its bed being limestone rock and indurated clay, is for a space of five or six chains quite dry; then commences another waterhole, the creek keeping a little more towards north.  We crossed the creek here and struck across the plain in a due north course, for we could see the line of timber coming up to the sand ridges in that direction.  For from seven to eight miles we did not touch the creek, and the eastern sand ridge seceded to a distance, in some places of nearly three miles, from our line, leaving an immense extent of grassy plain between it and the creek.  The distinctly marked feature on the lower part of this creek is that whenever the main creek is on one side of a plain, there is always a fine billibong on the opposite side, each of them almost invariably sticking close to the respective sand ridges.  Before coming to the next bend of the creek a view from the top of a sandhill showed me that the creek received a large tributary from the north-west at about two miles above where we had crossed it.  A fine line of timber, running up to the north-west, joined an extensive tract of box forest, and the branch we were following was lost to view in a similar forest towards the north.  The sand ridge was so abrupt when we came to the creek, that it was necessary to descend into its bed through one of the small ravines adjoining it.  We found it partially run out, the bed being sand and strewed with nodules of lime, some of which were from one half to two feet long:  they had apparently been formed in the sanddowns by infiltration.
