miles from the former place are three large holes with water from two to three feet deep in the deepest part, and at six miles further another large one which might almost be termed a lake, being nearly 1000 links square.  About these there were some lines of sandhills running about north-east and south-west; and in one of the flats between the sandhills I found several pieces of satin spar in lumps of the size of one’s hand, partially buried in the ground, and all of them with the plane of cleavage nearly perpendicular with the surface to the ground.

Balloo, or Wright’s Creek.—­The lower portion of Wright’s Creek, called by the natives “Balloo,” is situated in latitude 28 degrees 48 minutes south, and longitude 142 degrees 53 minutes east by account.  At this point, the creek, after breaking into several small channels, runs out on a grassy plain, the water running in a southerly direction, probably until it meets that from the Torrens and other creeks at the Cangapundy Swamp.  There was plenty of water in this part of the creek when we passed, but I cannot speak to its permanence.  The banks are well lined with box timber, as well as with marshmallows and wild spinach:  the land on either side consists of well-grassed sandy rises.  At four or five miles above this, the creek is a narrow, dry, sandy watercourse, winding through a grassy valley, which everywhere presents indications of the most violent floods.  Beyond this is an extensive grassy plain; and for three or four miles scarcely a trace of the creek could be seen.  We then came to a clump of trees, amongst which were two large waterholes surrounded by polygonum bushes, and containing great numbers of small fish.  These holes appear to be permanent.  We found about sixty blacks camped here.  Above these waterholes, which are together about half a mile long, the creek again disappears on the plain.  The land for the next ten or twelve miles in a north-north-easterly direction is very fine for pastoral purposes, being alternately grassy plains and ridges.  At twelve or thirteen miles we crossed the creek where it has cut for itself a deep narrow channel, the banks of which are densely timbered and well grassed, but the waterholes are small, and contained very little water.  For a distance of six miles the creek is of a very insignificant character.  It appears to be divided into several branches, which traverse clay flats badly grassed.  Here and there are some lines of low sandy rises, with plenty of feed on them.  All the watercourses are distinctly marked by lines of box timber.  At about nine miles from where we crossed the creek, and after traversing some loose polygonum ground, which was covered with mussel shells and a shell resembling a periwinkle, we came to a branch of the creek containing a splendid waterhole 150 links broad and about half a mile long.  A little above this the creek again disappears for a short distance, and then there is a long narrow channel of undoubtedly permanent water,
