timbered. The more elevated plains are sandy, and support a fine
supply of healthy salt bushes, as well as here and there a few
grasses. On the rises to the south-south-east of Cannilta may be
seen great quantities of quartz rock, forming dykes in the schist
rises: the latter in some places adjoin, and run into hills of
loose stone, having the appearance of indurated clay. From
Cangapundy to Wright's Creek the ground is light-coloured, and of a
clayey nature: it forms a series of dry clay-pans, separated from
one another by low sandy banks, on which the vegetation was fresh
and green. At about seventeen 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
