The country was perfectly flat on both sides of the river, and showed traces of tremendous floods.  The soil near the river was often deeply-cracked mud, water very scarce, and grass seldom seen.  The back country was covered with scrubs of dead acacia, the soil a red sand or gravel; and such was the unpromising appearance that I began to fear that our horses would soon fail for want of food and water; but having camped at a waterhole during Sunday to rest the party, heavy rain commenced, and though the greater portion of the water was absorbed by the dry soil, some of the channels of the river filled and commenced to flow.  This relieved us from much difficulty as regarded the want of water, and enabled us to seek for grass in positions which were otherwise inaccessible.

3rd May.

Just as we were leaving our camp a party of seven natives made their appearance; but though they came up to us, and talked much, I could get no useful information from them.  As the party moved on they followed us, and thinking they were not observed, made an attempt to throw a spear at one of the men; but Mr. C. Gregory, wheeling his horse quickly and presenting a revolver at the intending aggressors, they ran away, and left us to pursue our journey in peace.

The Thompson river.

4th May to 6th May.

The abundance of water was not without its inconveniences, and had the rain continued the party would have been annihilated, as our camp was between the deep channels which intersected the plain; and in attempting to extricate ourselves from the plains subject to inundation, found ourselves so completely entangled among the numerous deep channels and boggy gullies, in some of which the horses narrowly escaped suffocation in the soft mud, that after having forded one branch of the river, carrying the whole equipment across on our own backs, constructing a bridge over a second for the transport of the stores, and dragging the horses through as we best could with ropes, after three days of severe toil we had scarcely accomplished a direct distance of five miles.  The dry weather which followed rapidly hardened the surface of the clay plains, and I attempted to steer due west to the Thompson, but found the country so destitute of feed, and covered with dense acacia scrub, that we were compelled to return to the plains on the bank of the river.

8th May.

The valley of the river trending west was somewhat contracted, and did not exceed five or six miles in breadth; the plains were firmer, salt-bush and grass more abundant, and the horses recovered slightly from the effects of the barren country.  Keeping back from the right bank of the main channel, we passed some ridges of drift sand, and came on a fine lagoon nearly a mile in length.  Here we surprised a party of natives, who decamped on our approach, leaving a net, fish, etc., which we of course left untouched, and camped at a spot lower down the lagoon.
