On the 6th, we journeyed again through a barren scrub, although on firmer ground, and passed numerous groups of huts. At about eight miles from our last encampment, we came upon the river, where its banks were of considerable height. In riding along them, Mr. Hume thought he observed a current running, and be called to inform me of the circumstance. On a closer examination, we discovered some springs in the very bed of the river, from which a considerable stream was gushing, and from the incrustation around them, we had no difficulty in guessing at their nature: in fact, they were brine springs, and I collected a quantity of salt from the brink of them. DISTRESS FOR WANT OF FRESH WATER. After such a discovery, we could not hope to keep our position. No doubt the current we had observed on first reaching the river, was caused by springs that had either escaped our notice or were under water. Here was at length a local cause for its saltness that destroyed at once the anticipation and hope of our being near its termination, and, consequently, the ardour with which we should have pressed on to decide so interesting a point. Our retreat would have been a measure of absolute necessity ere this, had we not found occasional supplies of fresh water, the last pond of which was now about eighteen miles behind us. OUR COURSE ARRESTED. Whether we should again find any, was a doubtful question, and I hesitated to run the risk. The animals were already, from bad food, and from the effects of the river water, so weak, that they could scarcely carry their loads, and I was aware, if any of the bullocks once fell, he would never rise again. Under such circumstances, I thought it better to halt the party at the edge of the scrub, though the feed was poor, and the water not drinkable. Our situation required most serious consideration. It was necessary that we should move either backward or forward in the morning. Yet we could not adopt either measure with satisfaction to ourselves, under such unfavorable circumstances. I determined to relieve my own mind by getting the animals into a place of safety, as soon as possible; and, as the only effectual way of doing this was to retire upon the nearest fresh water, I resolved at once to do so. The party turned back on the morning of the 6th; nor do I think the cattle would ever have reached their destination had we not found a few buckets of rain water in the cleft of a rock, to refresh them. Thus it will appear that under our most trying circumstances, we received aid from Providence, and that the bounty of Heaven was extended towards us, when we had least reason to expect it.
