Its banks were too precipitous to allow of our watering the cattle, but the men eagerly descended to quench their thirst, which a powerful sun had contributed to increase; nor shall I ever forget the cry of amazement that followed their doing so, or the looks of terror and disappointment with which they called out to inform me that the water was so salt as to be unfit to drink! This was, indeed, too true: on tasting it, I found it extremely nauseous, and strongly impregnated with salt, being apparently a mixture of sea and fresh water. Whence this arose, whether from local causes, or from a communication with some inland sea, I knew not, but the discovery was certainly a blow for which I was not prepared. Our hopes were annihilated at the moment of their apparent realization. The cup of joy was dashed out of our hands before we had time to raise it to our lips. Notwithstanding this disappointment, we proceeded down the river, and halted at about five miles, being influenced by the goodness of the feed to provide for the cattle as well as circumstances would permit. They would not drink of the river water, but stood covered in it for many hours, having their noses alone exposed above the stream. Their condition gave me great uneasiness. It was evident they could not long hold out under their excessive thirst, and unless we should procure some fresh water, it would impossible for us to continue our journey. On a closer examination, the river appeared to me much below its ordinary level, and its current was scarcely perceptible. We placed sticks to ascertain if there was a rise or fall of tide, but could arrive at no satisfactory conclusion, although there was undoubtedly a current in it. Yet, as I stood upon its banks at sunset, when not a breath of air existed to break the stillness of the waters below me, and saw their surface kept in constant agitation by the leaping of fish, I doubted whether the river could supply itself so abundantly, and the rather imagined, that it owed such abundance, which the pelicans seemed to indicate was constant, to some mediterranean sea or other. Where, however, were the human inhabitants of this distant and singular region? The signs of a numerous population were around us, but we had not seen even a solitary wanderer. The water of the river was not, by any means, so salt as that of the ocean, but its taste was precisely similar. Could it be that its unnatural state had driven its inhabitants from its banks?
