The country to the northward continued to rise till it reached an elevation of something like 1,500 feet. Being also of a mountainous character, it was fondly hoped that here, at least, would be found the long-sought watershed. This anticipation was rather confirmed by the discovery of a beautiful stream, now called Salvator Rosa, which flowed northward with a clear and musical current. This pleasing delusion lasted only one day, for on the morrow the lovely river ended its course in a reedy lake, on the opposite side of which a channel was found, but it contained no water at that time. This is one of the heads of the Nogoa, a river trending too much to the east to suit Sir Thomas's purpose. Other discoveries of streams or watercourses were made soon afterwards, two of the principal being named the Claude and the Balmy Creek. These designations are suggestive of pleasant associations, and, while speaking well for the country, sufficiently prove that the expedition had its share of enjoyment as well as the usual experience of toil and fatigue. The 21st of July was rendered memorable by the discovery of the Belyando, a fine river, heading towards the north, and offering a better promise of leading to the Gulf. In this expectation, it was eagerly followed, and in four days conducted the explorers across the Tropic of Capricorn. In many parts the country was excellent, stretching out in splendid downs, which squatters have long since applied to a lucrative purpose, but in other places the axe had to be used to clear a path through the brigalow scrubs. In common with other explorers, Mitchell has noticed that "the Australian rivers have all distinguishing characteristics, which they seem to possess from their source to their termination." The Belyando was no exception. It was found throughout its course to have an unfortunate propensity for splitting into channels, which were often difficult to trace through the thick scrub; but, as a compensation, these branches afforded excellent facilities for storage of water against dry seasons. Many days of persevering travel gave the party a good northing, but, after passing over three and a half degrees of latitude, it began to be evident that the Belyando also was going to deceive them. It had been steadily, and latterly very decisively, making for the east, thus leaving no hope of conducting the expedition to Carpentaria. Mitchell rightly conjectured that it must be the tributary which Leichhardt had seen joining the Suttor, and, with a crushing feeling of disappointment, determined to change his front and return home.
