This seemed to us a charming spot, so opportunely and unexpectedly found, and we alighted on a fine grassy flat by the margin of a small lagoon, where stood a most graceful group of bushes for shelter or shade. After sunset, the sky was overcast with very heavy clouds; the air was sultry, and we expected rain. 15TH SEPTEMBER.--As soon as daylight appeared I hastened towards the gap, and ascended a naked rock on the west side of it. I there beheld downs and plains extending westward beyond the reach of vision, bounded on the S. W. by woods and low ranges, and on the N. E. by higher ranges; the whole of these open downs declining to the N. W., in which direction a line of trees marked the course of a river traceable to the remotest verge of the horizon. There I found then, at last, the realization of my long cherished hopes, an interior river falling to the N. W. in the heart of an open country extending also in that direction. Ulloa's delight at the first view of the Pacific could not have surpassed mine on this occasion, nor could the fervour with which he was impressed at the moment have exceeded my sense of gratitude, for being allowed to make such a discovery. From that rock, the scene was so extensive as to leave no room for doubt as to the course of the river, which, thus and there revealed to me alone, seemed like a reward direct from Heaven for perseverance, and as a compensation for the many sacrifices I had made, in order to solve the question as to the interior rivers of Tropical Australia. To an European, the prospect of an open country has a double charm in regions for the most part covered with primaeval forests, calling up pleasing reminiscences of the past, brighter prospects for the future--inspiring a sense of freedom, especially when viewed from the back of a good horse:-- "A steed! a steed! of matchless speede, A sword of metal keene--All else to noble minds is drosse, All else on earth is meane!" --OLD SONG.
