We then bent our steps to the water-gully, but, to our mortification, it was quite dried up, and exhibited no vestige of its having contained any for some time. From the more luxuriant and verdant appearance of the trees and grass than the country hereabout assumed last year, when the water was abundant, we had felt assured of finding it and therefore our disappointment was the greater. July 24. After another unsuccessful search in the bight, to the eastward of Careening Bay, in which we fruitlessly examined a gully that Mr. Cunningham informed me had last year produced a considerable stream, we gave up all hopes of success here, and directed our attention to the cascade of Prince Regent's River; which we entered the next afternoon, with the wind and tide in our favour, and at sunset reached an anchorage at the bottom of St. George's Basin, a mile and a half to the northward of the islet that lies off the inner entrance of the river, in seven fathoms muddy sand. July 26. The following morning at half-past four o'clock Mr. Montgomery accompanied me in the whale-boat to visit the cascade; we reached it at nine o'clock and found the water, to our inexpressible satisfaction, falling abundantly. While the boat's crew rested and filled their baricas, I ascended the rocks over which the water was falling and was surprised to find its height had been so underrated when we passed by it last year: it was then thought to be about forty feet, but I now found it could not be less than one hundred and fifty. The rock, a fine-grained siliceous sandstone, is disposed in horizontal strata, from six to twelve feet thick, each of which projects about three feet from that above it, and forms a continuity of steps to the summit, which we found some difficulty in climbing; but where the distance between the ledges was great we assisted our ascent by tufts of grass firmly rooted in the luxuriant moss that grew abundantly about the water-courses. On reaching the summit, I found that the fall was supplied from a stream winding through rugged chasms and thickly-matted clusters of plants and trees, among which the pandanus bore a conspicuous appearance and gave a picturesque richness to the place. While admiring the wildness of the scene, Mr. Montgomery joined me; we did not however succeed in following the stream for more than a hundred yards, for at that distance its windings were so confused among rocks and spinifex that we could not trace its source. After collecting for Mr. Cunningham, who was confined on board by sickness, a few specimens of those plants which, to me, appeared the most novel, we commenced our descent, and reached the bottom in safety; by which time the tide was ebbing so rapidly that we set off immediately on our return with a view of arriving on board by low-water, in order that no time might be lost in sending the boats up with our empty water-casks.
