At the distance of about seventeen miles from the basin we were surprised by hearing the noise of a fall of water; but distrusting our ears we were not convinced of the fact, until an opening in the mangroves exposed to our view a cascade of water of one hundred and sixty feet in breadth, falling from a considerable height. As the breeze still enabled us to make way against the tide we did not stay to examine it; and therefore deferred our visit until our return. Three miles farther up we put ashore to rest and refresh the boat's crew; and whilst I was occupied at the beach Mr. Hunter ascended the hill to examine the country but found only a continuation of the same rocky hills and sterile desert. The character of the river had assumed nearly the same appearance as Hunter and Roe's Rivers in Prince Frederic's Harbour, excepting that the hills were less precipitous and rather more wooded. About two miles beyond our station the width began to decrease and the stream to take a more winding course: the banks were also lower and the mangroves appeared to increase in quantity; but unlike the other rivers the bottom was of sand and there was scarcely any mud, excepting on the banks where the mangroves grew. Several places were observed upon the hills where the trees and grass had been burnt by fire, but otherwise there was no sign of the banks of the river ever being frequented by natives. By the time we had refreshed ourselves it was getting late and we set out on our return; the tide had now ebbed considerably and exposed several banks which, having been covered, had before escaped our observation; we grounded on several as we proceeded, which detained us so long that it was dark when we passed the cascade, and by the time we reached the island on which we had seen the alligator in the morning, the tide had commenced to flow. Here we determined upon remaining until the ebb; and after satisfying ourselves that there were no alligators upon it landed, and kindled a fire upon the dry summit of the island under a large log of wood that had been washed down the river and deposited there by the freshes. Whilst our refreshment was preparing we searched about for alligators, but not finding any and being quite overpowered by the fatigues of the day, we composed ourselves to rest; during which, although the alligators did not trouble us, we were greatly incommoded by sandflies and mosquitoes; but neither our fear of the former, nor the annoyance of the latter, prevented our sleeping as soundly as we should have done on a more safe and luxurious couch. Mr. Hunter also, who for some time after the rest had fallen asleep walked about in order to keep on the alert, very soon followed our example and we happily passed the night without accident.
