As they were treated with kindness, the natives who accompanied us soon threw off all reserve, and in the afternoon assembled at the pool below the fall to take fish. They went very systematically to work, with short spears in their hands that tapered gradually to a point, and sank at once under water without splash or noise at a given signal from an elderly man. In a short time, one or two rose with the fish they had transfixed; the others remained about a minute under water, and then made their appearance near the same rock into the crevices of which they had driven their prey. Seven fine bream were taken, the whole of which they insisted on giving to our men, although I am not aware that any of themselves had broken their fast that day. They soon, however, procured a quantity of muscles, with which they sat down very contentedly at a fire. My barometrical admeasurement gave the cataract an elevation of 680 feet above the level of the sea; and my observations placed it in east longitude 148 degrees 3 minutes and in latitude 31 degrees 50 minutes south. It became an object with us to gain the right bank of the Macquarie as soon as possible; for it was evident that the country to the southward of it was much more swampy than it was to the north: but for some distance below the cataract, we found it impossible to effect our purpose. The rocks composing the bed of the river at the cataract, which are of trapp formation, disappeared at about eight miles below it, when the river immediately assumed another character. Its banks became of equal height, which had not before been the case, and averaged from fifteen to eighteen feet. They were composed entirely of alluvial soil, and were higher than the highest flood-marks. Its waters appeared to be turbid and deep, and its bed was a mixture of sand and clay. The casuarina, which had so often been admired by us, entirely disappeared and the channel in many places became so narrow as to be completely arched over by gum-trees. A TRIBE OF NATIVES. On the 16th, we fell in with a numerous tribe of natives who joined our train after the very necessary ceremonies of an introduction had passed, and when added to those who still accompanied us, amounted to fifty-three. On this occasion I was riding somewhat in front of the party, when I came upon them. They were very different in appearance from those whom we had surprised at the river; and from the manner in which I was received, I was led to infer that they had been informed of our arrival, and had purposely assembled to meet us. I was saluted by an old man, who had stationed himself in front of his tribe, and who was their chief. Behind him the young men stood in a line, and behind them the warriors were seated on the ground. CONDUCT OF THE NATIVES.
