June 1.--Mr. Gilbert and Charley made an excursion down the river last night, to look for water, but, as they did not return in the morning, and as water had been found, after they left, about four miles lower down, we started to meet them. Observing a swarm of white cranes circling in the air, and taking their flight down the river, I concluded that we should meet with a good supply of water lower down, and, therefore, passed the nearest water-hole; but, the country and the bed of the river being exceedingly rocky, our progress was very slow. After proceeding about eight miles, we came to the junction of a river from the south-west with the Lynd; and encamped at some small pools of water in latitude 17 degrees 45 minutes 40 seconds: having travelled, during the last two stages, in a west-north-west direction. June 2.--When we left our camp this morning, Mr. Gilbert and Charley returned from their ride; they had come on our tracks last night, but, surrounded as they were by rocky hills and gullies, had been compelled to encamp. We travelled about seven miles and a half, and crossed three good sized creeks, joining the Lynd from the north east. The river divided several times into anabranches, flowing round, and insulating rocky hills and ridges. It was much better supplied with water, and contained several large reedy lagoons. An elegant Acacia, about thirty or thirty-five feet high, grew on its small flats: it had large drooping glaucous bipinnate leaves, long broad pods, and oval seeds, half black, and half bright red.
