The abundance of white cockatoos and crows, which is constantly about the banks of the river, is astonishing; the other smaller birds appear to be also common to the east coast. Since we have been on the river, no recent traces of the natives have been seen; here, as higher up the river, they rather seem to shun it, and frequent the higher grounds in preference: perhaps their food is more easily procured on those grounds than on the river, particularly as they appear unacquainted with the method of taking the fish by hook and line. As the horses were by no means in a condition to be forced, I determined to remain here to-morrow to refresh them, and set forward again on Saturday morning. June 27.--After breakfast, I sent two men down the river to examine our route for to-morrow: one of them crossed over to the north side, to endeavour to reach some open spaces of plains which we saw from our tent. In the course of the afternoon they both returned; one, who had gone a little way inland on this side, could make no progress for extensive swamps, covered with water of the depth of from two to four feet, and abounding with black swans and wild fowl. The other man was also unable to reach the plains on the other side for water supplied from a creek of the river, and forming an extensive and deep morass. With these unfavourable reports before us, we determined to keep close to this bank of the river during tomorrow's journey; and if we should he prevented by its overflowing from proceeding, to return, and endeavour to round the morasses to the southward. Latitude by observation 33. 22. S., long. 145. 24. 15. E.; and the variation of the compass 7. 30. E. June 28.--Upon farther consideration, it appeared more advisable that the horses should proceed round the south edge of the morasses rather than be obliged to return; after keeping by the river for three or four miles, which to all appearance was as far as we should be enabled to proceed in that direction. However, that there might remain no doubt as to which was the preferable route, I adhered to my determination to go down the banks of the river myself as far as I could, and return by the route which the horses were to take. Our principal object being to keep as close to the stream as possible, with reference to the ability of the horses to travel over the ground.
