The afternoon proved cloudy, with occasional showers: prepared every thing for our return eastward on the morrow. July 9.--The morning fair and pleasant, but cold, the ground being covered with hoar-frost. At half-past eight we set out on our return eastward, every one feeling no little pleasure at quitting a region which had presented nothing to his exertions but disappointment and desolation. Under a tree near the tent, inscribed with the words "Dig under," we buried a bottle, containing a paper bearing the date of our arrival and departure, with our purposed course, and the names of each individual that composed the party. I cannot flatter myself with the belief, however, that European eyes will ever trace the characters either on the tree or the paper; but we deposited the scroll as a memorial that the spot had been once in the tide of time visited by civilized man, and that should Providence forbid our safe return to Bathurst, the friends who might search for us should at least know the course we had taken. About two o'clock we arrived at our halting-place of the 4th; and there being no place convenient for pitching our tent within six or seven miles farther on, we determined to remain here. July 10.--Observed the variation of the compass by amp., at sun-rising, to be 7. 47. E., by Kater's compass. The horses having strayed, it was nearly eleven o'clock before we could set out, and between four and five o'clock we stopped at our halting-place of the 3d. On our way we passed a raised mound of earth which had somewhat the appearance of a burial-place; we opened it, but found nothing in it except a few ashes, but whether from bones or wood could not be distinguished; a semicircular trench was dug round one side of it, as if for seats for persons in attendance. July 11.--At nine, again set forward on our return up the river, and it was near four o'clock before we arrived at a convenient halting-place on its banks, the river presented a most singular phenomenon to our astonished view. That river which yesterday was so shallow that it could be walked across, and whose stream was scarcely perceptible, was now rolling along its agitated and muddy waters nearly on a level with the banks: whence this sudden rise, we could not divine, any more than we could account for the non-appearance of a fresh twenty miles lower down; unless the marshes which we have traced for the two last days, at a distance from the river, should have absorbed the waters in passing, or unless the extremely winding course should so protract and retard the current of them as to cause a considerable time to elapse before a flood in the upper parts could reach the lower. We considered ourselves as extremely fortunate in having quitted our station of the 8th a day or two before it was originally intended, as we should otherwise have been in considerable danger. The present height of the bank above the level of the stream is four feet nine inches.
