September 4.—Making a very early start, we travelled twenty miles to the watercourse, where we had encamped on the 31st of August, striking it a little lower down. As I had left one or two trifles here, that I wished to take on with me, I sent the black boy for them, telling him to follow my tracks while I went slowly on. Upon finding that he did not overtake me so soon as I expected, I halted for some time, but still he did not come up, and I again proceeded; for as I had left my former track, I concluded he had taken that line, and thus missed me. Steering, therefore, across the hills, some of which were very stony and broken, I made for the Mundy, which I reached very late in the evening, and found the party safely encamped there.

I had rode fifty–five miles, and had been on horseback about thirteen hours, so that both myself and horse were well nigh knocked up. The black boy had not arrived, nor did he come up during the night.

The next day, becoming uneasy about his absence, I detained the party in the camp, and sent Mr. Scott to search for him, who fortunately met him almost immediately he had left us. The boy’s detention had been occasioned by the fagged condition of his horse, which prevented the possibility of his overtaking me. As the day was wet, I did not move on, but gave the party a day’s rest, whilst I employed myself in meditating upon the disappointment I had experienced, and the future steps it might be most advisable to take to carry out the objects of the expedition. I was still determined not to give up the undertaking,—but rather to attempt to penetrate either to the eastward or westward, and to try to find some other line of route that might afford a practicable opening to the interior.
