January 15.--At sunrise we arrived at the undulating plains, where twenty gallons of water had been left buried for us. Here I found the overseer with two fresh horses, according to the instructions I had sent him on the 6th, by the man who returned. After resting for an hour or two, I set off with the native boy upon the fresh horses, and rode to the water at the sand-drifts, leaving the overseer to bring on the tired animals the next day. It was nearly dark when we arrived at the plain under the sand-hills, and very late before we had watered the horses and brought them back to the grass. January 16.--After breakfast, in returning from the water, we had a feast upon some berries, growing on the briary bushes behind the sand-hills; they were similar to those the natives had offered to us, at the head of the Bight, on the 7th, were very abundant, and just becoming ripe. About eight o'clock we set off for the depot, and arrived there at two, glad to reach our temporary home once more, after eighteen days absence, and heartily welcomed by Mr. Scott, who complained bitterly of having been left alone so long. Under the circumstances of the case, however, it had been quite unavoidable. Upon tasting the water at the well, I found, that from so much having been taken out, it had now become so very brackish, that it was scarcely usable, and I decided upon returning again to Fowler's Bay, where the water was good, as soon as the overseer came back. January 17.--Spent the day in writing, and in meditating upon my future plans and prospects. I had now been forty-five miles beyond the head of the Great Bight, that point to which I had looked with interest and hope; now, I had ascertained that no improvement took place there, in the appearance or character of the country, but, if any thing, that it became less inviting, and more arid. The account of the natives fully satisfied me that there was no possibility of getting inland, and my own experience told me that I could never hope to take a loaded dray through the dreadful country I had already traversed on horseback. What then was I to do? or how proceed for the future? The following brief abstract of the labours of the party, and the work performed by the horses in the three attempts made to get round the head of the Great Bight, may perhaps seem incredible to those who know nothing of the difficulty of forcing a passage through such a country as we were in, and amidst all the disadvantages we were under, from the season of the year and other causes.
