March 10.--At five we were again on our route, every moment expecting to see a break in the line of cliffs along which we had now travelled so far. Alas! they still continued stretching as far as the eye could see to the westward, and as fast as we arrived at one point which had bounded our vision (and beyond which we hoped a change might occur), it was but to be met with the view of another beyond. Distressing and fatal as the continuance of these cliffs might prove to us, there was a grandeur and sublimity in their appearance that was most imposing, and which struck me with admiration. Stretching out before us in lofty unbroken outline, they presented the singular and romantic appearance of massy battlements of masonry, supported by huge buttresses, and glittering in the morning sun which had now risen upon them, and made the scene beautiful even amidst the dangers and anxieties of our situation. It was indeed a rich and gorgeous view for a painter, and I never felt so much regret at my inability to sketch as I did at this moment. Still we kept moving onwards and still the cliffs continued. Hour after hour passed away, mile after mile was traversed, and yet no change was observable. My anxiety for the party who were to follow behind with the pack-horses became very great; the state of doubt and uncertainty I was in was almost insupportable, and I began to fear that neither sheep nor horses would ever reach the water, even should we suceeed in doing so ourselves, which now appeared to be very doubtful. At noon I considered we had come one hundred and ten miles from the last water, and still the country remained the same. The cliffs indeed appeared to be gradually declining a little in elevation to the westward, but there was nothing to indicate their speedy termination. Our sheep still travelled, but they were getting so tired, and their pace was so slow, that I thought it would be better to leave them behind, and by moving more rapidly with the horses endeavour at least to save their lives. Foreseeing that such a contingency as this might occur, I had given the overseer strict orders to keep the tracks of my horses, that if I should be compelled to abandon the sheep he might find them and bring them on with his party.
