March 28.--AT daylight we moved on, every one walking, even the youngest boy could not ride now, as the horses were so weak and jaded. Soon after leaving the camp, one of them laid down, although the weight upon his back was very light; we were consequently obliged to distribute the few things he carried among the others, and let him follow loose. Our route lay along the beach, as the dense scrub inland prevented us from following any other course; we had, therefore, to go far out of our way, tracing round every point, and following along every bay, whilst the sea-weed frequently obstructed our path, and drove us again to the loose sands, above high water mark, causing extra fatigue to our unfortunate horses. At other times we were forced to go between these banks of sea-weed and the sea, into the sea itself, on which occasions it required our utmost vigilance to prevent the wretched horses from drinking the salt water, which would inevitably have destroyed them. In order to prevent this we were obliged to walk ourselves in the water, on the sea-side of them, one of the party being in advance, leading one horse, another being behind to keep up the rear, and the other three being at intervals along the outside of the line, to keep them from stopping for an instant until the danger was past. We had scarcely advanced six miles from our last night's camp when the little Timor pony I had purchased at Port Lincoln broke down completely; for some time it had been weak, and we were obliged to drive it loose, but it was now unable to proceed further, and we were compelled to abandon it to a miserable and certain death, that by pushing on, we might use every exertion in our power to relieve the others, though scarcely daring to hope that we could save even one of them. It was, indeed, a fearful and heart-rending scene to behold the noble animals which had served us so long and so faithfully, suffering the extremity of thirst and hunger, without having it in our power to relieve them. Five days of misery had passed over their heads since the last water had been left, and one hundred and twelve miles of country had been traversed without the possibility of procuring food for them, other than the dry and sapless remains of last year's grass, and this but rarely to be met with. No rains had fallen to refresh them, and they were reduced to a most pitiable condition, still they travelled onwards, with a spirit and endurance truly surprising. Whenever we halted, they followed us about like dogs wherever we went, appearing to look to us only for aid, and exhibiting that confidence in us which I trust we all reposed in the Almighty, for most truly did we feel, that in His mercy and protection alone our safety could now ever be hoped for.
