This morning our bridge was no longer to be seen, the river having risen so much during the night that it was four feet under water. Yet no rain had fallen for five days previous, and we could account for this unexpected flood only by supposing that the powerful shining of the sun during the last two days had melted the snow near the sources of the stream. At noon the water had risen fourteen feet. A whispering sound much resembling wind among the trees now arose from it and, however inconvenient to us, the novelty of a sudden rise in the river was quite refreshing, accustomed as we had been so long to wander in the beds of rivers and to seek in vain for water. Our little bridge continued to be passable even when covered with four feet of water but, as it had no parapets, we could not prevent some of the bullocks from going over the side on attempting to cross when it was thus covered. THEN CROSS IT IN BOATS. The river still continuing to rise, we were compelled at last to launch the boats, and by this means we effected the passage of the whole party and equipment before sunset; the boats having been also again mounted on the carriage the same evening. The carts and boat-carriage were drawn through the bed of the river by means of the drag-chains which reached from the carriage on one side to a strong team of bullocks on the other. USEFUL ASSISTANCE OF PIPER. This was a very busy day for the whole party, black and white; I cannot fairly say savage and civilised for, in most of our difficulties by flood and field, the intelligence and skill of our sable friends made the whitefellows appear rather stupid. They could read traces on the earth, climb trees, or dive into the water better than the ablest of us. In tracing lost cattle, speaking to the wild natives, hunting, or diving, Piper was the most accomplished man in the camp. In person he was the tallest, and in authority he was allowed to consider himself almost next to me, the better to secure his best exertions. When Mr. Stapylton first arrived Piper came to my tent and observed that "That fellow had TWO coats," no doubt meaning that I ought to give one of them to him! The men he despised, and he would only act by my orders. This day he rendered us much useful assistance in the water; for instance, when a cart stuck in the bottom of the river, the rope by which it was to be drawn through having broken, Piper, by diving, attached a heavy chain to it, thereby enabling the party to draw it out with the teams.
