July 10th.--In the evening a display of fireworks took place, notice of which had been given to the rajah, and, indeed, to the whole population of Kuchin, who had all assembled near to the ship, to witness what they considered a most wonderful sight. Seamen were stationed at all the yard-arms, flying jib, and driver booms, with blue-lights, which were fired simultaneously with the discharge of a dozen rockets, and the great gun of a royal salute. The echoes reverberated for at least a minute after the last gun of the salute had been fired; and, judging by the yells of the natives, the display must have created a strong sensation. Immediately after the salute, the anchor was weighed, and we commenced dropping down the river with the ebb tide; but we soon grounded on the mud, and we remained all night with the bowsprit in the bushes which grow on the banks of the river. The ship floated the next morning; the anchor was weighed, and with the assistance of the ebb tide, we dropped down the river at the rate of five miles per hour. As we were nearing a cluster of dangerous rocks, about a mile below Kuchin, we found that the ship was at the mercy of the rapid tide; and, notwithstanding all our endeavours, the ship struck on the rocks. Anchors were immediately laid out, but to no effect: the water rapidly shallowed, and we gave up all thoughts of getting off until the next flood tide. As the water left the ship, she fell over to starboard, and, an hour after she had grounded, she listed to starboard 25 degrees. Our position was now becoming critical: the main deck ports had been shipped some time previous, but this precaution did not prevent the water from gaining entrance on the main and lower decks. As she still continued to heel over to starboard, a hawser was taken on shore, and, by purchases, set taut to the mast head; but before this could be accomplished she had filled so much that it proved useless.
