During the whole night we were surrounded by a squadron of boats, which, with lanterns lighted, and drums beating, continually moved round the ship, to intercept any boat leaving it. The captain, finding that the suspicious character of the Japanese would prevent any thing like correct surveying, which was the principal object of his visit to Nagasaki, determined upon leaving this inhospitable shore of Japan as soon as possible. On Sunday the 6th, we weighed, and although the weather was unfavourable, contrived to work out of soundings until 3 P. M., when we made sail for Loo-Choo. At daylight we found ourselves abreast of a burning volcano. Dense clouds of smoke were issuing from a peaked island, about three miles distant. We soon afterwards landed upon an adjacent island, which, to our surprise, also began to smoke. The day was sultry, and without a breath of air, so that in a short time, the atmosphere we were in became overpowering; at last a fresh breeze sprang up, and the disagreeable sensation wore off. The whole of the islands between Loo-Choo and Japan appear to be volcanic, and at certain seasons of the year they break out in a similar manner to those which we saw. At noon the smoke from the large volcano became lurid; but whether this was the breaking out into flame, or from the rays of the sun pouring down upon the smoke, it was impossible to say, as we were then several miles off. During the whole of the following night we were becalmed, and during that time impelled, by a strong current, towards the volcanic island. Strange noises were heard, and large columns of smoke ascended from the crater, which, from there not being a breath of air, soon enveloped it from our sight. On the following day we again landed upon an island, some little distance to the southward of the volcano, which now vomited flames, ashes, and smoke, during the whole day. The master landed on another of these volcanic islands, but the showers of ashes and suffocating atmosphere soon drove him away.
