The number of accidents that have happened from trivial causes, renders it necessary to be extremely cautious in regard to smoking; which in all men of war, and India-ships, is permitted only on the fore-castle. By this means danger is avoided, and the stench carried away. It is to be lamented that so proper a regulation is not observed throughout the merchant service; in which so much carelessness prevails, that it appears to me miraculous so many vessels arrive in safety. On my return from India, I embarked at St. Helena on board a whaler, of which the captain had a strong predilection for his pipe, which was scarcely ever out of his mouth. His practice was, to smoke in the cabin where we dined, throwing his hot ashes down upon the deck, in which was a skuttle, or small hatchway, under his own seat. Two lieutenants of the navy, who were fellow-passengers, used to remonstrate very freely, but without the smallest effect, against so improper a practice. It happened, one morning, as we were off the Azores, that a suspicious-looking vessel hove in sight, laying-to under close reefed top-sails: we altered our course, and were immediately chased. Having at least forty-five young fellows, and about a dozen six-pounders, on board, we cleared ship for action. Imagine what was our surprise at finding that, under the identical hatchway, over which our captain had been perpetually smoking, was a magazine of about thirty barrels of gun-powder; some hooped in, and some having their chimes barely covering their contents which proved to be ready-filled cartridges! I conceive it would have been utterly impossible, if the vessel in chace had proved an enemy, and that we had been compelled to defend our ship, to have avoided being blown up! Many are in the habit of reading by candle light in their beds: this only requires to be known to the officers, to be completely overruled; nor will they, unless in cases of indisposition, allow a candle to be burning after the passengers have generally retired to rest. Hence, only a few wax tapers, or bougies, can be requisite. When it is considered, that a ship is composed of materials for the chief part highly combustible, and, that in such a situation a fire spreads with astonishing rapidity, defying the exertions of all on board; also, that there is little chance of many lives being saved, unless other vessels may be in company; we ought assuredly to adopt every means of guarding against so terrible a calamity!
