The 'Citizen,' of 498 tons was one of seven ships[1] owned by Mr. Thomas H. Smith, of New York, who had been for many years engaged in the China trade. She had already made two voyages to Canton, and before leaving on her present one, had been newly coppered and 'thoroughly' overhauled, the better to withstand the westerly gales she was likely to encounter on her return passage off the Cape of Good Hope in the winter season. The crew consisted of thirty-two men and boys, with two officers. One of the latter, the second officer, as well as Captain Keen and ten or twelve of the men, had served on board privateers in our last war with Great Britain, while eight sailors had just returned from a three years' cruise in the Pacific, on board the U.S. 74 'Franklin,' Commodore Stewart. As usual at this time with vessels bound on Eastern voyages, the 'Citizen' was well provided with arms and ammunition--not only for the risk of pirates in the Atlantic, to whom her valuable cargo offered great temptation, but from possible mishaps while passing through the Eastern Straits. The cargo consisted of 350,000 Spanish dollars in kegs (no letters of credit on London bankers then existing), furs, lead, bar and scrap iron, and quicksilver. Passengers were not taken except under peculiar circumstances. I should have been the only one, in virtue of being destined for Mr. Smith's Factory at Canton, but just before sailing a Scotch gentleman presented himself at the office, and sought for a passage on board. The letters he bore were of a high character, among them being one from the celebrated Mr. Hume. His name was Fullerton, and his vocation that of surgeon in the English East India Company's service. He was allowed to go in the ship, and proved to be a most intelligent and amiable person. He had made several voyages to India and China, was full of anecdote and pleasant conversation, thereby relieving the weariness of the journey. The medical advice he most cheerfully gave rendered him a valuable addition to us, particularly on the occasion of the ship taking fire just before making Sandalwood Island, when one of the men was so seriously injured that his life was despaired of for a time; but although he managed to get back in the ship to New York, he never did a day's work after the accident. My fellow-passenger was only known on board as Doctor Smyth. He had come to New York expressly to get to China in an 'out of season' vessel, which ours was. We had no idea of the object he had in view, and he volunteered no information. There was, however, a little mystery in the matter.
