This misfortune had probably been communicated to us by contagion. The homeward-bound ships of the English East India Company, which almost all touch at St. Helena, having nothing in view but a quick passage, and the profit resulting from it, do not generally, as I have myself had opportunities of observing, pay that proper attention to cleanliness and wholesome diet which is absolutely necessary to health. During our residence at St. Helena, several of these ships were lying in the roads with sick on board. It is true that, according to a standing order, no vessel is allowed anchorage there till a surgeon has examined into the state of health of her crew; but the captains find means to evade the investigation, and thus are the healthy liable to become infected by association with the diseased. Half our crew lay sick, and our skilful and active surgeon was unfortunately of the number. A favouring gale, however, sprang up, which carried us into a cooler and drier climate, our invalids quickly recovered, and we escaped with the loss of one sailor only. By the 12th of March, when we passed the Azore Islands, the crew was again in perfect health. On the 3rd of June we reached Portsmouth, where we stopped some days. On the 29th we touched at Copenhagen, and on the 10th of July joyfully dropped our anchor in the roads of Cronstadt, from whence we had sailed nearly three years before. If my readers have by this time become sufficiently acquainted with me to interest themselves in my affairs, they will not learn with indifference, that my most gracious Sovereign the Emperor has honoured me by the most condescending testimonials of his satisfaction, and that after our long separation, I had the gratification of finding my wife and children well and happy.
