Considering it unsafe to remain longer in this infected city, from the reports that the fever was gaining ground, I now made preparations for leaving New Orleans, and as I had made an engagement to manage the affairs of a gentleman in Florida, during his absence at Washington, I determined to proceed thither with the least possible delay. In furtherance of this object I made inquiries for a conveyance by water to St. Marks, giving the preference to steam. In this object I was, however, disappointed, and was obliged to take a passage on board a brig, about to sail for that obscure port. The vessel was towed down to the balize or mouth of the Mississippi, in company with two others, by a departing steamer, which had on board the mail for Bermuda and St. George's Island. Arrived at the balize, whose banks for several miles are overflowed by the sea, I saw a small fleet of vessels, some outward and some inward bound. Amongst these was a United States ship of war, of great beauty, carrying heavy guns. A boat from this vessel, in charge of an officer, boarded us, and delivered to the captain a sealed packet, which I understood to be a dispatch, addressed to General Taylor, the officer in command of the troops operating against the Indians in Florida. The coast about the balize is low and swampy, and everywhere abounds in rush and cane brakes which give its sea-beach a desolate appearance. These morasses harbour thousands of alligators, whose roar had a singular effect as it rose above the breeze. Flocks of aquatic birds were to be seen on every side, the most numerous being the pelican, and a bird of the cotinga species, about the size of an English throstle, the plumage of which, being jet black and flamingo red, had a beautiful effect in the sunshine, as they flew or settled in thousands on the canes. Our passage across the Gulf of Mexico was a favourable one, but when within forty miles of our destination, the vessel struck on a hidden sand-bank. The fog was so dense, that the captain had been mistaken in his reckoning, and had taken a wrong course. For a considerable time we were in great jeopardy, and every attempt to get the ship again afloat was unavailing; and, had not the weather been moderate, there is little doubt but that she would have been lost, and our lives placed in great peril. After some hours' exertion, during which an anchor was lost, and a quantity of iron thrown overboard, we had the satisfaction to find that the vessel was adrift. This was a great relief to us, for had a gale sprung up in the night, which was closing in, we must have taken to the boat, and abandoned the vessel, a perilous undertaking, from which we all felt too happy to have escaped. I was told by the captain that the coast here abounds with hidden sand-banks of the description we had encountered. This, perhaps, together with the poor harbour accommodation in Florida, accounts for the small size of the vessels which generally trade there.
