A point or two abaft our beam, within pistol shot distance, slowly and majestically moved a huge, British West Indiaman, her black gloomy hull wholly unrelieved by brighter colours, with her red ensign heavily unfolding to the breeze in recognition of the stars and stripes, floating gracefully at our peak. Farther astern, a taunt-rigged, rakish looking Portuguese polacca (polaque) carrying even in so light a breeze a "bone in her teeth," glided swiftly along, every thing set from deck to truck. We could distinctly see the red woollen caps and dark red faces of her crew, peering over the bow, as they pointed to, and made remarks upon our ship. Early in the morning, about a league ahead of us, we had observed a heavy sailing Dutch ship, as indeed all Dutch ships are; about eleven o'clock we came up with, and passed her, with the same facility as if she had been at anchor. On all sides of us vessels of nearly every maritime nation were in sight; and in conjectures respecting them, and in admiring their variety of construction and appearance, we passed most of the day, elated with the prospect of a speedy termination to our voyage.
Before we had completed dinner, the cry of "Land ho!" was heard from the main-top, and in the course of half an hour we saw from the deck, not exactly _land_, but an apology for it, in the form and substance of an immense marsh of tall, wild grass, which stretched along the horizon from west to east _ad infinitum_. This soil, if you may term it such, is formed by the accumulation and deposition of ochreous matter discharged by the Mississippi, whose turbid waters are more or less charged with terrene particles, so much so, that a glass filled with its water appears to deposit in a short time a sediment nearly equal to one-twelfth of its bulk. The matter discharged by the river, condensed and strengthened by logs, trees, grass, and other gross substances, is raised above the ordinary tide waters, upon which a soil is formed of mingled sand and marl, capable of producing the long grass, which not only lines the coast in the vicinity of this river, but extends many miles into the interior, where it unites with the cypress swamps which cover the greater part of the unreclaimed lowlands of Louisiana. We coasted along this shore till about three in the afternoon, when the light-house at the South-East passage, the chief _embouchure_ of the Mississippi, appeared in sight but a few miles ahead; passing this, we received a pilot from a fairy-like pilot-boat, which, on delivering him, bounded away from us like a swift-winged albatross. About four o'clock the light-house at the South-West passage lifted its solitary head above the horizon. The breeze freshening, we approached it rapidly, under the guidance of the pilot, who had taken command of our ship. When nearly abreast of the light-house, a fierce little warlike-looking revenue cutter ran alongside of us, and lowering her boat, sent her lieutenant on board, to see that "all was straight." He cracked a bottle of wine with the captain, and leaving some late New-Orleans papers, took his departure. For the next half hour the quarter-deck appeared like a school-room--buzz, buzz, buzz! till the papers were read and re-read, advertisements and all, and all were satisfied. About six in the evening we cast anchor at the mouth of the South-West pass, in company not only with the fleet in which we had sailed during the day, but with a large fleet already at anchor, waiting for tide, pilots, wind, or tow-boats. In approaching the mouth of the river, we observed, to us, a novel and remarkable appearance--the meeting of the milky, turbid waters of the Mississippi, with the pale green of the ocean. The waters of the former, being lighter than the latter, and not readily mingling with it, are thrown upon the surface, floating like oil to the depth of only two or three feet. A ship passing through this water, leaves a long, dark wake, which is slowly covered by the uniting of the parted waters. The line of demarkation between the yellowish-brown water of the river, and the clear green water of the sea, is so distinctly defined, that a cane could be laid along it. When we first discovered the long white line, about two miles distant, it presented the appearance of a low sand beach. As we reached it, I went aloft, and seating myself in the top-gallant cross-trees, beheld one of the most singular appearances of which I had ever formed any conception. When within a few fathoms of the discoloured water, we appeared to be rushing on to certain destruction, and when our sharp keel cut and turned up the sluggish surface, I involuntarily shuddered; the next instant we seemed suspended between two seas.
