The duel is here a matter of such frequent recurrence, that any event of the kind hardly excites an hour's notice; the question is merely "which of them got off?" and with that inquiry the affair usually ends. A Court of Honour, having for its end and aim the amelioration of this system, if not its suppression, has been instituted this very year, and pretty generally subscribed to amongst the young Creoles; but I believe its regulations have not proved very efficacious. At nine o'clock P.M. left Mr. T----s; and walking to the near Levee, got on board the Superior, bound for Cincinnati, but chartered to stop at Natchez. The night was clear, but by far the coldest we have yet had here: the crown of the Levee, thronged with its busy crews, was lighted up by numerous fires, reflecting the hundred great steam-boats loading and unloading here, whilst the air resounded with the cheer of the negro gangs, given in unison to a few low simple notes, but full of wild animation, and, to my thinking, exceeding musical. As we cast off into the midst of the wide stream, the whole bank of the Levee, with the warehouses bordering upon it, looked as though illuminated. _Wednesday,4th._--Up early in my little stateroom, where I have a small French bed, a table, a chair, with a sash-window that opens on to the gallery going round the boat. I find my quarters exceedingly comfortable; but the vibration, owing to the power of the engines, renders it difficult to read, and puts all writing quite out of the question. The river banks are well cleared and very thickly populated, exclusively by French. Passing Donaldsonville, where the _bayou la Fourche_ quits the main river to fall into the Mexican Gulf farther to the southward, we saw the capitol designed for the use of the legislature of Louisiana, but which, after being tenanted for a single session, was left for New Orleans, and is now falling to ruin. Many of the planters' seats are large, well-looking buildings, but they appear neglected and badly kept; indeed the climate renders it very difficult to keep a house in decent order unless it is inhabited all the year round, in which case it stands a chance of as many changes of tenants as a Turkish caravansary. These lands have a reputation for prodigious fertility; at one place, belonging to a General Hampton, two schooners were loading molasses: here I was informed a thousand slaves find employment, bringing in to their employer an enormous revenue. At Baton Rouge a military post of the United States' army, we came upon the first rise in the banks: this place looks over a noble reach and bay; the barracks appeared roomy and outwardly in good order.
