Spanish fill up the First, with a large mixture of native Americans; but the Third Municipality is entirely French and Spanish. It was impossible for me to ascertain how many streets run through the city, but there are many. No fault can be found of the topography of Orleans, and it is strange that the regularity of the thorough fares should have been so well preserved under all the changes and vicissitudes through which she has passed. Everything is of interest here; even the names of the streets attract the notice of the visitor; and as he rides along, he may trace the different races who have formed and named them. He will pass through streets which the descendants of Spain first laid out, such as Esplanade, Ferdinand Casacalvo, Morales, and Perdido. Again his eye will glance at French names, such as Josephine, Bourbon, Chartres, Notre Dame, Dauphin, and Toulouse. Then there are various streets bearing the names of all the saints known to the Catholic devotee. In respect to names very little of Orleans has been Americanized. Occasionally you will meet with such names as Commerce and Canal, which doubtless sound very vulgar to the the French. But the master street of the world is the great Levee, usually from two to five hundred feet wide from the river to the buildings. From this great thoroughfare all others diverge, and it is the greatest mart of its extent in the world. While I was there, THIRTY-SIX THOUSAND BARRELS OF FLOUR were sold in a few hours! And while this astonishing transfer was going on, thousands of other produce and commodities were changing hands. Many years ago it was used as a fashionable promenade to enjoy the breezes of the Mississippi. Commerce has changed its character entirely. Now scenes of the most intensely exciting character are upon the Levee. The very air howls with an eternal din and noise. Drays and wagons of all descriptions, loaded with the produce of every clime, move on continually in one unbroken chain. Ships from every nation, whose masts tower aloft in a dense forest for five miles, with thirty thousand sailors and stevedores, busily loading and unloading, stand in your view. Steamboats, and crafts of every make and shape, from every river which empties into the Mississippi, are here mingling in the strife of commerce. The rough and homely produce of the far and cold Iowa--of the distant Wisconsin--of the black and stormy Northern Lakes, is here thrown upon the Levee in hurry and confusion mingled and mixed with the sweets and luxuries of the sunny tropics. Here, too, the various races of men astonish one. The Kentuckian with an honest and ruddy face; the Yankee with his shrewd and enterprising look; the rich planter of Mississippi; the elegant and chivalrous Carolinian; the sensible and honest citizen from the "Old North State;" the lively, fine-looking, and smart Georgian; the talented and handsome Virginian; the swarthy creole sugar planter; the rough hunter
