The city proper is, by the river, five miles long, and will average three-fourths of a mile wide. Then commences Lafayette, which extends up the river two miles further, and, as they are so intimately connected and associated, it all may be considered as one vast place, seven miles in extent. After a succession of splendid mansions, farms, and other houses, the whole resembling a continued village, Bouligny and Carrollton unite with the chain of commerce. A century from this date, Orleans, like London, will reach out her arms and encompass within her limits every town and hamlet for miles around. As London swallowed up Westminster, Southwark, Lambeth, and Chelsea, so will Lafayette, Bouligny, Carrollton, and others adjacent be lost in her future immensity. It will then all be New Orleans, the largest city on the continent of America, and perhaps in the world. The foundation consists of a plain inclining from the river, and when looking from the St. Charles to the Levee, the singular spectacle is presented of ships and boats standing raised up before you, and the little rivulet in the street, just after a rain, running in a smart current by you and losing itself in the swamp, as if afraid to mingle with the "Father of Waters." As health and cleanliness are greatly promoted by this gentle inclined plain, it is most fortunate that Orleans is so situated. In ancient times the inhabitants were either amphibious or lived at great sufferance from the floods. But now they are protected by the Levee. A stranger however, upon the impulse, would think that protection uncertain. But if he would reflect for a moment, he would wisely determine that it requires not a very strong dyke to pen up the surplus water during a freshet, for the main current is confined by immense banks reaching far, far below. To render my position more palpable, suppose the river should suddenly dry up, Orleans would then be standing on a bluff three hundred and sixty feet high, for that is the depth of the river opposite the city. The foundation, a low alluvial bottom, has been much improved by draining and filling up. No building is erected without the foundation is made firm by piling with long logs driven down with immense force; but very massive buildings, even with this precaution, will continue to settle. It is said that the St. Charles is two feet lower now than formerly. Three great streets divide the city into municipalities. Between Canal and Esplanade, lies the first Municipality, between Esplanade and the lowest street on the outskirts, far down the river, lies the Third Municipality; and between Canal and Felicity, is the Second. They are wide and beautiful streets, running perfectly straight from the river to the farthest back limits, serving not only as boundaries for municipal purposes, but absolutely separating different races. The everlasting Yankees, with their shrewdness and enterprize, inhabit the Second Municipality; the wealthy French and
