It is not necessary to dwell much upon the external features of New Orleans, for innumerable descriptions and pictures have familiarized the public with them. Besides, descriptions can give the stranger little idea of the peculiar city. Although all on one level, it is a town of contrasts. In no other city of the United States or of Mexico is the old and romantic preserved in such integrity and brought into such sharp contrast to the modern. There are many handsome public buildings, churches, club-houses, elegant shops, and on the American side a great area of well-paved streets solidly built up in business blocks. The Square of the original city, included between the river and canal, Rampart and Esplanade streets, which was once surrounded by a wall, is as closely built, but the streets are narrow, the houses generally are smaller, and although it swarms with people, and contains the cathedral, the old Spanish buildings, Jackson Square, the French Market, the French Opera-house, and other theatres, the Mint, the Custom-house, the old Ursuline convent (now the residence of the archbishop), old banks, and scores of houses of historic celebrity, it is a city of the past, and specially interesting in its picturesque decay. Beyond this, eastward and northward extend interminable streets of small houses, with now and then a flowery court or a pretty rose garden, occupied mainly by people of French and Spanish descent. The African pervades all parts of the town, except the new residence portion of the American quarter. This, which occupies the vast area in the bend of the river west of the business blocks as far as Carrollton, is in character a great village rather than a city. Not all its broad avenues and handsome streets are paved (and those that are not are in some seasons impassable), its houses are nearly all of wood, most of them detached, with plots of ground and gardens, and as the quarter is very well shaded, the effect is bright and agreeable. In it are many stately residences, occupying a square or half a square, and embowered in foliage and flowers. Care has been given lately to turf-culture, and one sees here thick-set and handsome lawns. The broad Esplanade Street, with its elegant old-fashioned houses, and double rows of shade trees, which has long been the rural pride of the French quarter, has now rivals in respectability and style on the American side.
