We see the Sicilian fruit-seller with his native dialect; the brisk French madame with her dainty stall; the mild-eyed Louisiana Indian woman with her sack of gumbo spread out before her; the fish-dealer with his wooden bench and odd patois; the dark-haired creole lady with her servant gliding here and there; the old Spanish gentleman with the blood of Castile tingling in his veins; the graceful French dame in her becoming toilet; the Hebrew woman with her dark eyes and rich olive complexion; the pure Anglo-Saxon type, ever distinguishable from all others; and, swarming among them all, the irrepressible negro,-- him you find in every size, shape, and shade, from the tiny yellow pickaninny to his rotund and inky grandmother, from the lazy wharf- darky, half clad in both mind and body, to the dignified colored policeman, who patrols with officious gravity the city streets,--in freedom or slavery, north or south, in sunshine or out of it, ever the same easy, improvident race; ever the same gleaming teeth and ready "Yes, sah! 'pon my word, sah!" and ever the same tardiness to DO. Leaving the busy, surging mass of humanity, each so eager to buy or sell, the visitor to New Orleans will find a great contrast of scene in the quiet cemeteries with their high walls of shelves, where the dead are laid away in closely cemented tombs built one over the other, and all above the ground, to be safe from the encroachment of water, the ever-pervading foe of New Orleans. Not only must the dead be stowed away above-ground, but the living must wage a daily war against this insidious foe, and watch with vigilance their levees. Notwithstanding all that has been said in regard to the enervating effects of a southern climate, the inhabitants of the state of Louisiana have shown a pertinacity in maintaining their levee system which is almost unexampled. They have always asserted their rights to the lowlands in which they live, and have under the most trying circumstances braved inundation. They have built more than one thousand five hundred miles of levees within the state limits. The state engineer corps is always at work along the banks of the Mississippi and its important bayous. The work of levee-building has been pushed ahead when a thousand evils beset the community. Accurate and detailed surveys are a constant necessity to prevent inundation. The cost-value of the present system is seven millions of dollars, and as much more is needed to make it perfect. During the civil war millions of cubic feet of levees were destroyed; but the state in her impoverished condition has not only rebuilt the old levees, but added new ones in the intervening years, showing an industry and energy we must all appreciate.
