Although New Orleans has only about a quarter of a million of inhabitants, and so many only in the winter, it is larger than Pekin, and I believe than Philadelphia, having an area of about one hundred and five square miles. From Carrollton to the Barracks, which are not far from the Battle-field, the distance by the river is some thirteen miles. From the river to the lake the least distance is four miles. This vast territory is traversed by lines of horse-cars which all meet in Canal Street, the most important business thoroughfare of the city, which runs north-east from the river, and divides the French from the American quarter. One taking a horse-car in any part of the city will ultimately land, having boxed the compass, in Canal Street. But it needs a person of vast local erudition to tell in what part of the city, or in what section of the home of the frog and crawfish, he will land if he takes a horse-ear in Canal Street. The river being higher than the city, there is of course no drainage into it; but there is a theory that the water in the open gutters does move, and that it moves in the direction of the Bayou St. John, and of the cypress swamps that drain into Lake Pontchartrain. The stranger who is accustomed to closed sewers, and to get his malaria and typhoid through pipes conducted into his house by the most approved methods of plumbing, is aghast at this spectacle of slime and filth in the streets, and wonders why the city is not in perennial epidemic; but the sun and the wind are great scavengers, and the city is not nearly so unhealthy as it ought to be with such a city government as they say it endures.
