When the reader reflects that this immense city is assisted by twenty thousand miles of river navigation, extending into all parts of the western country, which is a world of itself, added to the commerce which it enjoys through the lakes and the great gulf, he will not be surprised in casting his eye over the following items: Number of ships which arrived in 1846, 743; barks, 377; brigs 447; schooners, 518; flatboats, 2670; arrivals of steamboats, 2763. There are 550 steamboats employed in the river navigation. The value of produce exported was $72,000,000; of imports, $35,000,000. Number of lawyers, 300; physicians, 200; commission merchants, 560. This statement proves the commerce of Orleans to be very great, but it must be borne in mind that it is constantly on the increase, and no calculations can be made upon it in future, as to where it will stop. Mississippi, Tennessee, Kentucky, Ohio, Illinois, Indiana, Michigan, Missouri, Iowa, Wisconsin, are all yearly increasing in population and produce; the latter of which must find a market here. Then I may add the product of another world not hitherto contributing, the whole western part of the valley, from the extreme north-western base of the Rocky Mountains, far, far down to the mouth of the Rio Grande, embracing the whole of Texas, all the Santa Fé territory, and the vast regions now inhabited by the Cherokees, Foxes, Creeks, Osages, and other tribes, who roam in "wilds immeasurably spread." "The country tributary to Orleans" so Norman says, "contains nearly as many square miles and more tillable ground than all of continental Europe, and if peopled as densely as England, would sustain a population of five hundred millions." He is hardly large enough in his conceptions. Who can tell the future size of the Crescent City? None but HIM who numbers the sands on the sea shore, and notices the sparrows as they fall!
