These river towns developed and increased in importance as the river trade became an ever increasing object of importance. Pittsburg and Cincinnati were by far the two greatest commercial and manufacturing centers of this western country during the years 1811-1830. As this great stream of emigrants poured into the West, the soil was brought into cultivation, and its surplus produce exchanged for articles of home and foreign manufacture.
