When at last (1804) the United States obtained possession of the lands west of the Mississippi, numerous enterprising Americans forced their way into the lead district. They managed to mine a good deal of the metal, here and there, but frequently met with armed opposition from the Indians. It was fifteen years before the Americans equaled the French Canadians in number. In 1819, the Indian claims to the mining country having at last been purchased by the federal government, there was a general inrush of Americans. Among the earliest and most prominent of these was James W. Shull, the founder of Shullsburg, in Iowa county. Another man of note was Colonel James Johnson, of Kentucky, who brought negro slaves into the region, to do his heaviest labor, and maintained a fleet of flatboats to carry lead ore from Galena River to St. Louis, New Orleans, and Pittsburg. At first the operations of Johnson, Shull, and others had to be carried on under military protection; for the Indians, although they had sold their claims, persisted in annoying the newcomers, being urged on by the French miners and traders who were still numerous in the mining country. But so soon as the news spread that a large trade in lead was fast springing up, other Americans began to pour in; mining claims were entered in great numbers, a federal land office was opened, and by 1826 two thousand men, including negro slaves brought in by Kentucky and Missouri operators, were engaged in and about the mines. The following year the town of Galena was founded, and in 1829 there was a stampede thither. Henceforth, for many years, the lead trade of southwestern Wisconsin, northwestern Illinois, and parts of Missouri and Iowa was the chief interest in the West. By this time the fur trade had almost died out, and the old French Canadian element had become but a small proportion of the population of the Mississippi valley. In those days, Galena, Mineral Point, and other lead mining towns were of much more importance than Chicago or Milwaukee, and their citizens entertained high hopes of the future. The lead trade with St. Louis and New Orleans was very large; but the East also wanted the lead, and the air was filled with projects to secure routes by which lead might be carried to vessels plying on the Great Lakes, which could transport it to Buffalo and other far away ports.
