The Black Hawk War opened a new chapter in the history of the Northwest. The soldiers carried to their homes remarkable stories of the richness and attractiveness of the northern country, and the eastern newspapers printed not only detailed accounts of the several expeditions but highly colored descriptions of the charms of the region. Books and pamphlets by the score helped to attract the attention of the country. The result was a heavy influx of settlers, many of them coming all the way from New England and New York, others from Pennsylvania and Ohio. Lands were rapidly surveyed and placed on sale, and surviving Indian hunting-grounds were purchased. Northern Illinois filled rapidly with a thrifty farming population, and the town of Chicago became an entrepôt. Further north, Wisconsin had been organized, in 1836, as a Territory, including not only the present State of that name but Iowa, Minnesota, and most of North and South Dakota. As yet the Iowa country, however, had been visited by few white people; and such as came were only hunters and trappers, agents of the American Fur and other trading companies, or independent traders. Two of the most active of these free-lances of early days--the French Canadian Dubuque and the Englishman Davenport--have left their names to flourishing cities. To recount the successive purchases by which the Government freed Iowa soil from Indian domination would be wearisome. The Treaty of 1842 with the Sauks and Foxes is typical. After a sojourn of hardly more than a decade in the Iowa country, these luckless folk were now persuaded to yield all their lands to the United States and retire to a reservation in Kansas. The negotiations were carried out with all due regard for Indian susceptibilities. Governor Chambers, resplendent in the uniform of a brigadier-general of the United States army, repaired with his aides to the appointed rendezvous, and there the chiefs presented themselves, arrayed in new blankets and white deerskin leggings, with full paraphernalia of paint, feathers, beads, and elaborately decorated war clubs. Oratory ran freely, although through the enforced medium of an interpreter. The chiefs harangued for hours not only upon the beautiful meadows, the running streams, the stately trees, and the other beloved objects which they were called upon to surrender to the white man, but upon the moon and stars and rain and hail and wind, all of which were alleged to be more attractive and beneficent in Iowa than anywhere else. The Governor, in turn, gave the Indians some good advice, urging them to live peaceably in their new homes, to be industrious and self-supporting, to leave liquor alone, and, in general, to "be a credit to the country." When every one had talked as much as he liked, the treaty was solemnly signed.
