The progress of the United States of America, from the earliest periods, geographical, statistical, and historical . which lies southerly of the valley of the WisconsinRiver, comprises the whole of the slope toward Lake Michigan. In many portions of this district the lime rock dis-appears, and the out-cropping standalone furnishes a fine material for Lmilding. The lead-bearing rock of the mineralregion is a porous limestone, prevailing throughout Grant, Lafayette, and Iowa counties, comprising four-fifths of thelead district of the Upper Mississippi,the remaining one-fifth being in the States of Illinois and Iowa. Deposits ofiron ore, water limestone, and beds of gypsum together with other varieties of minerals, are found in localities moreor less numerous throughout the limestone region. All of that section of the State which lies between Lake Superior onthe north and the Falls of St. Anthony on the Mississippi, and the falls of the other rivers flowing southerly, is primitivein its prevailing geological character; and it is within this primitive region that the copper mines of Lake Superior are293. THE STATE OF WISCONSIN. found—probably the richest in the world, and apparently inexhaustible. In all that portion of the State lying betweenthe primitive region just described and the limestone formation of the south and east, the transition sandstone prevails,interspersed with limestone and more sparsely with rock of a primitive character. This formation comprises that sectionof the country drained by the Wisconsin and other rivers tributary to the Upper Mississippi and below the falls of thosestreams. Within this geological district are found quarries of white marble, which promise to be abundant and valuable. Wisconsin, says J. A. Lapham, Esq., does not fall behind the other portions of the Western country in the monu-ments it affords of the existence of an ancient people who once inhabited North America, but of whom nothing is knownexcept what can be gathered fro
