A pictorial description of the United States; embracing the history, geographical position, agricultural and mineral resources .. . e to a thick forest in thisway, in thirteen years. The following general geological stra-ta are fi)und in the whole of the easternupper Mississippi country, as truly as inIowa : 1st, vegetable mould, eight tothirty inches ; 2d, pure yellow clay, threeto eight feet; 3d, gravelly clay with peb-bles, four to ten feet; 4th, limestone, twoto twelve feet; 5th, shale; 6th, bitumi-nous coal ; 7th, soapstone; 8th, sand-stone. The limestone exists every-where. Every well and other excava-tion, which penetrates deep enough,discloses it, and it is exposed by manystreams. The western pait of Iowa is chieflymountain limestone, with strata of fossilchalk formations, wholly or chiefly ofshells. Such is the summit of the bluffat Burlington, and of this is formed thefine whitish marble of Iowa City. Inthe south, between the Des Moines andIowa rivers, are several varieties of mar-ble, some of them black, variegated, & and cornelians are washed out onthe banks of the Mississippi in The state of Wisconsin is bound-ed north by Lake Superior and thenorthern peninsula of Michigan ; eastby Lake Michigan ; soulli by Illinois ;and west by Iowa and the territory ofMinnesota. It lies between 42° 30and 47° north latitude, and 87° and92° 30 west longitude. The lenglhis about three hundred miles, andthe bieadth two hundred, containingabout fifty-four thousand square population in 1840, was 30,945,and in 1S50, 304,121. Those parts ofthe state that lie south of Green Bay,Fox river, and the Wisconsin, present a variety of prairie and timber land, withsome swamps and wet prairies, and a rich soil, varying from one foot to ten feet indepth. The north part is mountainous, declining into hills and a swelling surface,which terminates at Wisconsin river. The streams in that part of the state areoften wild, and much broken by falls and rapids.
