Becanse of these mines the UnitedStates has become the greatest steel-making country in the Manufactures developed in the South. —The growth ofcotton textile manufacture in the South was one of the readjust-ments that was bound to come about in the course of time. Thebuilding of railways, together with the possibilities of good waterpower and cheap fuel, had much to do with bringing the resultabout. The fact that it was very poor economy to send cottona thousand miles away to be manufactured into cloth resulted in. Shipping Iron Ore from the Lake Srikuiok .AIixes. the building of many hundred mills in the South, as soon as theproblems of transportation and fuel were solved. In the amountof cloth made, the output of the Southern mills was not farbehind that of the New England mills at the close of the nine-teenth century. Electrical Inventions. — With the exception of its use in thetelegraph and occasionally in medicine, electricity had not beenused in the various arts and sciences before 1870. Up to thattime there were but two sorts of generators of the electric current,— the frictional machine and the galvanic battery. The former 382 THE MAKING OF THE AMERICAN NATION was nothing more than a toy; the latter was confined to teleg-raphy and medicine. Early in the seventies several inventors set themselves to the task of inventing an electric generator which should produce a current strong enough to operate machinery.^ This m
