The Census of 1870 will cause some important changes. In 1840 the West was represented in Congress by thirty members; after 1870 it will have eighty-two. In the Eastern States a very different result will be produced. Those States in 1840 had thirty-eight members; their representation will be but twenty-two after 1870. In 1840, the Atlantic Eastern States, as divided from the Southern, had one hundred and nineteen Congressmen; after 1870, they will have but eighty-six. More than one third of the next House of Representatives, elected after the census of 1870, will be from the West, and united to the Southwest, will constitute a clear majority of the members of that body as well as of Presidential electors. When the census shall be taken, and apportionment made for the first time in accordance with it, the South will have a full representation upon the negroes, instead of three-fifths of them as now and heretofore. By this the South will gain thirteen members at least. Jersey County Democrat, September 4, 1869
