“ In the United States the boundaries of the Congressional district in each State are determined by the State Legislature after the apportionment of representation has been made by Congress, following on every decennial census. The ratio of representation under the census of 1900 was 194,182, and the total number of Congressional districts 386. There is no definite principle laid down for the manner in which a State may be redistributed, and as a rule the party in power will, as far as possible, so distribute representation as to insure its continued supremacy. ”
