In the drawing of boundary lines absurd complications have arisen through failure to conceive the practical geography of a region. Under some general formula like self-determination statesmen have at various times drawn lines on maps, which, when surveyed on the spot, ran through the middle of a factory, down the center of a village street, diagonally across the nave of a church, or between the kitchen and bedroom of a peasant's cottage.
