The augmentation of our population with the expansion of our Union and increased number of States have produced effects in certain branches of our system which merit the attention of Congress. Some of our arrangements, and particularly the judiciary establishment, were made with a view to the original thirteen States only. Since then the United States have acquired a vast extent of territory; eleven new States have been admitted into the Union, and Territories have been laid off for three others, which will likewise be admitted at no distant day. An organization of the Supreme Court which assigns to the judges any portion of the duties which belong to the inferior, requiring their passage over so vast a space under any distribution of the States that may now be made, if not impracticable in the execution, must render it impossible for them to discharge the duties of either branch with advantage to the Union. The duties of the Supreme Court would be of great importance if its decisions were confined to the ordinary limits of other tribunals, but when it is considered that this court decides, and in the last resort, on all the great questions which arise under our Constitution, involving those between the United States individually, between the States and the United States, and between the latter and foreign powers, too high an estimate of their importance can not be formed. The great interests of the nation seem to require that the judges of the Supreme Court should be exempted from every other duty than those which are incident to that high trust. The organization of the inferior courts would of course be adapted to circumstances. It is presumed that such an one might be formed as would secure an able and faithful discharge of their duties, and without any material augmentation of expense.
