_The Legislative Branch--Congress._--After the convention had made the great compromise between the large and small commonwealths by giving representation to states in the Senate and to population in the House, the question of methods of election had to be decided. As to the House of Representatives it was readily agreed that the members should be elected by direct popular vote. There was also easy agreement on the proposition that a strong Senate was needed to check the "turbulence" of the lower house. Four devices were finally selected to accomplish this purpose. In the first place, the Senators were not to be chosen directly by the voters but by the legislatures of the states, thus removing their election one degree from the populace. In the second place, their term was fixed at six years instead of two, as in the case of the House. In the third place, provision was made for continuity by having only one-third of the members go out at a time while two-thirds remained in service. Finally, it was provided that Senators must be at least thirty years old while Representatives need be only twenty-five. _The Judiciary._--The need for federal courts to carry out the law was hardly open to debate. The feebleness of the Articles of Confederation was, in a large measure, attributed to the want of a judiciary to hold states and individuals in obedience to the laws and treaties of the union. Nevertheless on this point the advocates of states' rights were extremely sensitive. They looked with distrust upon judges appointed at the national capital and emancipated from local interests and traditions; they remembered with what insistence they had claimed against Britain the right of local trial by jury and with what consternation they had viewed the proposal to make colonial judges independent of the assemblies in the matter of their salaries. Reluctantly they yielded to the demand for federal courts, consenting at first only to a supreme court to review cases heard in lower state courts and finally to such additional inferior courts as Congress might deem necessary.
