_Taxation and Commerce._--There were none bold enough to dissent from the proposition that revenue must be provided to pay current expenses and discharge the public debt. When once the dispute over the apportionment of direct taxes among the slave states was settled, it was an easy matter to decide that Congress should have power to lay and collect taxes, duties, imposts, and excises. In this way the national government was freed from dependence upon stubborn and tardy legislatures and enabled to collect funds directly from citizens. There were likewise none bold enough to contend that the anarchy of state tariffs and trade discriminations should be longer endured. When the fears of the planting states were allayed and the "bargain" over the importation of slaves was reached, the convention vested in Congress the power to regulate foreign and interstate commerce. _National Defense._--The necessity for national defense was realized, though the fear of huge military establishments was equally present. The old practice of relying on quotas furnished by the state legislatures was completely discredited. As in the case of taxes a direct authority over citizens was demanded. Congress was therefore given full power to raise and support armies and a navy. It could employ the state militia when desirable; but it could at the same time maintain a regular army and call directly upon all able-bodied males if the nature of a crisis was thought to require it. _The "Necessary and Proper" Clause._--To the specified power vested in Congress by the Constitution, the advocates of a strong national government added a general clause authorizing it to make all laws "necessary and proper" for carrying into effect any and all of the enumerated powers. This clause, interpreted by that master mind, Chief Justice Marshall, was later construed to confer powers as wide as the requirements of a vast country spanning a continent and taking its place among the mighty nations of the earth. =Restraints on the States.=--Framing a government and endowing it with large powers were by no means the sole concern of the convention. Its very existence had been due quite as much to the conduct of the state legislatures as to the futilities of a paralyzed Continental Congress. In every state, explains Marshall in his _Life of Washington_, there was a party of men who had "marked out for themselves a more indulgent course. Viewing with extreme tenderness the case of the debtor, their efforts were unceasingly directed to his relief. To exact a faithful compliance with contracts was, in their opinion, a harsh measure which the people could not bear. They were uniformly in favor of relaxing the administration of justice, of affording facilities for the payment of debts, or of suspending their collection, and remitting taxes."
