in the THIRD class are those which provide for the harmony and proper intercourse among the States.
Under this head might be included the particular restraints imposed on the authority of the States, and certain powers of the judicial department; but the former are reserved for a distinct class, and the latter will be particularly examined when we arrive at the structure and organization of the government. I shall confine myself to a cursory review of the remaining powers comprehended under this third description, to wit: to regulate commerce among the several States and the Indian tribes; to coin money, regulate the value thereof, and of foreign coin; to provide for the punishment of counterfeiting the current coin and securities of the United States; to fix the standard of weights and measures; to establish a uniform rule of naturalization, and uniform laws of bankruptcy, to prescribe the manner in which the public acts, records, and judicial proceedings of each State shall be proved, and the effect they shall have in other States; and to establish post offices and post roads.
