3d. To "regulate commerce with foreign nations, and among the States, and with the Indian tribes." To erect a bank, and to regulate commerce, are very different acts. He who erects a bank, creates a subject of commerce in its bills; so does he who makes a bushel of wheat, or digs a dollar out of the mines; yet neither of these persons regulates commerce thereby. To make a thing which may be bought and sold, is not to prescribe regulations for buying and selling. Besides, if this was an exercise of the power of regulating commerce, it would be void, as extending as much to the internal commerce of every State, as to its external. For the power given to Congress by the Constitution does not extend to the internal regulation of the commerce of a State, (that is to say of the commerce between citizen and citizen,) which remain exclusively with its own legislature; but to its external commerce only, that is to say, its commerce with another State, or with foreign nations, or with the Indian tribes. Accordingly the bill does not propose the measure as a regulation of trade, but as "productive of considerable advantages to trade." Still less are these powers covered by any other of the special enumerations.
