The regulation of commerce with the Indian tribes is very properly unfettered from two limitations in the articles of Confederation, which render the provision obscure and contradictory. The power is there restrained to Indians, not members of any of the States, and is not to violate or infringe the legislative right of any State within its own limits. What description of Indians are to be deemed members of a State, is not yet settled, and has been a question of frequent perplexity and contention in the federal councils. And how the trade with Indians, though not members of a State, yet residing within its legislative jurisdiction, can be regulated by an external authority, without so far intruding on the internal rights of legislation, is absolutely incomprehensible. This is not the only case in which the articles of Confederation have inconsiderately endeavored to accomplish impossibilities; to reconcile a partial sovereignty in the Union, with complete sovereignty in the States; to subvert a mathematical axiom, by taking away a part, and letting the whole remain. All that need be remarked on the power to coin money, regulate the value thereof, and of foreign coin, is, that by providing for this last case, the Constitution has supplied a material omission in the articles of Confederation. The authority of the existing Congress is restrained to the regulation of coin STRUCK by their own authority, or that of the respective States. It must be seen at once that the proposed uniformity in the VALUE of the current coin might be destroyed by subjecting that of foreign coin to the different regulations of the different States. The punishment of counterfeiting the public securities, as well as the current coin, is submitted of course to that authority which is to secure the value of both. The regulation of weights and measures is transferred from the articles of Confederation, and is founded on like considerations with the preceding power of regulating coin.
