In the case of the American Insurance Company _v_. Canter, he asserted the right of the government to enlarge the national domain, saying: "The Constitution confers absolutely on the government of the Union the power of making war and of making treaties; consequently, that government possesses the power of acquiring territory, either by conquest or by treaty." But he held the rights of private property in such case to be inviolate (U.S. _v_. Percheman). The most luminous exposition of discovery as a source of title, and of the nature of Indian titles, is to be found in one of his opinions (Johnson _v_. McIntosh). A fundamental doctrine of international law is that of the equality of nations. If a clear and unequivocal expression of it be desired, it may be found in the opinion of Marshall in the case of "The Antelope." "No nation," he declared, "can make a law of nations. No principle is more universally acknowledged than the perfect equality of nations. Russia and Geneva have equal rights." And when the representatives of the United States fifty years later sought to establish at Geneva the liability of Great Britain for the depredations of the "Alabama" and other Confederate cruisers fitted out in British ports in violation of neutrality, one of the strongest authorities on which they relied was his opinion in the case of the "Gran Para." In the decision of prize cases, Marshall, unlike some of his associates, was disposed to moderate the rigor of the English doctrines, as laid down by Sir William Scott. "I respect Sir William Scott," he declared on a certain occasion, "as I do every truly great man; and I respect his decisions; nor should I depart from them on light grounds; but it is impossible to consider them attentively without perceiving that his mind leans strongly in favor of the captors." This liberal disposition, blended with independence of judgment, led Marshall to dissent from the decision of the court in two well-known cases. In one of these, which is cited by Phillimore as the "great case" of "The Venus," it was held that the property of an American citizen domiciled in a foreign country became, on the breaking out of war with that country, immediately confiscable as enemy's property, even though it was shipped before he had knowledge of the war. Marshall dissented, maintained that a mere commercial domicile ought not to be presumed to continue longer than the state of peace, and that the fate of the property should depend upon the conduct of the owner after the outbreak of the war, in continuing to reside and trade in the enemy's country or in taking prompt measures to return to his own. In the other case--that of the "Commercen"--he sought to disconnect the war in which Great Britain was engaged on the continent of Europe from that which she was carrying on with the United States, and to affirm the right of her Swedish ally to transport supplies to the British army in the Peninsula without infringing the
