Carlyle said that the Roman republic was allowed so long a day because on emergencies the constitution was suspended by a dictatorship. The American republics have a right, upon this theory, to a still longer one. With them the Constitution need not be temporarily set aside on an emergency. It may simply be permanently enlarged or limited by judicial construction. A Constitution is the garment which a nation wears. Whether written or unwritten, it must grow with its growth. As Mr. Bryce has put it: "Human affairs being what they are, there must be a loophole for expansion or extension in some part of every scheme of government; and if the Constitution is Rigid, Flexibility must be supplied from the minds of the Judges."[Footnote: "Studies in History and Jurisprudence," 197.] The Constitution of the United States declares that no State shall pass any law impairing the obligation of contracts. This proposition being the major premise, Chief Justice Marshall added the minor premise that every charter of a private corporation is a contract, and completed the syllogism by the conclusion that no State can pass any law impairing the obligation of such charters. The counsel who opposed this doctrine urged that every one must acknowledge that neither the men who framed the Constitution nor the people who adopted it ever thought that the word "contracts," as so used, embraced "charters." Be it so, was Marshall's answer, that proves nothing unless you can go farther and satisfy the court that if they had contemplated the construction we put upon it they would have used words to exclude it.[Footnote: Dartmouth College _v._ Woodward, 4 Wheaton's Reports, 518.] The acquisition of foreign territory is a matter not especially provided for in the Constitution of the United States. Jefferson hesitated to make the Louisiana purchase on this account, and was quite inclined to think, when he did make it, that he had transcended the bounds of his authority. The courts gave the Constitution a different interpretation, and stamped this upon it as permanently as if it had been a birthmark. It was done by Marshall in a single sentence. "The Constitution," he observed, "confers absolutely on the government of the Union the powers of making war and of making treaties: consequently that government possesses the power of acquiring territory either by conquest or by treaty."[Footnote: American Insurance Co. _v._ Canter, 1 Peters' Reports, 511, 542.]
