illustration of this universal principle of institutional change. There has been a constant growth of legislative and administrative practice, and a steady accretion of precedent in the management of federal affairs, which have broadened the sphere and altered the functions of the government without perceptibly affecting the vocabulary of our constitutional language. Ours is, scarcely less than the British, a living and fecund system. It does not, indeed, find its rootage so widely in the hidden soil of unwritten law; its tap-root at least is the Constitution; but the Constitution is now, like Magna Carta and the Bill of Rights, only the sap-centre of a system of government vastly larger than the stock from which it has branched,--a system some of whose forms have only very indistinct and rudimental beginnings in the simple substance of the Constitution, and which exercises many functions apparently quite foreign to the primitive properties contained in the fundamental law. The Constitution itself is not a complete system; it takes none but the first steps in organization. It does little more than lay a foundation of principles. It provides with all possible brevity for the establishment of a government having, in several distinct branches, executive, legislative, and judicial powers. It vests executive power in a single chief magistrate, for whose election and inauguration it makes carefully definite provision, and whose privileges and prerogatives it defines with succinct clearness; it grants specifically enumerated powers of legislation to a representative Congress, outlining the organization of the two houses of that body and definitely providing for the election of its members, whose number it regulates and the conditions of whose choice it names; and it establishes a Supreme Court with ample authority of constitutional interpretation, prescribing the manner in which its judges shall be appointed and the conditions of their official tenure. Here the Constitution's work of organization ends, and the fact that it attempts nothing more is its chief strength. For it to go beyond elementary provisions would be to lose elasticity and adaptability. The growth of the nation and the consequent development of the governmental system would snap asunder a constitution which could not adapt itself to the new conditions of an advancing society. If it could not stretch itself to the measure of the times, it must be thrown off and left behind, as a by-gone device; and there can, therefore, be no question that our Constitution has proved lasting because of its simplicity. It is a corner-stone, not a complete building; or, rather, to return to the old figure, it is a root, not a perfect vine.
