In assuming responsibilities so vast I fervently invoke the aid of that Almighty Ruler of the Universe in whose hands are the destinies of nations and of men to guard this Heaven-favored land against the mischiefs which without His guidance might arise from an unwise public policy.  With a firm reliance upon the wisdom of Omnipotence to sustain and direct me in the path of duty which I am appointed to pursue, I stand in the presence of this assembled multitude of my countrymen to take upon myself the solemn obligation “to the best of my ability to preserve, protect, and defend the Constitution of the United States.”

A concise enumeration of the principles which will guide me in the administrative policy of the Government is not only in accordance with the examples set me by all my predecessors, but is eminently befitting the occasion.

The Constitution itself, plainly written as it is, the safeguard of our federative compact, the offspring of concession and compromise, binding together in the bonds of peace and union this great and increasing family of free and independent States, will be the chart by which I shall be directed.

It will be my first care to administer the Government in the true spirit of that instrument, and to assume no powers not expressly granted or clearly implied in its terms.  The Government of the United States is one of delegated and limited powers, and it is by a strict adherence to the clearly granted powers and by abstaining from the exercise of doubtful or unauthorized implied powers that we have the only sure guaranty against the recurrence of those unfortunate collisions between the Federal and State authorities which have occasionally so much disturbed the harmony of our system and even threatened the perpetuity of our glorious Union.

“To the States, respectively, or to the people” have been reserved “the powers not delegated to the United States by the Constitution nor prohibited by it to the States.”  Each State is a complete sovereignty within the sphere of its reserved powers.  The Government of the Union, acting within the sphere of its delegated authority, is also a complete sovereignty.  While the General Government should abstain from the exercise of authority not clearly delegated to it, the States should be equally careful that in the maintenance of their rights they do not overstep the limits of powers reserved to them.  One of the most distinguished of my predecessors attached deserved importance to “the support of the State governments in all their rights, as the most competent administration for our domestic concerns and the surest bulwark against antirepublican tendencies,” and to the “preservation of the General Government in its whole constitutional vigor, as the sheet anchor of our peace at home and safety abroad.”
