Now, Sumner's superb vitality, that hardy yeoman blood which his ancestors brought from England, stood him in excellent stead. His strong and active brain was based on a body muscular, vigorous, and healthy, incapable of nervous tremor, bearing him with a steady _aplomb_ through much that would be confusing and weakening to men of less physical force. Sumner had not the character of a ready debater; not a light-armed skirmisher was he; he resembled rather one of the mailed warriors of ancient tourney. When he had deliberately put on his armor, all polished and finished down to buckle and shoe-latchet, and engraved with what-not of classic, or Venetian, or Genoese device; when he put down his visor, steadied his lance, took sure aim, and went man and horse against his antagonist, all went down before him, as went down all before the lance of Coeur-de-Lion. Such a charge into the enemy was his first great speech, "Freedom National, Slavery Sectional," which he directed against the Fugitive Slave Law. It was a perfect land-slide of history and argument; an avalanche under which the opposing party were logically buried, and it has been a magazine from which catapults have been taken to beat down their fortresses ever since. If Daniel Webster merited the title of the great expounder of the constitution, Sumner at this crisis merited that of the great defender of the constitution. In this speech we see clearly the principle on which Charles Sumner, while holding the same conscientious ground with Mr. Garrison in regard to the wickedness of slavery, could yet see his way clear to take the oath to support and defend the constitution of the United States. It was because he believed _ex animo_, that that constitution was an agreement made TO PROMOTE AND DEFEND LIBERTY, and though including in itself certain defective compromises, which never ought to have been there, had yet within itself the constitutional power of revoking even those compromises, and coming over entirely on to the ground of liberty.
