"Unlike too many of those who in modern times invoke their authority, they had a choice between the two. They preferred the system of free labor, and they determined to organize the Government, and so to direct its activity, that that system should surely and certainly prevail. For this purpose, and no other, they based the whole structure of government broadly on the principle that all men are created equal, and therefore free--little dreaming that within the short period of one hundred years, their descendants would bear to be told by any orator, however popular, that the utterance of that principle was merely a rhetorical rhapsody; or by any judge, however venerated, that it was attended by mental reservations, which render it hypocritical and false. By the ordinance of 1787, they dedicated all the national domain not yet polluted by slavery to free labor immediately, thenceforth and forever, while by the new Constitution and laws they invited foreign free labor from all lands under the sun, and interdicted the importation of African slave labor, at all times, in all places, and under all circumstances whatsoever. It is true that they necessarily and wisely modified this policy of freedom by leaving it to the several States, affected as they were by differing circumstances, to abolish slavery in their own way, and at their own pleasure, instead of confiding that duty to Congress, and that they secured to the slave States, while yet retaining the system of slavery, a three-fifths representation of slaves in the Federal Government, until they should find themselves able to relinquish it with safety. But the very nature of these modifications fortifies my position that the fathers knew that the two systems could not endure within the Union, and expected that within a short period slavery would disappear forever. Moreover, in order that these modifications might not altogether defeat their grand design of a republic maintaining universal equality, they provided that two-thirds of the States might amend the Constitution. "_It remains to say on this point only one word, to guard against misapprehension. If these States are to again become universally slaveholding, I do not pretend to say with what violations of the Constitution that end shall be accomplished. On the other hand, while I do confidently believe and hope that my country will yet become a land of universal freedom, I do not expect that it will be made so otherwise than through the action of the several States coöperating with the Federal Government, and all acting in strict conformity with their respective Constitutions_." In a speech in the Senate, last spring, March 2, 1859, Mr. Seward said--he was speaking of the "Expenses and Revenues"--
