"Our Federal system is admirably adapted to the whole continent; and while I would not violate the laws of national or treaty stipulations, or in any manner tarnish the national honor, I would exert all legal and honorable means to drive Great Britain and the last vestige of royal authority from the continent of North America, and extend the limits of the republic from ocean to ocean." Elected to the Senate at the age of thirty-four, Douglas took his seat in that august body in December, 1847. On the same day Abraham Lincoln took the oath of office as a member from Illinois in the House of Representatives. The Senate was presided over by the able and accomplished Vice-President, George M. Dallas. Seldom has there been a more imposing list of great names than that which now included the young Senator from Illinois. Conspicuous among the Senators of the thirty States represented, were Dix of New York, Dayton of New Jersey, Hale of New Hampshire, Clayton of Delaware, Reverdy Johnson of Maryland, Mason of Virginia, King of Alabama, Davis of Mississippi, Bell of Tennessee, Corwin of Ohio, Crittenden of Kentucky, Breese of Illinois, Benton of Missouri, Houston of Texas, Calhoun of South Carolina, and Webster of Massachusetts. It need hardly be said that the debates of that and the immediately succeeding Congress have possibly never been surpassed in ability and eloquence by any deliberative assembly. The one vital and portentous question--in some one of its many phases--was that of human slavery. This institution--until its final extinction amid the flames of war--cast its ominous shadow over our nation's pathway from the beginning. From the establishment of the Government under the Federal Constitution to the period mentioned, it had been the constant subject of compromise and concession. Henry Clay was first known as "the great pacificator" by his tireless efforts in the exciting struggle of 1820, over the admission of Missouri--with its Constitution recognizing slavery--into the Federal Union. Bowed with the weight of years, the Kentucky statesman, from the retirement he had sought, in recognition of the general desire of his countrymen, again returned to the theatre of his early struggles and triumphs. The fires of ambition had burned low by age and bereavement, but with earnest longing that he might again pour oil upon the troubled waters, he presented to the Senate, as terms of final peaceable adjustment of the slavery question, the once famous compromise measures of 1850. The sectional agitation then at its height was measurably the result of the proposed disposition of territory acquired by the then recent treaty with Mexico. The advocates and opponents of slavery extension were at once in bitter antagonism, and the intensity of feeling such as the country had rarely known.
