To the westward and north-westward of Missouri and Iowa lay a vast territory which in 1854 was not only unsettled but had no form of civil government whatever. It stretched from the north line of Arkansas to the border of British America,--twelve and a half degrees of latitude,--and westward over great plains and across mountain ranges till it reached the confines of Utah and Oregon. It was the unorganized remainder of the territory of Louisiana, acquired from France in 1803, and in extent was ten times as large as the combined area of New York and Pennsylvania. By the Missouri Compromise every square mile of this domain had been honorably devoted to freedom. At the period named Indian tribes roamed at will throughout its whole extent and lighted their camp-fires on the very borders of Missouri and Iowa. Herds of buffalo grazed undisturbed on lands which to-day constitute the sites of large cities. Fort Leavenworth was a far-western outpost, Council Bluffs was on the frontier of civilization, and Omaha had not been named. Adventurous merchants passed over the plains to the South-West with long caravans, engaged in the Santa-Fe trade, and towards the North- West, hunters, trappers, and a few hardy emigrants penetrated the "Platte country," and through mountain passes pointed out by the trail of the Indian and the buffalo had in many instances safely crossed to Oregon. The tide of emigration which had filled Iowa and Wisconsin, and which by the gold excitement of California had for a time been drawn to the Pacific slope, now set again more strongly then ever to the Mississippi valley, demanding and needing new lands for settlement and cultivation. To answer this requirement a movement was made during the closing weeks of Mr. Fillmore's administration to establish the territory of Nebraska. A bill to that effect was passed by a two-thirds vote in the House. The slight opposition that was made came from the South, but its significance was not perceived. When the bill reached the Senate Mr. Douglas, as chairman of the committee on territories, promptly reported it, and made an apparently sincere effort to pass it. He did not succeed. Every senator from the slave-holding States, except those from Missouri,--which was locally interested in having the territory organized,--voted against it;--and the measure, antagonizing other business in which Northern senators were more immediately interested, was laid upon the table two days before President Pierce was inaugurated. The bill had fully recognized the binding force of the Missouri Compromise, and if it had passed, there could have been no pretense for the introduction of slavery in the territory of Nebraska.
