One of Benton's earliest public utterances was in regard to a matter which precisely illustrates this feeling. It was while Missouri was still a territory, and when Benton, then a prominent member of the St. Louis bar, had by his force, capacity, and power as a public speaker already become well known among his future constituents. The treaty with Spain, by which we secured Florida, was then before the Senate, which body had to consider it several times, owing to the dull irresolution and sloth of the Spanish government in ratifying it. The bounds it gave us were far too narrow to suit the more fiery Western spirits, and these cheered Benton to the echo when he attacked it in public with fierce vehemence. "The magnificent valley of the Mississippi is ours, with all its fountains, springs, and floods; and woe to the statesman who shall undertake to surrender one drop of its water, one inch of its soil to any foreign power." So he said, his words ringing with the boastful confidence so well liked by the masterful men of the West, strong in their youth, and proudly conscious of their strength. The treaty was ratified in the Senate, nevertheless, all the old Southern States favoring it, and the only votes at any stage recorded against it being of four Western senators, coming respectively from Ohio, Kentucky, Tennessee, and Louisiana. So that in 1818, at any rate, the desire for territorial aggrandizement at the expense of Maine or Mexico was common to the West as a whole, both to the free and the slave states, and was not exclusively favored by the Southerners. The only effect of Benton's speech was to give rise to the idea that he was hostile to the Southern and Democratic administration at Washington, and against this feeling he had to contend in the course of his successful candidacy for the United States senatorship the following year, when Missouri was claiming admittance to the Union.
