As the year 1860 approached, the political struggle became more and more bitter. President Buchanan in redeeming his promise to maintain the Union had gone to lengths which startled and disappointed many of his most devoted supporters. Civil war had broken out in Kansas and Nebraska, with murder and massacre: desperate attempts were made to fasten the hold of the pro-slavery party permanently upon the State, and as desperately were these efforts repelled. A certain John Brown, who requited assassination of free-state men by the assassination of slave-state men,--a very ominous appearance,--began to be heard of; men like Professor Silliman, who, during my stay at Yale had spoken at Union meetings in favor of the new compromise measures, even including the fugitive slave law, now spoke publicly in favor of sending rifles to the free-state men in Kansas; and, most striking symptom of all, Stephen A. Douglas himself, who had led the Democratic party in breaking the Missouri Compromise, now recoiled from the ultra pro-slavery propaganda of President Buchanan. Then, too, came a new incitement to bitterness between North and South. John Brown, the man of Scotch-Covenanter type, who had imbibed his theories of political methods from the Old-Testament annals of Jewish dealings with the heathen, and who had in Kansas solemnly slaughtered in cold blood, as a sort of sacrifice before the Lord, sundry Missouri marauders who had assassinated free-state men, suddenly appeared in Virginia, and there, at Harper's Ferry, with a handful of fanatics subject to his powerful will, raised the standard of revolution against the slave-power. Of course he was easily beaten down, his forces scattered, those dearest to him shot, and he himself hanged. But he was a character of antique mold, and this desperate effort followed by his death, while it exasperated the South, stirred the North to its depths. Like all such efforts, it was really mistaken and unfortunate. It helped to obscure Henry Clay's proposal to extinguish slavery peaceably, and made the solution of the problem by bloodshed more and more certain. And in the execution of John Brown was lost a man who, had he lived until the Civil War, might have rendered enormous services as a partizan leader. Of course, his action aroused much thought among my students, and their ideas came out in their public discussions. It was part of my duty, once or twice a week, to preside over these discussions, and to decide between the views presented. In these decisions on the political questions now arising I became deeply interested, and while I was careful not to give them a partizan character, they were, of course, opposed to the dominance of slavery.
