No great question involving the existence of slavery was brought before the attention of Congress during Van Buren's term of office; nor was the matter mooted except in the eternal wrangles over receiving the abolitionist petitions. Benton kept silent in these discussions, although voting to receive the petitions. As he grew older he continually grew wiser, and better able to do good legislative work on all subjects; but he was not yet able to realize that the slavery question was one which could not be kept down, and which was bound to force itself into the sphere of national politics. He still insisted that it was only dragged before Congress by a few fanatics at the North, and that in the South it was made the instrument by which designing and unscrupulous men wished to break up the federal republic. His devotion to the Union, ever with him the chief and overmastering thought, made him regard with horror and aversion any man, at the North or at the South, who brought forward a question so fraught with peril to its continuance. He kept trying to delude himself into the belief that the discussion and the danger would alike gradually die away, and the former state of peaceful harmony between the sections, and freedom from disunion excitement, would return. But the time for such an ending already lay in the past; thereafter the outlook was to grow steadily darker year by year. Slavery lowered like a thunder-storm on the horizon; and though sometimes it might seem for a moment to break away, yet in reality it had reached that stage when, until the final all-engulfing outburst took place, the clouds were bound for evermore to return after the rain. CHAPTER XI. THE PRESIDENT WITHOUT A PARTY. The Whigs in 1840 completely overthrew the Democrats, and for the first time elected a president and held the majority in both houses of Congress. Yet, as it turned out, all that they really accomplished was to elect a president without a party, for Harrison died when he had hardly more than sat in the presidential chair, and was succeeded by the vice-president, Tyler of Virginia.
