Mr. John Quincy Adams had followed Douglas with the keenest interest, for with all the vigor which his declining strength permitted, he had denounced the war as an aggression upon a weaker neighbor. He had repeatedly interrupted Douglas, so that the latter almost insensibly addressed his remarks to him. They presented a striking contrast: the feeble, old man and the ardent, young Westerner. When Douglas alluded to the statement of Mr. Adams in 1819, that "our title to the Rio del Norte is as clear as to the island of New Orleans," the old man replied testily, "I never said that our title was good to the Rio del Norte from its mouth to its source." But the gentleman surely did claim the Rio del Norte in general terms as the boundary under the Louisiana treaty, persisted Douglas. "I have the official evidence over his own signature.... It is his celebrated dispatch to Don Onis, the Spanish minister." "I wrote that dispatch as Secretary of State," responded Mr. Adams, somewhat disconcerted by evidence from his own pen, "and endeavored to make out the best case I could for my own country, as it was my duty; but I utterly deny that I claimed the Rio del Norte in its whole extent. I only claimed it as the line a short distance up, and then took a line northward, some distance from the river." "I have heard of this line to which the gentleman refers," replied Douglas. "It followed a river near the gorge of the mountains, certainly more than a hundred miles above Matamoras. Consequently, taking the gentleman on his own claim, the position occupied by General Taylor opposite Matamoras, and every inch of the ground upon which an American soldier has planted his foot, were clearly within our own territory as claimed by him in 1819."[228] It seemed to an eyewitness of this encounter that the veteran statesman was decidedly worsted. "The House was divided between admiration for the new actor on the great stage of national affairs and reverence for the retiring chief," wrote a friend in after years, with more loyalty than accuracy.[229] The Whig side of the chamber was certainly in no mood to waste admiration on any Democrat who defended "Polk the Mendacious."
