A little knowledge of history, coupled with even a smaller amount of historical imagination, will enable us to picture the sensation which Carson and his story caused at the Capital. Polk, Webster, Clay, and the other statesmen who met him were impressed with his quiet dignity, his candor and the absence of swagger in his demeanor. No longer could Congress listen with the old-time seriousness to the tales of the alleged Sahara barrenness of the western plains, for Frémont's story, just published in its first instalment, told of streams, of occasional tracts of timber, and of vast herds of buffalo. And here in Washington was the man who had piloted Frémont on his expeditions. From this time dates the decline of the myth of the Great American Desert, which the reports of Pike and of Long and Irving's chronicle of the overland march of the Astorians projected across the map of the second quarter of the nineteenth century from the western border of Missouri to the Sierra Nevada. With their imperialist notions, Senators Benton, Cass, and Douglas saw in Carson the advance courier of manifest destiny.
With the modesty which was one of his characteristics, Carson declined to accept himself at the appraisement which Washington gave him. As he viewed them, his achievements were merely part of his day's work, for the performance of which he deserved no special credit. Accordingly he left the Capital gladly with the despatches which Polk gave him for the military commander in California, and then, after another journey back to Washington, he returned, in 1848, to Taos, and resumed the life of a ranchman, which had been interrupted six years earlier.
Once more now, in Carson's case, we see the initiative, the versatility, and the resourcefulness which the frontier conditions of the older day demanded. In their widely different fields, Crockett, Sam Houston, and Lincoln disclosed these qualities. Appointed in 1853 Indian agent for the district of New Mexico and vicinity by President Pierce,--a post which he held till his death, except for the interlude of the Civil War, in which he rose to the rank of a brigadier-general,--he entered a sphere in which he gained a new distinction. The most formidable Indian-fighter of his age, he was equally successful as a counselor and conciliator of Indians. His administration stands guiltless of any complicity in the "century of dishonor."
