In the Southwest are over eighteen hundred miles of boundary line between ourselves and the people of Mexico. I know that I am expressing for my colleagues of the Ku Klux Klan who dwell along that eighteen hundred miles of boundary line their inmost thought, when I say that they wish only peace and fellowship and mutual aid and generosity to mark all our relations with the simple and kindly people of Mexico. But we are here marshalling the facts--the staggering facts which the American people must know and ponder well to-day. Nearly half a million Mexicans, speaking various dialects of the Spanish and Indian languages, have recently come across our Southwestern boundary line. Surely it is not with any ill will in our hearts that we say with all the power we have that these thousands can not share our American democracy with us in this generation. In Mexico these people can be ruled in such a way and take such measures of progress as may befit them. Granted time and they may evolve a successful democracy all their own. But in this generation they will make democracy impossible wherever large numbers of them settle among us. If immigration continues through the next generation THEY WILL FOREVER ENCROACH UPON AND OCCUPY OUR SOUTHWEST. The native-born, white American will either become a small ruling class, or fade from sight altogether. There are factories in Texas with practically none but Mexicans employed. There are sections of the Southwest where, in town and on the countryside, there are many Negroes, Mexicans and Japanese, few Americans. Finally, we come to the South. Leaving the burden of this argument to future chapters, we can here take but a rapid glance at the inexorable problem of the Southland. May Providence give to us men and women of the South the power we need to place our problem before our fellow citizens in other sections in such a way as to win their minds and hearts by the goodness of our cause. If I but could, I would move my hand along that ancient and deadly line which separates us from our country-men and wipe it out forever. Our problem of the Negro, men and women of the North, is your problem. If we fail, you fail. We plead with you to join with us in freeing all our minds from bigotry, all our hearts from unworthy passions, and all our thoughts from sectional misunderstanding.
