America has to-day no problem more perplexing and disquieting than that of the proper and permanent rela tions between the white and the colored races. Although it concerns most vitally the twenty millions of Caucasians and the eight millions of Negroes in eleven States of the South, still it is a national problem, because whatever affects one part of our national organism concerns the whole of it. Although this question has been considered from almost every conceivable standpoint, few have turned to the laws of the States and of the Nation to see how they bear upon it. It was with the hope of gaining new light on the subject from this source that I undertook the present investigation.
