“The health of the white people requires that the negro cabin be kept clean; and the maintenance of chastity there is necessary for the protection of woman throughout the land. The need of making the black man more intelligent and conscientious has already been so far recognized by the South, that she has remodelled her entire school system for his benefit; and her desire to make him more valuable as a member of the community, cannot long permit him to be lynched or otherwise maltreated. Her memory of the misrule of the carpet-baggers will grow fainter; and she will finally be able to see that even the illiterate voter is not so dangerous a citizen in a republic as the man who has not this reason to interest himself in its welfare. The South may be much slower than we could wish in reaching these conclusions; but no others will be found permanently satisfactory to her; and it is by no means certain that her pace will be quickened by a display of federal bayonets.”
