This upper class contains only persons of exceptional blood, talent, or some other rare fortune. The higher education, and the education which is now best of all for the negro--industrial education--is for this little circle only. Hampton and Tuskegee do not open to all comers. Mr. Tillinghast convincingly proves that those who have got really good training at the two institutions just named are far above the average negro in physical stamina, education, and other important particulars.[184] The graduates go forth, not to benefit their brothers in the lower class, but to win for themselves surer and higher standing in the upper class. Some of the resources which this urban section of the upper class have enjoyed for a while they are losing, as I shall tell when I hereinafter summarize the details of white encroachment. But other resources open to them. Such are professions like dentists, eye, ear, and throat surgeons, doctors, barbers, and others who must content themselves with only colored patronage; such the growing retail trade, multiplying boarding-houses, restaurants, and saloons, finding their custom exclusively in the increasing negro town population. The number of negroes who become teachers, lecturers, preachers, authors, etc., steadily augments. Other resources of this upper class can be pointed out, but it needs not here. Although nearly always when the father who has struggled up dies, his property, as we saw to be the case with the negro farmer, goes, and no child succeeds to his occupation, there is perhaps generally compensation for his loss by the accession of some other who has got up out of the lower class by an extraordinarily lucky jump. It is clear that the class is without the wholesome influence of uninterrupted inheritance, from generation to generation, of faculty and character progressively improving. Take this inheritance away from the men and women of any enlightened nation and it would be to lower them very near to the level of barbarism. It is also nearly certain that there will be no further infusion of white blood into this class, by reason of the hostility to inter-mixture which becomes stronger--yea, intenser--every year. The probable consequence will be the dilution of much of the white blood now in the upper class through the lower class to such an extent that it will practically disappear. But some of it, I think, will persist, perhaps increase in degree--preserved by the aversion of many to intermarriage with persons less white than themselves, and occasional intermarriage with white persons in northern States.
