Education of the Negro 

pub One.info present you this new edition. At the close of the war for the Union about five millions of negroes were added to the citizenship of the United States. By the census of 1890 this number had become over seven and a half millions. I use the word negro because the descriptive term black or colored is not determinative. There are many varieties of negroes among the African tribes, but all of them agree in certain physiological if not psychological characteristics, which separate them from all other races of mankind; whereas there are many races, black or colored, like the Abyssinian, which have no other negro traits.
