The Fifteenth Amendment was not explicit. Instead of asserting the right of the negro to vote, it said, by negation, that the right should not be denied on account of "race, color, or previous condition of servitude." The three qualities of race, color, and servitude separated the races, but the South learned that they were separated by other qualities that were not proscribed by the amendment as a basis for the franchise. The negro was generally poor, and any qualification based on property would exclude him. He was shiftless, and often vagrant, and hence could be touched by poll-tax and residence requirements. He was illiterate, and was unable to meet an educational test. Tired of using force or fraud, the South began in 1890 a system of legal evasion of the Fifteenth Amendment. The State of Mississippi, in a new constitution framed in 1890, defined the franchise in terms that bore heavily upon the negro. In the debates of its convention members talked frankly and freely of their intention to disqualify the race; the clause bore no mention of discrimination. It permitted persons to vote who, being male citizens over twenty-one, and having reasonable residence qualifications, had paid a poll or other tax for two years preceding the election, and could read, or understand and interpret when read to them, any section of the constitution of the State. Under this clause, between the cumulative tax and the large discretionary powers vested in the officers of enrollment, the negro electorate was reduced until it was negligible in Mississippi; and it was a subject of admiration for other Southern States, which proceeded to imitate it. All of the cotton States but Florida and Texas, and most of the old slave States, revised their electoral clauses in the next twenty years. Arkansas, in 1893, based the franchise on a one-year poll-tax. South Carolina, in 1895, used residence, enrollment, and poll-tax, while the convention called to disfranchise the negro passed resolutions of sympathy for Cuban independence. Delaware, in 1897, established an educational test. Louisiana, in 1898, established education and a poll-tax; North Carolina, in 1900, did the same. Alabama, in 1901, made use of residence, registry, and poll-tax. Virginia based the suffrage on property, literacy, or poll-tax in 1902. Georgia did the same in 1908, and the new State of Oklahoma followed the Southern custom in 1910.
