Dennis:
Because South Carolina was created before the system of surveying created by the Northwest Ordinance, we did not have such a system. The schools, under the S. C. Constitution of 1868, were supported by a 3 mill tax on the assessed value of property, real and personal, levied in each school district. After the end of Reconstruction, that meant that each district was supporting a dual school system, with very little taxable income. Some districts levied additional taxes to support the schools, but the legal rate, I understand, was the three mill tax, plus the dog tax. It wasn't much.
