Alabama Constitution of 1901, Art. XIV, § 260

The income arising from the sixteenth section trust fund, the surplus revenue fund, until it is called for by the United States government, and the funds enumerated in sections 257 and 258 of this Constitution, together with a special annual tax of thirty cents on each one hundred dollars of taxable property in this state, which the legislature shall levy, shall be applied to the support and furtherance of education, and it shall be the duty of the legislature to increase the educational fund from time to time as the necessity therefor and the condition of the treasury and the resources of the state may justify;  provided, that nothing herein contained shall be so construed as to authorize the legislature to levy in any one year a greater rate of state taxation for all purposes, including schools, than sixty-five cents on each one hundred dollars' worth of taxable property;  and provided further, that nothing herein contained shall prevent the legislature from first providing for the payment of the bonded indebtedness of the state and interest thereon out of all the revenue of the state.

Except as they may be specifically set aside in trust funds or otherwise applied to the payment of indebtedness, all proceeds of income or other taxes levied by the state, and of all special ad valorem or other taxes levied by counties and other municipalities, or school districts, pursuant to the Constitution as heretofore amended, for public school purposes, shall be applied to the support and furtherance of education pursuant to section 256 of the Constitution, as amended.
