Sec. 4. It shall be the duty of the Commissioners Court at the time other taxes are levied in the county to levy a tax under this law of Twenty-five (25) Cents on the one hundred dollars valuation in said county for that year. Such taxes shall be assessed by the Tax Assessor and collected by the Tax Collector as other taxes are assessed and collected. The money collected from said Twenty-five (25) Cents tax shall be distributed to the various school districts in such county as follows:

All districts in the county shall receive the same amount of money for each scholastic, for the maintenance of schools in such district. No part of the moneys realized from said county-wide maintenance tax shall be used to pay any present or future bond issues or interest thereon. The Tax Collector shall, each month, apportion to each district the pro rata part of the taxes collected and dispose of same as hereinafter provided. The valuations fixed by the County Board of Equalization for State and county taxation purposes shall be used in computing said taxes and in levying and collecting the same. The budget officer of each school district in said county as provided by Statute, and the trustees of each of said districts, after receiving the notice of the estimate of the Commissioners Court as herein provided for, and the notice of the State apportionment of public school funds to said district, shall proceed to make and approve the budget for their respective districts as provided by Acts 1931, Forty-second Legislature, Regular Session, page 339, Chapter 206.
