The election commissioners shall certify to the county judge the result of the vote and if a majority of the qualified electors voting on the question at such election vote in favor of the specified tax then it shall thereafter be continually levied and collected as other general taxes of such county are levied and collected. The result of the election shall be proclaimed by the county judge by publication for one insertion in some newspaper published and having a bona fide circulation in such county. The result so proclaimed shall be conclusive unless attacked in the courts within thirty days and after the election it shall not be competent to attack the result thereof on the ground that any signers of the petition were not qualified electors. The proceeds of any tax so voted shall upon the settlement of the collecting officer be paid by the treasurer of the county to the treasurer of such hospital to be used by such treasurer in the maintenance, operation and support of such institution; provided that any county where there may be more than one hospital qualified to receive the proceeds of such tax, the quorum court at its meeting for the purpose of adopting the county's budget, shall provide for the apportionment of the proceeds of said tax between the institutions so qualified according to their respective needs.
