Whenever one hundred or more electors of any county having a hospital tax in force shall file a petition with the county judge asking that such tax be raised, reduced or abolished, the question shall be submitted to the qualified electors at a general election. Such petition must be filed at least thirty days prior to the election at which it will be submitted to the voters. The ballots shall follow, as far as practicable, the form set out in Section 1 hereof, and the result shall be certified and proclaimed as provided in Section 2 hereof and shall be conclusive in like manner. The tax shall be lowered, raised or abolished as the case may be, according to the majority of qualified electors voting on the question at such election, provided, however, that it shall not be raised to more than one mill on the dollar. If lowered or raised the revised tax shall thereafter be continually levied and collected and the proceeds used in the manner and for the purposes provided in Section 2 hereof.
