Mississippi Code Title 19. Counties and County Officers § 19-5-71

The boards of supervisors of the several counties may, in their discretion, appropriate money from the general funds of the county for the purpose of buying lands, personal property, or equipment of whatever nature and kind, for experiment stations, and may appropriate money from said county funds to aid in the support and maintenance of such experiment stations, whether the same be located within or without the county. When any board of supervisors desire to appropriate funds as herein provided, they shall first publish notice of said proposed expenditure setting forth the amount thereof and the purposes for which said funds are to be used, and upon petition of ten per cent of the qualified electors in said county, the board shall submit to the qualified electors at a special election to be held in said county the question of whether or not said expenditure shall be made, and in the event the majority of the qualified electors shall vote against such expenditure, then the same shall not be made, and such proposal shall not again be made within twelve months from said election.
