When, at any time hereafter, the aggregate value of all taxable property in any one county be a sum total less than two and one-half million dollars, upon petition of one-fourth or more of the qualified electors of such county, as shown by the last general election, signed, verified, and filed with the county commissioners thereof, not less than sixty days before the date of any general election, such county commissioners shall submit, upon the ballot at such next ensuing general election, to the qualified electors of the county, the question: “Shall the county be an unorganized county?” “Yes” or “No.” If a majority of the votes cast on this question at such election shall be in the affirmative, such county shall thereafter be unorganized and be attached to and be a part of the adjoining county having the lowest valuation of taxable property, and shall so remain as a district in such county until such time as the qualified electors of such unorganized county shall, by similar petition and vote, declare in favor of separate organized county existence: Provided, however, That at all times during such unorganized existence, such county shall have four terms of county court at the county seat therein each year, and the judge of the county court shall appoint a clerk of the county court of said district, from among the qualified electors thereof, who shall keep and maintain his office at such county seat: Provided, further, That while so unorganized, such county shall, in all respects, be part and parcel of the county with which it is united.
