In case the county board of education of two or more counties shall so decide, two or more counties may unite in establishing a joint agricultural high school, joint agricultural high school-junior college or two schools. The county boards of education of the two or more counties shall meet in joint session to determine the location of the school or schools, and if no place can be agreed upon by a majority of the joint boards for either school, the two places receiving the greatest number of votes shall be certified by the boards to the state board of education, which board shall select one of them as a site for the school.
In case any county not contributing to the support of an agricultural high school or agricultural high school-junior college desires to co-operate in the maintenance of such a school or schools already established by some other county or counties, and receive therefrom the full privileges and benefits of such an institution, such desire shall be made a matter of record on the minutes of the county board of education of the said county by a majority vote of said board. After such action by the county board of education, the board of supervisors of said county may with the consent of the trustees of the school or schools make a levy for the support of said agricultural high school or agricultural high school-junior college. After such levy has been made, the county shall, so far as the law is concerned, have all the privileges, rights, and duties concerning the operation of said school in every respect as the county or counties originally establishing said agricultural high school or agricultural high school-junior college.
