When a common school is taught in connection with an agricultural high school, the election of teachers for the common school department shall be made by the common school trustees in the same manner as is required of other common school trustees.
The trustees may, where in their judgment it would be beneficial to the school, pay the traveling expenses, hotel bills, and other necessary expenses of the executive head of the school in promoting the school's general welfare, provided that such traveling expenses, hotel bills, and other necessary expenses shall not exceed Nine Hundred Dollars ($900.00) annually.
Each member of the board of trustees, the county superintendent excepted, shall receive his actual expenses while on duty, provided that said expenses do not exceed Twelve Dollars and Fifty Cents ($12.50) per day, to be paid out of the county agricultural high school fund on receipt of an itemized statement issued to the county superintendent.
The board of trustees of a school established or maintained by the joint action of two or more counties, shall have all the power and discharge all the duties appertaining to boards of trustees of schools where only one county is interested.
