Each county agricultural agent may be the secretary to the board of commissioners of each district within his county. The commissioners may also utilize in other respects the services of the agricultural agents and the facilities of the county agricultural agent's officers insofar as practicable and feasible and may employ such additional employees and agents, permanent and temporary, as they may require and shall determine their qualifications, duties and compensation. The commissioners may delegate to their chairman or to one or more agents, or employees such powers and duties as they may deem proper. The commissioners may call upon the Attorney General of the State for such legal services as they may require or may employ their own counsel and legal staff.
