The board of trustees shall also elect a treasurer for the college who shall not be a trustee. The treasurer shall receive, hold and pay out all moneys belonging to the college, or that may be paid in for the necessary expenses of any student in the college, or for the use and benefit of any such student. The treasurer shall hold office for the term and receive the compensation fixed for such office by the board of trustees. Before entering upon his duties, the treasurer must give bond in such penalty as the trustees prescribe, payable to the college, conditioned that he will faithfully receive, safely keep and lawfully pay out, and promptly, fully and fairly account for all money or choses in action which may come to him by virtue of his office, and the trustees may require a new bond, or an additional bond, whenever, in their opinion, the interests of the college require it.
