If the assurance fund shall be insufficient at any time to meet the amount called for by any such certificate, the Treasurer shall pay the same from any funds in the treasury not otherwise appropriated; and in such case any amount thereafter received by the Treasurer on account of the assurance fund shall be transferred to the general funds of the treasury until the amount advanced shall have been paid. (1913, c. 90, s. 36; C.S., s. 2425.)
