If it appears that there is a shortage in the supplies of any institution, the supervising department having control of such institution shall appoint a committee to investigate the cause thereof. If it appears that the shortage resulted from unavoidable loss, without the negligence of the officer designated to have charge of the supplies, such officer must be credited therewith, otherwise the officer must be charged with the amount thereof and must be required to pay the same into the state treasury within sixty days after the determination of the loss. If default is made in such payment, the officer shall forfeit the office and suit must be instituted upon the officer’s official bond to recover the same.
