When the administration of any estate is committed to the sheriff, the judge of probate, at such time or at any time thereafter, while the administration is in the hands of such officer, may require of him an additional bond if, in his opinion, the official bond of such officer is not sufficient security for the protection of the estate; and if he fails to give such additional bond for 10 days after notice that the same is required, he vacates his office, and the judge of probate must certify the vacancy to the appointing power.
