Each officer required by law or ordinance to give bond shall do so before entering upon the duties of the office, except as otherwise provided in this chapter. In its discretion, council at any time may require each officer to give a new or additional bond. Except that of the clerk, each bond upon its approval shall be delivered to the clerk, who shall immediately record it in a record provided for that purpose and file and carefully preserve it in his office. The bond of the clerk shall be delivered to the mayor, who shall in like manner record and preserve it.
