(a) The account of the clerk of the county court against the county collector for the licenses provided for in this act shall be so kept as to show by denominations and numbers exactly what licenses issued to the county collector by the clerk are in the county collector's hands at any time. Upon the final settlement of each county collector, the clerk of the county court shall require the return by the county collector of all licenses issued to the county collector and not issued by the county collector.
(b) The county collector shall receive credit for all of such licenses as he or she shall return to the clerk without having issued them.
(c) For all licenses the county collector shall not thus account for, the county collector shall be held liable upon his or her official bond as county collector for so much money as the amount of the licenses, and the clerk shall certify the settlement to the Auditor of State.
