Refund to collector on proof of deficiencies in collections

When the collector has duly accounted with the commissioner or county mayor for the full amount of the year's revenue, and paid it into the treasury, without obtaining a credit for insolvencies or deficiencies of payment, and the collector afterwards, in the manner and within the time prescribed by law, procures the proper evidence to authorize the commissioner or county mayor to credit the collector with the evidence, such officers shall respectively issue to the collector a warrant for the amount of such insolvencies or deficiencies of payment.
