At the close of each month, or more frequently if necessary, there shall be filed with the county clerk an itemized and detailed reconciliation and statement of payments made out of any petty cash fund authorized under this act. Such detailed statement shall be supported by itemized receipts for each expenditure. Upon receiving any such statement, the county clerk shall draw his warrant against the fund from which payments would have been paid if the same had not been paid out of such petty cash fund, to restore such petty cash fund to its original amount.
