When a claim shall have been once audited and reported to the county clerk by the auditor, he shall not be required, nor is he authorized to re-examine and reaudit the same claim, nor any part thereof, unless the same shall be certified to him by the county clerk within six months of the date of its being first audited. And it shall be the further duty of said auditor to examine all accounts and settlements to be made by the county treasurer with the board of county commissioners, and make such preparation of the accounts of such treasurer before the settlement, as shall be ordered by the chairman of the board of county commissioners.
