If the sale shall not be completed on the day designated in the notice for the holding of such sale, it shall be continued from day to day between the same hours until disposition shall have been made of all the land. The payment for any tax lien purchased at a sale shall be made by check or money order payable to the sheriff of the county and delivered before the close of business on the day of the sale.

(b) Each sheriff is immune from liability if a loss or claim results from the sale of a tax lien conducted pursuant to the provisions of this article or from any subsequent conveyance of the property to which the lien attaches: Provided, That where a sheriff fails or refuses to sell said tax lien pursuant to the provisions of this article for reasons other than those provided by section seven of this article, the sheriff may be compelled by mandamus to sell the same upon the petition of the auditor or any taxpayer of the county in a court of competent jurisdiction.
