In counties which have secured property and completed arrangements for the working of their convicts, the board of county commissioners, whenever practicable, shall cause to be worked as provided in sections 5147.01 to 5147.26, inclusive, of the Revised Code, all convicts sentenced to imprisonment at hard labor, and also all male convicts, physically capable of performing hard labor, confined in the county jail or workhouse for failure to pay a fine in criminal prosecution, or who plead insolvency or inability to pay such fine. A person confined for failure to pay a fine shall be released when the fine has been discharged by his labor at the rates to be fixed by such board.
