The affidavit shall be filed in the office of the clerk of the circuit court for the county, and a copy thereof kept conspicuously at the place of weighing.
4. Miners employed in any coal mine have the power, if they desire, of employing at their own expense, a check-weighmaster, who shall have the right to be present and observe the weighing of coal by the weighmaster, to examine and test the scales, to inspect the records made by the weighmaster; and to be subject to the same qualifications, oath and penalties as the weighmaster.
