Every person summoned to appear as a juror who has not been excused, and who fails to appear and attend until duly discharged, shall be subject to a fine of not more than fifty dollars ($50.00), to be imposed by the court, unless he renders an excuse deemed sufficient. The forfeiture so imposed if not paid forthwith shall be entered as a judgment against the defaulting juror, and the clerk of superior court shall issue an execution against his estate.
