When, upon a trial of the issues presented, no sufficient cause is shown for the failure of the principal to appear, the judgment shall be made final against him and his sureties, if any, for the amount in which they are respectively bound; and the same shall be collected by execution as in civil actions. Separate executions shall issue against each party for the amount adjudged against him. The costs shall be equally divided between the sureties, if there be more than one.
