Where service has been made by publication, and no answer has been filed nor appearance entered within the prescribed time, the court shall appoint an attorney to defend the suit in behalf of the defendant, and judgment shall be rendered as in other cases; but, in every such case a statement of the evidence, approved and signed by the judge, shall be filed with the papers of the cause as a part of the record thereof. The court shall allow such attorney a reasonable fee for his services, to be taxed as part of the costs.
