Expenses of witnesses are paid into court by the applicant for summons, and summons to attend will subsequently be issued to witness named. Summons must specify time and place of attendance. Where expenses have been underestimated the court may direct the applicant to estimate the sum. Where any witness fails to accept service, or having accepted service fails to appear and it seems to the court that such non-acceptance or nonattendance is deliberate, he may be arrested or his can be property attached as a penalty.
