When an issue of fact to be tried by a jury is brought to trial, the district judge or jury commissioner in the presence of two witnesses must openly draw out of the trial juror box as many of the ballots with the names of jurors thereon, one after another, as are sufficient to form a jury for the cause to be tried. Upon stipulation of counsel, the court may order such jurors to be seated in the order drawn.
