25-1634. Petit jury; extra jurors to complete panel; talesmen.
If for any reason it appears to the judge that the panel of petit jurors will not be adequate at the opening of the court, or at any time during the term, the jury commissioner shall, when ordered by the judge or judges of the court draw, in the same manner and presence as the first drawing, such number of jurors as the judge or judges shall direct to fill such panel or as extra jurors, and those drawn shall be notified and summoned in the same manner as the others or as the court may direct. This shall also apply to the selection of talesmen for particular causes after the regular panel is exhausted.
