Whenever in an action brought under the provisions of this chapter an issue is formed whereby it appears that the attendance of a jury will be necessary to assess the damages in such action, the plaintiff therein may apply to the judge of the district court where the same is pending for an order requiring a jury to be summoned to assess the damages in such action. Thereupon the judge shall issue an order to the clerk of said court requiring a jury to be summoned, and in such order shall specify the number of jurors to be drawn, the place where they are to appear, and the time when they shall come, which shall be not less than eight days nor more than thirty days from the date thereof.
