The plaintiff must, within 30 days after final judgment, pay the sum of money assessed. If the plaintiff is a railroad company, it shall also execute to the defendant a bond, with sureties to be determined and approved by the court or judge, conditioned that the plaintiff shall build proper fences through any enclosed field before commencing actual construction. In an action on the bond all damages sustained and the cost of the construction of such fences and cattle guards, with a reasonable attorney fee, to be fixed by the court, may be recovered.
