When a person has made a fence or other improvement on an enclosure, which is found to be on land of another, such person may enter upon the land of the other and remove the fence or other improvement and material, upon the first paying, or offering to pay, the other party for any damage to the soil which may be occasioned thereby, and the value of any timber used in said improvement taken from the land of such other party, if any; and if the parties cannot agree as to the damages, the fence viewers may determine them as in other cases; such removal shall be made as soon as practicable, but not so as to expose the crops of the other party.
