After the jury has been sworn, it shall, from an examination of the premises, and upon such legal evidence as either party may produce, assess:
(1) The damages, if any, which may have been done the land by cultivation and unnecessary waste of timber after the suit was instituted;
(2) The rents and profits which have accrued after final judgment or decree of eviction; and (3) The value of the improvements upon the land from which the occupant is to be evicted, to be estimated as of the time the jury is impaneled. The inquest and verdict shall be signed by the jurors.
