When partition of more than one (1) tract is demanded, the commissioners shall set off to each plaintiff or party in interest his proper proportion in each of the several tracts unless the several tracts are owned by the same proprietors in the same proportion in each tract, in which case the whole share of any proprietor in all the several tracts may be set off to the proprietor according to the best discretion of the commissioners.
