In case any number of the persons interested in the land to be inclosed shall desire to have their allotments thrown together, and distinguished by metes and bounds, but not fenced from each other, and of such their desire shall give notice in writing to the valuer acting in the inclosure, such valuer shall set out the several allotments of such persons so giving notice as aforesaid by metes and bounds, but in one parcel of land, and without requiring them to make any sub-division fences or other fences, save such ring or outer fences as may be necessary, or as the valuer may direct to be made, for dividing the said parcel of land from the residue of the land so to be inclosed.
