§ 314. For what purpose private road may be used. Every such private road, when so laid out, shall be for the use of such applicant, his heirs and assigns; but not to be converted to any other use or purpose than that of a road; nor shall the occupant or owner of the land through which said road shall be laid out be permitted to use the same as a road, unless he shall have signified such intention to the jury who assessed the damages for laying out such road, and before such damages were assessed.
