11. When, in a township, the front of the first range happens to be a line on which no division posts have been planted, or is formed by the shore of a lake or water course on which there is no such post, the front line referred to is the range line next above the first, and the side lines of the lots shall be traced from the posts planted thereon, or from those which have been lawfully substituted for them on either side, in opposite directions for the first and the second ranges, the front being common to both.
