Pennsylvania Statutes Title 71 P.S. State Government § 1816. To what townships islands belong

And if any difficulty arise concerning the townships, to which the said islands or other dry land within the said river belongs, the same shall be adjusted by the justices of the peace  1 of the proper county at their general quarter sessions, and they shall determine the same, so as that no island in the said river be divided between two townships or precincts, but the same shall be annexed to the township which would, by dividing the same, be entitled to the major part of such island.
