Noah Haynes Swayne,
Conway v. Taylor's Executor — Opinion of the Court
“ Rights of commerce give no authority to their possessor to invade the rights of property. He cannot use a bridge, a canal, or a railroad without paying the fixed rate of compensation. He cannot use a warehouse or vehicle of transportation belonging to another without the owner's consent. No more can he invade the ferry franchise of another without authority from the holder. The vitality of such a franchise lies in its exclusiveness. The moment the right becomes common, the franchise ceases to exist. ”
