by John Marshall Harlan, Parkersburg Ohio River Transp Company v…
“ Is not the substantial privilege of landing passengers and freight necessarily involved in the right of entering the port? If so, it would seem that the right to land a boat at a public wharf on a navigable water of the United States is as fully protected by the Constitution and the existing laws of the United States as that of entering the port. A charge, tax, or duty imposed upon the exercise of the right to land is consequently, for every practical purpose, as much a duty of tonnage as a charge, tax, or duty upon the privilege of entering the port. ”
