Stephen Johnson Field,
Gloucester Ferry Company v. Commonwealth of Pennsylvania…
“ Necessarily that power alone can prescribe regulations which are to govern the whole country. And it needs no argument to show that the commerce with foreign nations and between the states, which consists in the transportation of persons and property between them, is a subject of national character, and requires uniformity of regulation. Congress alone, therefore, can deal with such transportation; its non-action is a declaration that it shall remain free from burdens imposed by state legislation. ”
