The waters of the Bay of New-York and of the Hudson river flow entirely within the States of New-York and New-Jersey. One of the vested rights of an independent state, is that known as 'eminent domain,' or supreme ownership, implying control. Apply this doctrine of State rights in this case, or rather, allow it to be applied by the States named above, and they could prevent the navigation of these waters by any but their own citizens or those to whom they might grant that privilege. If this doctrine of State rights is sound, these two States would have the right to levy tolls or duties on every vessel that sails those waters, as the State of New-York exacts tolls on her canals. Such power thus exercised, would cripple commerce, inconvenience the public, and utterly destroy all comity between the States. This exacting tolls for navigation of waters is one of the most offensive systems left us by past generations. It is so odious that modern governments decline to submit to it in cases where there is no doubt as to 'State rights,' as in that of the 'Sound Dues' exacted by Denmark. If, however, the State is supreme within its limits, it has a perfect right to exact such tolls. But no State in this nation has any such right under the Constitution. Its existence would destroy the Union by placing each State under the laws and exactions of either one of the others. The troubles growing out of such exactions would beget dispute; these disputes would beget open strife, which would end in open rupture and the downfall of the NATIONAL UNION. The 'UNITED STATES,' 'the Union,' 'the Nation,' are _supreme_. The States, _as States_, are subordinate; as 'parts,' they are inferior to the 'whole.' The 'State rights' doctrine is wrong, disorganizing, destructive of national life, and must be destroyed.
