A like unfriendly disposition has been manifested on the part of Canada in the maintenance of a claim of right to exclude the citizens of the United States from the navigation of the St. Lawrence. This river constitutes a natural outlet to the ocean for eight States, with an aggregate population of about 17,600,000 inhabitants, and with an aggregate tonnage of 661,367 tons upon the waters which discharge into it. The foreign commerce of our ports on these waters is open to British competition, and the major part of it is done in British bottoms. If the American seamen be excluded from this natural avenue to the ocean, the monopoly of the direct commerce of the lake ports with the Atlantic would be in foreign hands, their vessels on transatlantic voyages having an access to our lake ports which would be denied to American vessels on similar voyages. To state such a proposition is to refute its justice. During the Administration of Mr. John Quincy Adams Mr. Clay unanswerably demonstrated the natural right of the citizens of the United States to the navigation of this river, claiming that the act of the congress of Vienna in opening the Rhine and other rivers to all nations showed the judgment of European jurists and statesmen that the inhabitants of a country through which a navigable river passes have a natural right to enjoy the navigation of that river to and into the sea, even though passing through the territories of another power. This right does not exclude the coequal right of the sovereign possessing the territory through which the river debouches into the sea to make such regulations relative to the police of the navigation as may be reasonably necessary; but those regulations should be framed in a liberal spirit of comity, and should not impose needless burdens upon the commerce which has the right of transit. It has been found in practice more advantageous to arrange these regulations by mutual agreement. The United States are ready to make any reasonable arrangement as to the police of the St. Lawrence which may be suggested by Great Britain.
