It has been claimed by Her Majesty's officers that the fishing vessels of the United States have no right to enter the open ports of the British possessions in North America, except for the purposes of shelter and repairing damages, of purchasing wood and obtaining water; that they have no right to enter at the British custom-houses or to trade there except in the purchase of wood and water, and that they must depart within twenty-four hours after notice to leave. It is not known that any seizure of a fishing vessel carrying the flag of the United States has been made under this claim. So far as the claim is founded on an alleged construction of he convention of 1818, it can not be acquiesced in by the United States. It is hoped that it will not be insisted on by Her Majesty's Government. During the conferences which preceded the negotiation of the convention of 1818 the British commissioners proposed to expressly exclude the fishermen of the United States from "the privilege of carrying on trade with any of His Britannic Majesty's subjects residing within the limits assigned for their use;" and also that it should not be "lawful for the vessels of the United States engaged in said fishery to have on board any goods, wares, or merchandise whatever, except such as may be necessary for the prosecution of their voyages to and from the said fishing grounds: and any vessel of the United States which shall contravene this regulation may be seized, condemned, and confiscated, with her cargo." This proposition, which is identical with the construction now put upon the language of the convention, was emphatically rejected by the American commissioners, and thereupon was abandoned by the British plenipotentiaries, and Article I, as it stands in the convention, was substituted. If, however, it be said that this claim is founded on provincial or colonial statutes, and not upon the convention, this Government can not but regard them as unfriendly, and in contravention of the spirit, if not of the letter, of the treaty, for the faithful execution of which the Imperial Government is alone responsible. Anticipating that an attempt may possibly be made by the Canadian authorities in the coming season to repeat their unneighborly acts toward our fishermen, I recommend you to confer upon the Executive the power to suspend by proclamation the operation of the laws authorizing the transit of goods, wares, and merchandise in bond across the territory of the United States to Canada, and, further, should such an extreme measure become necessary, to suspend the operation of any laws whereby the vessels of the Dominion of Canada are permitted to enter the waters of the United States.
