But the immediate occasion of the most serious difficulty was the revival of the northeastern fisheries dispute. The century-long conflict as to the privileges of American fishermen in Canadian and Newfoundland waters, under the Treaty of 1783 and the Convention of 1818, had been set at rest during the era of Reciprocity (1854-66) by opening Canadian fishing-grounds to Americans, practically in return for free admission of Canadian natural products to the United States. Then once more, by the Treaty of Washington in 1871, access to the inshore fisheries was bartered for free admission of fish and fish-oil plus a money compensation to be determined by a commission. The commission met at Halifax in 1877, Sir A. T. Galt representing Canada, and the award was set at $5,500,000 for the twelve years during which the treaty was to last. The United States condemned the award with much heat, and took occasion to abrogate the clause of the treaty on the earliest date for which notice could be given, July 1, 1885. {105} For that season the fishing privileges were extended, but with the next year the whole dispute revived. The Canadian authorities insisted on restricting American fishermen rigidly to the letter of treaty privileges as Canada interpreted them. American fishing vessels were not only barred from fishing within the three-mile limit but were forbidden to enter a Canadian port to ship cargoes or for any other purpose, save for shelter, wood, water, or repairs. Several American boats were seized and condemned; and Canadian fishery cruisers patrolled the coasts, incessantly active. A storm of genuine if not informed indignation broke out in the United States. The action of the Canadian authorities was denounced as unneighbourly and their insistence on the letter of ancient treaties as pettifogging; and, with more justice, it was declared that the Canadian Government used the fishing privileges as a lever, or rather a club, to force the opening of the United States markets to all Canadian products. President Cleveland sought a friendly solution by the appointment of a joint commission. Congress, more bellicose, passed unanimously (1887) a Retaliatory Act, empowering the president, if satisfied that American vessels {106} were illegally or vexatiously harassed or restricted, to close the ports and waters of the United States against the vessels and products of any part of British North America. The president declined to fire this blunderbuss, and arranged for the commission on which Joseph Chamberlain, Sir Lionel Sackville-West, and Sir Charles Tupper were the British representatives. The draft treaty which the commission framed failed to pass the United States Senate, but a _modus vivendi_ was arranged permitting American vessels port privileges upon payment of a licence fee. This, together with more considerate conduct on both sides, eased the tension.
