"The engagements entered into by a treaty ought," he said, "to be mutual, and equally binding on the respective contracting parties. It would, therefore, be the height of folly as well as injustice, to suppose one party alone obliged to a strict observance of the public faith, while the other might remain free to deviate from its own engagements as often as convenience might render such deviation necessary, though at the expense of its own credit and importance." He concluded with the assurance, "that whenever America should manifest a real determination to fulfil her part of the treaty, Great Britain would not hesitate to prove her sincerity to co-operate in whatever points depended upon her, for carrying every article of it into real and complete effect." This letter was accompanied by a statement of the infractions of the fourth article. Copies of both documents were immediately transmitted by Mr. Adams to congress, by whom they were referred to Mr. Jay, the secretary for foreign affairs. The report of that upright minister did not, by contravening facts, affect to exculpate his country. "Some of the facts," said he in a letter to General Washington, written after permission to communicate the papers had been given, "are inaccurately stated and improperly coloured; but it is too true that the treaty has been violated. On such occasions, I think it better fairly to confess and correct errors, than attempt to deceive ourselves and others, by fallacious though plausible palliations and excuses. "To oppose popular prejudices, to censure the proceedings and expose the impropriety of states, is an unpleasant task, but it must be done."[29] [Footnote 29: The facts relative to this negotiation were stated in the correspondence of General Washington. The statement is supported by the Secret Journals of Congress, vol. 4, p. 329, and those which follow.]
