Another fortnight elapsed, but Monroe made no further progress. Whenever he saw Fox the subjects in dispute were discussed; but news arrived that the Non-importation Act had passed both Houses of Congress, and the difficulty of obtaining favors was increased by the attempt at compulsion. Fox showed less and less willingness to concede principles, although he did not, as Monroe feared, declare that the Act relieved him from any promises he might have made or from the fulfilment of any hopes he might have held out. Thus the matter stood, balanced almost equally between opposite chances, when, May 31, 1806, news arrived from America that Monroe’s powers were superseded by the appointment of a special mission, in which he was to be associated with William Pinkney of Maryland. The blow to Monroe’s pride was great, and shook his faith in the friendship of Jefferson and Madison. Three years had elapsed since he had himself been sent abroad to share Livingston’s negotiations, and he had the best reason to know how easily the last comer could carry away the prizes of popularity. The nomination of a colleague warned him that he had lost influence at home, and that Jefferson, however well disposed, no longer depended on him. This was in substance the truth; but other and graver troubles were revealed in part to Monroe’s eyes when William Pinkney arrived in London June 24, bringing with him the new instructions which were to become the foundation of the treaty. These instructions[284] began by treating the Non-importation Act as at once a domestic and a foreign regulation, a pacific and a hostile act, a measure with which England had no right to be angry, and one which was calculated to anger her,--strictly amicable and at the same time sharply coercive. After this preamble, in which the threat was clearer than the explanation, followed an order precluding the possibility of successful negotiation. Monroe was to begin by imposing an ultimatum. The British government must expressly repudiate the right and forbid the practice of impressment, or not only could no treaty be made, but the Non-importation Act should be enforced. “So indispensable is some adequate provision for the case that the President makes it a necessary preliminary to any stipulation requiring a repeal of the Act shutting the market of the United States against certain British manufactures.”
