The early apprehensions with which Spain had contemplated the future strength of the United States, and the consequent disposition of the house of Bourbon to restrict them to narrow limits, have been already noticed. After the conclusion of the war, the attempt to form a treaty with that power had been repeated; but no advance towards an agreement on the points of difference between the two governments had been made. A long and intricate negotiation between the secretary of foreign affairs, and Don Guardoqui, the minister of his Catholic majesty, had terminated with the old government; and the result was an inflexible adherence on the part of Mr. Guardoqui to the exclusion of the citizens of the United States from navigating the Mississippi below their southern boundary. On this point there was much reason to fear that the cabinet of Madrid would remain immoveable. The violence with which the discontents of the western people were expressed, furnished Spain with additional motives for perpetuating the evil of which they complained. Aware of the embarrassments which this display of restlessness must occasion, and sensible of the increased difficulty and delay with which a removal of its primary cause must be attended, the executive perceived in this critical state of things, abundant cause for the exercise of its watchfulness, and of its prudence. With Spain, there was also a contest respecting boundaries. The treaty of peace had extended the limits of the United States to the thirty-first degree of north latitude, but the pretensions of the Catholic King were carried north of that line, to an undefined extent. He claimed as far as he had conquered from Britain, but the precise limits of his conquest were not ascertained. The circumstances attending the points of difference with Great Britain, were still more serious; because, in their progress, a temper unfavourable to accommodation had been uniformly displayed. The resentments produced by the various calamities war had occasioned, were not terminated with their cause. The idea that Great Britain was the natural enemy of America had become habitual. Believing it impossible for that nation to have relinquished its views of conquest, many found it difficult to bury their animosities, and to act upon the sentiment contained in the declaration of independence, "to hold them as the rest of mankind, enemies in war, in peace friends." In addition to the complaints respecting the violation of the treaty of peace, events were continually supplying this temper with fresh aliment. The disinclination which the cabinet of London had discovered to a commercial treaty with the United States was not attributed exclusively to the cause which had been assigned for it. It was in part ascribed to that jealousy with which Britain was supposed to view the growing trade of America.
