place north of the Rio Bravo, and within the territory claimed by the United States." He was instructed, should they be found in the country north of that river, to make known to them "the surprise with which the President has seen possession thus taken, without authority from the United States, of a place within their territorial limits, and upon which no lawful settlement can be made without their sanction." He was instructed to call upon them to "avow under what national authority they profess to act," and to give them due warning "that the place is within the United States, who will suffer no permanent settlement to be made there under any authority other than their own." As late as the 8th of July, 1842, the Secretary of State of the United States, in a note addressed to our minister in Mexico, maintains that by the Florida treaty of 1819 the territory as far west as the Rio Grande was confirmed to Spain. In that note he states that-- By the treaty of the 22d of February, 1819, between the United States and Spain, the Sabine was adopted as the line of boundary between the two powers. Up to that period no considerable colonization had been effected in Texas; but the territory between the Sabine and the Rio Grande being confirmed to Spain by the treaty, applications were made to that power for grants of land, and such grants or permissions of settlement were in fact made by the Spanish authorities in favor of citizens of the United States proposing to emigrate to Texas in numerous families before the declaration of independence by Mexico.
