On a first view the pretension is truly startling. There is no exception: the Rio Norte from its source to its mouth is declared to be the rightful boundary of Texas. That river has its source within the department, province, or state of New Mexico, which it traverses through its whole length from north to south, dividing it into two unequal parts. The largest and most populous, including Santa Fe, the capital, lies on the left bank of the river, and is therefore embraced within the claim of Texas. Now this province of New Mexico was first visited and occupied by the Spaniards under Vasquez Coronado, in the years 1540 to 1542. It was at that time voluntarily evacuated, subsequently re-visited, and some settlements made about the year 1583: finally conquered in 1595 by the Spaniards, under the command of Onate. An insurrection of the Indians drove away the Spaniards in the year 1680. They re-entered it the ensuing year, and after a long resistance re-conquered it. This was an internal conflict with the Aborigines; but as related to foreign powers, the sovereignty of the Spaniards over the territory was never called in question; and it was, in express terms, made the western boundary of Louisiana in the Royal Charter of the French Government. The conquest of the province by Onate, took place five-and-twenty years prior to the landing of the Pilgrims in New England, and twelve years before any permanent settlement had been made in North America, on the shores of the Atlantic, by either England, France, Holland, Sweden, or any other power, but that in Florida by Spain herself.
