Before we continue our story, it is indispensable for us to give our readers certain important and indispensable details about facts that have to come. Among the provinces of the vast territory of New Spain, there is one, the most eastern of all, whose real value the Government of the Viceroys has constantly ignored. This ignorance was kept up by the Mexican Republic, which, at the period of the proclamation of Independence, did not think it worthy of being formed into a separate state, and, without dreaming of what might happen at a later date, negligently allowed it to be colonized by the North Americans, who even at that period seemed infected by that fever of encroachment and aggrandizement which has now become a species of endemic mania among these worthy citizens--we refer to Texas. This magnificent country is one of the most fortunately situated in Mexico; territorially regarded, it is immense, no country is better watered, for considerable rivers pour into the sea, their waters swollen by countless streams which fertilize this country, as they traverse it in every direction; and these currents and rivers being deeply imbedded, never form those wide expanses of water by their overflow, which in other countries are transformed into fetid marshes. The climate of Texas is healthy, and exempt from those frightful diseases which have given such a sinister celebrity to certain countries of the New World. The natural borders of Texas are the Sabina on the East, Red River on the north, to the west a chain of lofty mountains, which enters vast prairies, and the Rio Bravo del Norte, and lastly, from the mouth of the latter river to that of the Sabina, the Gulf of Mexico. We have said that the Spaniards were almost ignorant of the real value of Texas, although they had been acquainted with it for a very long time, for it is almost certain that in 1536, Cabeça de Vaca traversed it when he proceeded from Florida to the northern provinces of Mexico. Still the honour of the first settlement attempted in this fine country belongs incontestably to France. In fact, the unfortunate and celebrated Robert de la Salle, ordered by the Marquis de Siegnelay to discover the mouth of the Mississippi in 1684, made a mistake, and entered the Rio de Colorado, which he descended with countless difficulties, till he reached the San Bernardo lagoon, where he built a fort between Velasco and Matagorda, and took possession of the country. We will enter into no further details about this bold explorer, who twice attempted to reach the unknown lands to the east of Mexico, and was traitorously assassinated in 1687, by villains who belonged to his band.
