Villariño named this river the Rio de la Encarnacion. By the Indians, it is called Limé-leubú, or the river of leeches: indeed they call the main stream so, during its whole course to the junction of the Neuquen; after which, they give it the appellation of Curi-leubú, the River Negro. They described it as proceeding from the great lake of Nahuel-huapi,[26] where, in the year 1704, the Jesuits established a mission, which was afterwards destroyed by some hostile savages, and the Fathers murdered. The vestiges of their habitations and chapel still remain, and that part of the country is called by the Indians Tuca-malal, probably from some allusion to the ruins; the inhabitants call themselves Huilliches, or the southern people. Through them, to Villariño's surprise, the Pehuenches Indians, whom he shortly afterwards fell in with, had already received accounts of the establishment of the Spaniards at San Julians; the news had doubtless been carried to them by the friendly Indians, with whom Viedma had been in communication at that place, and whom he speaks of in his diary as having gone northward on an expedition which lasted four months, to buy horses from the Indians in that direction. But if the Spaniards were surprised to hear these people speak of their countrymen at San Julians, 600 miles off, they were much more so, to be asked by them if the war between Spain and England was over. In this, however, it turned out that they had a more direct interest than might have been expected; certain articles of European manufacture which they had been in the habit of purchasing from the Valdivians having become scarce and dear, from the interruption of the trade of that place with Spain in consequence of the war. Who would have supposed that the Indians of Araucania could have known or cared whether England and Spain were at war or not? Having taken this cursory view of the Encarnacion, Villariño returned to continue his voyage up the northern branch of the Negro, which is called the Catapuliché by the Indians. It would perhaps be more correct to consider, as they do, the Encarnacion as the upper part of the Negro, and the Catapuliché as an affluent joining it from the opposite direction. Its shallowness prevented their making much way up it; after much labour and difficulty, in twenty days they had only advanced ten leagues, and then all hope of getting further was at an end. This was on the 17th of April, when they were in latitude 39° 40´, over against Valdivia. The Catapuliché runs along the base of the Cordillera, distant five or six miles; it is joined by several streams from the mountains, which irrigate the intervening slopes and plains, and form good pasture-grounds for the Indians; and here they found their old acquaintances, who had run away from them lower down the river; and who, nothing abashed by what had passed, came at once to the boats to beg for spirits and tobacco.
