Among the equestrian nations out of Chaco, the first place is held by the Guenoas, who reside between the rivers Uruguay and Plata, and the Pacific Ocean, without, however, having any fixed settlements. This very numerous nation comprehends the Charruas, the Yaros, Bohanes, Minoanes, and Costeros, all horsemen, and of the most barbarous manners. These savages, as dwelling nearest the Rio de la Plata, and being, as it were, the door-keepers of all Paraguay, have ever given the most trouble to the new arrivers from Spain, to whom they are hostile in the highest degree. In 1750, the soldiers of Santa Fè, to revenge their frequent violation of the stipulated peace, surprized the perfidious Charruas, about morning, as they were sleeping in their tents. Many were slain, and the rest led into captivity with their families. On the western shore of the Parana, a village was built for them, about twenty leagues distant from the city, a priest given them to instruct them in religion and humanity, and a guard of soldiers added to secure his personal safety, and prevent their flight. The savages were chiefly supported by the flesh of wild horses, with which the neighbouring plains are overrun. Tamed by hunger and misery, the Charruas applied themselves to agriculture, and yielded conformity to their priest, who, fearing nothing farther for his own security, and that of the colony, desired that the soldiers might be removed, as he found their presence totally useless to himself, and extremely prejudicial to his proselytes. This good man, who was a Franciscan, knew that he should lose both cost and labour, if the Indians observed the manners and discourse of the soldiers incongruous with the precepts issued from the church. On the fear of hostile aggression, soldiers are sometimes sent from the city for the defence of a new colony; but we dreaded the coming of the soldiers, more than that of the savages. For the former by their licentiousness do more harm to the women, than the savages could do to the colony with all their weapons. About the end of the last century, men of our order, by their eloquence and kindness, so far brought over the barbarous Yaros, who form a large part of the Quenoas, that, collected in a little town dedicated to St. Andrew, they suffered themselves, for some time, to be instructed in religion; but at the instigation of a certain famous juggler, they returned to their old haunts. Being asked the cause of their flight, "We don't like," said they, "to have a God who knows and sees all we do in secret. It is our fixed resolve and pleasure to enjoy our old liberty of thinking and acting as we like." The massacres committed by these worst of savages, in the territories of Corrientes, Santa Fé, and Monte-Video, alike exceed belief and calculation.
