It's the Black Robes who are making us die by their spells. Listen to me, I will prove it by reasons that you will recognize as true. They set themselves up in a village where everyone is feeling fine; no sooner are they there, but everyone dies except for three or four people. They move to another place, and the same thing happens. They visit cabins in other villages, and only those where they have not entered are exempt from death and illness. Don't you see that when they move their lips in what they call prayer, spells are coming out of their mouths? It's the same when they read their books. They have big pieces of wood [guns] in their cabins by which they make noise and send their magic everywhere. If they are not promptly put to death, they will end up ruining the country, and no one will be left, young or old. . . .

When she stopped speaking, everyone agreed that this was true, . . . [and] it seemed true . . . , for wherever the [Jesuit] Fathers went, God permitted death to accompany them so as to render more pure the faith of those who converted.
