(M46) Among the Yuracares, an Indian tribe of Bolivia, at the eastern foot of the Andes, when a girl perceives the signs of puberty, she informs her parents. The mother weeps and the father constructs a little hut of palm leaves near the house. In this cabin he shuts up his daughter so that she cannot see the light, and there she remains fasting rigorously for four days. Meantime the mother, assisted by the women of the neighbourhood, has brewed a large quantity of the native intoxicant called _chicha_, and poured it into wooden troughs and palm leaves. On the morning of the fourth day, three hours before the dawn, the girl’s father, having arrayed himself in his savage finery, summons all his neighbours with loud cries. The damsel is seated on a stone, and every guest in turn cuts off a lock of her hair, and running away hides it in the hollow trunk of a tree in the depths of the forest. When they have all done so and seated themselves again gravely in the circle, the girl offers to each of them a calabash full of very strong _chicha_. Before the wassailing begins, the various fathers perform a curious operation on the arms of their sons, who are seated beside them. The operator takes a very sharp bone of an ape, rubs it with a pungent spice, and then pinching up the skin of his son’s arm he pierces it with the bone through and through, as a surgeon might introduce a seton. This operation he repeats till the young man’s arm is riddled with holes at regular intervals from the shoulder to the wrist. Almost all who take part in the festival are covered with these wounds, which the Indians call _culucute_. Having thus prepared themselves to spend a happy day, they drink, play on flutes, sing and dance till evening. Rain, thunder, and lightning, should they befall, have no effect in damping the general enjoyment or preventing its continuance till after the sun has set. The motive for perforating the arms of the young men is to make them skilful hunters; at each perforation the sufferer is cheered by the promise of another sort of game or fish which the surgical operation will infallibly procure for him. The same operation is performed on the arms and legs of the girls, in order that they may be brave and strong; even the dogs are operated on with the intention of making them run down the game better. For five or six months afterwards the damsel must cover her head with bark and refrain from speaking to men. The Yuracares think that if they did not submit a young girl to this severe ordeal, her children would afterwards perish by accidents of various kinds, such as the sting of a serpent, the bite of a jaguar, the fall of a tree, the wound of an arrow, or what not.(135)
