Again, the _Manchi_, or medicine-man of the Peguenches and other Indian tribes in the Argentine Provinces, is skilled in the use of herbs. If remedies of this kind prove ineffectual, mysterious ceremonies are resorted to. A sheep and a colt are killed, and are placed with vessels of a fermented liquor, called _chichala_, under trees close to a hut; the patient is carried out of the hut and laid on the sunny side of the trees. The _Manchi_ and the women now dance in a circle round the trees, the animals, and the sick person. When the dancers are exhausted the _Manchi_ fumigates the animals and the sick person three times, and then sucks the diseased part of the man with such force as to draw blood. After this, he sucks the heart of the colt and anoints the sick person with the blood of the animal. At the conclusion of these disgusting ceremonies, in the performance of which the _Manchi_ affects to be in a trance, dancing is recommenced, and the patient is forced to join in it, supported by his friends. A general feast, in which the people consume the animals, concludes the ceremony.[47] The _Manchi_ generally uses a kind of drum in his incantations. The mystery-men of the Araucanian Indians are called _Gligua_, or _Dugol_, and some of them are distinguished by the epithets _Guenguenu_, _Genpugni_, and _Genpuri_ (_i. e._ "Master of the heavens, of epidemic diseases, of worms and insects,") and are supposed to have the power of curing every disease, of producing rain, and of preventing the ravages of worms and insects. The real medicine-men are called _Machi_,[48] and their method of curing is similar to that of the _Manchi_ of the Argentine Provinces just described. The ceremony is, however, always performed in the night. The hut in which the patient lies is lighted with a great number of torches. In a corner of the room is placed, among branches of laurel, a large bough of cinnamon, to which is suspended the magic drum; and near to it is a sheep which is to be killed for sacrifice. A number of women sing aloud and beat upon little drums, while the _Machi_ proceeds, with frightful gesticulations and horrible contortions of his body, to exorcise the evil spirit which is supposed to be the cause of the malady.[49] Sometimes he will suddenly exhibit in triumph a spider, a toad, or some other obnoxious animal, which he pretends to have extracted from the body of the sufferer.[50] A more detailed account of these impostors is unnecessary, especially as the works are mentioned which contain full descriptions of them.
