The Dyaks are very fond of blood-letting whenever there is pain in any part of the body or limb, and they have a method of “cupping” which is rather ingenious. The part from which the blood is to be drawn has incisions made in it with a small knife. The “cupping-glass” is a young wet bamboo which has a knot at one end, but is open at the other. This is heated at the fire, and then placed firmly over the incisions made in the flesh. Cold water is then poured on the bamboo, and it draws out the blood. The heat fills the bamboo with steam from its dampness. The cold water condenses this steam, and makes the bamboo an excellent “cupping-glass.” As the Dyak believes that all sickness is caused by the spirits, it is not surprising that his faith in medicines is small, and that he knows of few remedies, and depends for his cures either on the mysterious ceremonies of the witch-doctors or on charms which have been made known by the spirits to the fortunate owners by means of dreams. These charms are generally pebbles, roots, leaves, feathers, or bits of wood. The pebbles and roots are rubbed on the body, or else put in water and the water applied. The leaves, bits of wood, feathers, etc., are burnt, and the ashes rubbed on the affected part. Though the _manang_ depends upon his power over spirits to cure diseases, still he calls to his aid his numerous charms, which he claims to have received from the spirits. These valued treasures are carried in his _lupong_, or medicine-chest. The following excellent description of “The Contents of a Dyak Medicine-chest,” by Bishop Hose, under whom I worked for many years as a missionary to the Dyaks, is reproduced here by his kind permission. The place and the people mentioned in it are all well known to me, as the village of Kundong is in the Saribas District, which was in my charge for many years:—
