The last story of an external soul which I shall notice comes from Nias, an island to the west of Sumatra, which we have visited more than once in the course of this book. Once on a time a chief was captured by his enemies, who tried to put him to death but failed. Water would not drown him nor fire burn him nor steel pierce him. At last his wife revealed the secret. On his head he had a hair as hard as a copper wire; and with this wire his life was bound up. So the hair was plucked out, and with it his spirit fled.(859) § 4.—The external soul in folk-custom. Thus the idea that the soul may be deposited for a longer or shorter time in some place of security outside the body, or at all events in the hair, is found in the popular tales of many races. It remains to show that the idea is not a mere figment devised to adorn a tale, but is a real article of primitive faith, which has given rise to a corresponding set of customs. We have seen that in the tales the hero, as a preparation for battle, sometimes removes his soul from his body, in order that his body may be invulnerable and immortal in the combat. With a like intention the savage removes his soul from his body on various occasions of real or imaginary danger. Thus we have seen that among the Minahassa of Celebes, when a family moves into a new house, a priest collects the souls of the whole family in a bag, and afterwards restores them to their owners, because the moment of entering a new house is supposed to be fraught with supernatural danger.(860) In Southern Celebes when a woman is brought to bed the messenger who fetches the doctor or the midwife always carries with him a piece of iron, which he delivers to the doctor. The doctor must keep it in his house till the confinement is over, when he gives it back, receiving a fixed sum of money for doing so. The piece of iron represents the woman’s soul, which at this critical time is believed to be safer out of her body than in it. Hence the doctor must take great care of the piece of iron; for if it were lost, the woman’s soul would assuredly, it is supposed, be lost with it.(861)
