Conversely, if the shadow is a vital part of a man or an animal, it may under certain circumstances be as hazardous to be touched by it as it would be to come into contact with the person or animal. Hence the savage makes it a rule to shun the shadow of certain persons whom for various reasons he regards as sources of dangerous influence. Amongst the dangerous classes he commonly ranks mourners and women in general, but especially his mother-in-law. The Shuswap Indians think that the shadow of a mourner falling upon a person would make him sick. Amongst the Kurnai of Victoria novices at initiation were cautioned not to let a woman's shadow fall across them, as this would make them thin, lazy, and stupid. An Australian native is said to have once nearly died of fright because the shadow of his mother-in-law fell on his legs as he lay asleep under a tree. The awe and dread with which the untutored savage contemplates his mother-in-law are amongst the most familiar facts of anthropology. In the Yuin tribes of New South Wales the rule which forbade a man to hold any communication with his wife's mother was very strict. He might not look at her or even in her direction. It was a ground of divorce if his shadow happened to fall on his mother-in-law: in that case he had to leave his wife, and she returned to her parents. In New Britain the native imagination fails to conceive the extent and nature of the calamities which would result from a man's accidentally speaking to his wife's mother; suicide of one or both would probably be the only course open to them. The most solemn form of oath a New Briton can take is, "Sir, if I am not telling the truth, I hope I may shake hands with my mother-in-law." Where the shadow is regarded as so intimately bound up with the life of the man that its loss entails debility or death, it is natural to expect that its diminution should be regarded with solicitude and apprehension, as betokening a corresponding decrease in the vital energy of its owner. In Amboyna and Uliase, two islands near the equator, where necessarily there is little or no shadow cast at noon, the people make it a rule not to go out of the house at mid-day, because they fancy that by doing so a man may lose the shadow of his soul. The Mangaians tell of a mighty warrior, Tukaitawa, whose strength waxed and waned with the length of his shadow. In the morning, when his shadow fell longest, his strength was greatest; but as the shadow shortened towards noon his strength ebbed with it, till exactly at noon it reached its lowest point; then, as the shadow stretched out in the afternoon, his strength returned. A certain hero discovered the secret of Tukaitawa's strength and slew him at noon. The savage Besisis of the Malay Peninsula fear to bury their dead at noon, because they fancy that the shortness of their shadows at that hour would sympathetically shorten their own lives.
