As with shadows and reflections, so with portraits; they are often believed to contain the soul of the person portrayed. People who hold this belief are naturally loth to have their likenesses taken; for if the portrait is the soul, or at least a vital part of the person portrayed, whoever possesses the portrait will be able to exercise a fatal influence over the original of it. Thus the Esquimaux of Bering Strait believe that persons dealing in witchcraft have the power of stealing a person's shade, so that without it he will pine away and die. Once at a village on the lower Yukon River an explorer had set up his camera to get a picture of the people as they were moving about among their houses. While he was focusing the instrument, the headman of the village came up and insisted on peeping under the cloth. Being allowed to do so, he gazed intently for a minute at the moving figures on the ground glass, then suddenly withdrew his head and bawled at the top of his voice to the people, "He has all of your shades in this box." A panic ensued among the group, and in an instant they disappeared helterskelter into their houses. The Tepehuanes of Mexico stood in mortal terror of the camera, and five days' persuasion was necessary to induce them to pose for it. When at last they consented, they looked like criminals about to be executed. They believed that by photographing people the artist could carry off their souls and devour them at his leisure moments. They said that, when the pictures reached his country, they would die or some other evil would befall them. When Dr. Catat and some companions were exploring the Bara country on the west coast of Madagascar, the people suddenly became hostile. The day before the travellers, not without difficulty, had photographed the royal family, and now found themselves accused of taking the souls of the natives for the purpose of selling them when they returned to France. Denial was vain; in compliance with the custom of the country they were obliged to catch the souls, which were then put into a basket and ordered by Dr. Catat to return to their respective owners.
