(M11) While the mountaineer Indians of South America imagine that they can rid themselves of their fatigue in the shape of a stick or a stone, other or the same aborigines of that continent believe that they can let it out with their blood. A French explorer, who had seen much of the South American Indians, tells us that “they explain everything that they experience by attributing it to sorcery, to the influence of maleficent beings. Thus an Indian on the march, when he feels weary, never fails to ascribe his weariness to the evil spirit; and if he has no diviner at hand, he wounds himself in the knees, the shoulders, and on the arms in order to let out the evil with the blood. That is why many Indians, especially the Aucas [Araucanians], have always their arms covered with scars. This custom, differently applied, is almost general in America; for I found it up to the foot of the Andes, in Bolivia, among the Chiriguana and Yuracares nations.”(36) (M12) But it is not mere bodily fatigue which the savage fancies he can rid himself of by the simple expedient of throwing a stick or a stone. Unable clearly to distinguish the immaterial from the material, the abstract from the concrete, he is assailed by vague terrors, he feels himself exposed to some ill-defined danger on the scene of any great crime or great misfortune. The place to him seems haunted ground. The thronging memories that crowd upon his mind, if they are not mistaken by him for goblins and phantoms, oppress his fancy with a leaden weight. His impulse is to flee from the dreadful spot, to shake off the burden that seems to cling to him like a nightmare. This, in his simple sensuous way, he thinks he can do by casting something at the horrid place and hurrying by. For will not the contagion of misfortune, the horror that clutched at his heart-strings, be diverted from himself into the thing? will it not gather up in itself all the evil influences that threatened him, and so leave him to pursue his journey in safety and peace? Some such train of thought, if these gropings and fumblings of a mind in darkness deserve the name of thought, seems to explain the custom, observed by wayfarers in many lands, of throwing sticks or stones on places where something horrible has happened or evil deeds have been done. When Sir Francis Younghusband was travelling across the great desert of Gobi his caravan descended, towards dusk on a June evening, into a long depression between the hills, which was notorious as a haunt of robbers. His guide, with a terror-stricken face, told how not long before nine men out of a single caravan had been murdered, and the rest left in a pitiable state to continue their journey on foot across the awful desert. A horseman, too, had just been seen riding towards the hills. “We had accordingly to keep a sharp look-out, and when we reached the foot of the hills, halted, and, taking the loads off the camels, wrapped ourselves up in our sheepskins and watched through
