Oscar Peschel, in his "Races of Man," says that "perhaps the Brazilian Botocudos, of all the inhabitants of the world, are most nearly in the primitive state, and yet," he adds, "possibly we may be altogether mistaken in this regard, as their languages are very imperfectly known." Humboldt rescued the Caribs from such an impeachment and declares that their language "combines wealth, grace, strength, and gentleness. It has expressions for abstract ideas, for Futurity, Eternity, and Existence, and enough numerical terms to express all possible combinations of our numerals." It might be noted in passing that it was these same Brazilian natives that the Portuguese settlers sought to decimate by spreading smallpox and scarlet fever amongst them, as the English colonists in Tasmania shot the natives when they had no better food for their dogs. Hariot says that "many of the Indian natives of North and South America believe that the soul, after its separation from the body, enters into a wide path crowded with spirits which are journeying toward a region of eternal repose. They have to cross an impetuous river on a trembling wicker bridge which is very dangerous." Some Greenlanders believe that the soul can go astray out of the body for a considerable time. Some believe that they can leave their souls at home when going on a journey, and others believe in the migration of souls. Belief in the soul and a future state is universal among the Indians of North America. All are familiar with the tradition of the "Happy Hunting Ground." With them the future life is patterned after the present. Schoolcraft says that the Chippewas believe that there are duplicate souls, one of which remains with the body, while the other is free to depart on excursions during sleep. After death the soul departs to the Indian Elysium and a fire is kept burning on the newly-made grave for four days, the time required for the soul to reach its destination. The Dakotas stand in great fear of the spirits of the dead, who they think have power to injure them, and they recite prayers and give offerings to appease them.
