Hunting shamans was his favorite pastime and sport. A captured shaman was usually invited aboard his boat and received with honor. Glass would talk to him in a friendly manner, inquiring about his life, the number of his yéik (spirits), the extent of their strength and power, etc. Then he would announce that he was also a shaman who owned yéik and suggested that they compete against each other. Upon his order, a charged electric battery was brought out. The shaman was asked to hold the wires in his hands, while the two poles were being connected. The shaman’s body would begin to twist. His own people, witnessing his strange and funny poses and hearing his screams and moans, became frightened. The shaman himself learned a practical lesson about the power of his white colleague. But the captain did not stop at that. Shamans always left his boat with their heads shaved and covered with oil paint, and having promised not to practice shamanism anymore.
