But to return to the Prophet. His fame, bruited far and wide, soon aroused the jealousy of many of the neighboring chiefs and medicine men. They saw their power dwindling away and their authority diminishing. They took steps to check the advancing tide of fanaticism, but were at once adroitly met by the introduction of an inquisition into witchcraft, which had been almost universally believed in by the tribes, but against which the Prophet now hurled the most direful anathemas. He declared that anyone who dealt in magic or "medicine juggleries" should never taste of future happiness, and must be instantly put to death. His deluded and awe-struck followers promptly began a systematic searching out and persecution of "witches," and all under his personal direction. The finger of the seer often pointed at a prominent warrior or chieftain, or some member of their household. The Prophet's mere denunciation was proof enough. The victim went to the torture of death by fire, or some other fate equally revolting. Among the Delawares, especially, the most shocking cruelty ensued, and finally these things came to the ears of the Governor at Vincennes. He immediately sent a "speech" by special messenger to the headmen and chiefs of the Delaware tribe beseeching them to cast aside all fallacious doctrines, to denounce the Prophet and to drive him out of their midst. In the course of this "speech" he said: "Demand of him some proof at least, of his being the messenger of the Deity. If God has really employed him, He has doubtless authorized him to perform miracles that he may be known and received as a prophet. If he is really a prophet, ask of him to cause the sun to stand still, the moon to alter its course, the rivers to cease to flow, or the dead to rise from their graves."
