From Father Borie

From Father Borie, Cameron learnt that the Jakun (by whom M. Borie probably means the Mantra) have a fixed and singular superstition concerning tigers, ninety-nine men out of every hundred believing it, even in the face of their Christian teaching. They believe that a tiger in their paths is invariably a human being, who having sold himself to the Evil Spirit, assumes by sorcery the shape of the beast to execute his vengeance or malignity. They assert that invariably before a tiger is met, a man has been or might have been seen to disappear in the direction from which the animal springs.
