It seems rather paradoxical that they should have loved one stranger so well as to spare him with suspicious kindness, and love others to the extent of making them into table delicacies. The explanation probably is that these Mangeromas were the reverse of a certain foreign youth with only a small stock of English, who, on being offered in New York a fruit he had never seen before, replied, "Thank you, I eat only my acquaintances"—the Mangeromas eat only their enemies.

Mr. Lange's account of his stay with these people, of their weapons, habits, form of battle, and method of cooking the human captives, etc., forms one of the specially interesting parts of the book, and is at the same time a valuable contribution to the ethnology of the western Amazon (or Marañon) region, where dwell numerous similar tribes little known to the white man. Particularly notable is his description of the wonderful wourahli (urari) poison, its extraordinary effect, and the modus operandi of its making; a poison used extensively by Amazonian tribes but not made by all. He describes also the bows and arrows, the war-clubs, and the very scientific weapon, the blow-gun. He was fortunate in securing a photograph of a Mangeroma in the act of shooting this gun. Special skill, of course, is necessary for the effective use of this simple but terrible arm, and, like that required for the boomerang or lasso, practice begins with childhood.

The region of Mr. Lange's almost fatal experiences, the region of the Javary River (the boundary between Brazil and Peru), is one of the most formidable and least known portions of the South American continent. It abounds with obstacles to exploration of the most overwhelming kind. Low, swampy, with a heavy rainfall, it is inundated annually, like most of the Amazon basin, and at time of high water the rivers know no limits. Lying, as it does, so near the equator, the heat is intense and constant, oppressive even to the native.
