"'While my Indian cook was preparing the afternoon meal, out from the dense jungle strode a bearded, shaggy-haired, painted white man, totally nude save for a narrow breechclout and a quiver containing several long hunting arrows. In one hand he carried a strong bow of really excellent workmanship. This was his only weapon. He wore no ornament, unless streaks of brilliant red paint be considered ornaments. He was wild and savage in appearance and manner as any cannibal Indian. Yet he was indubitably white. "'To my somewhat startled greeting he made no response. Neither did he speak at any time during his unceremonious visit. Bolt upright, he stood beside my crude table until the Indian stolidly brought in my food. Then, without a by-your-leave, the wild man rapidly wolfed down the entire meal, feeding himself with one hand and holding his bow ready in the other. Though I questioned him and sought to draw him into conversation, he honored me with not so much as a grunt or a gesture. When the table was bare he stalked out again and vanished into the dim forest. "'After he had gone my Indian urged that we leave the place at once. The man, he said, was "The Raposa"--a word which denotes a species of wild dog sometimes found on the upper Amazon. He knew nothing of this "Raposa" except that he apparently belonged to a wild tribe living far back in the forest, perhaps allied with the cannibal Mayorunas, who were very fierce; and that he appeared sometimes at Indian settlements, where, without ever speaking, he would help himself to the best food and then leave. My man seemed to fear that now some great misfortune would come to us unless we shifted our base. When the fever came upon me soon afterward, the superstitious fellow was convinced that the illness was attributable directly to the visit of the human "wild dog." "'Aside from the nudity and barbarism of the mysterious stranger, certain personal peculiarities struck me. One was that his eyes were green. Another was a streak of snow-white hair above one ear. Furthermore, the red paint on his body outlined his skeleton. His ribs, spine, arm- and leg-bones all were portrayed on his tanned skin by those brilliant red streaks. In this connection my Indian asserted that in the tribe to which "The Raposa" probably belonged it was the custom to preserve the bones of the dead and to paint them with this same red dye, after which the bones were hung up in the huts of the deceased instead of being given burial. Beyond this my informant knew nothing of the "Red Bone" people, except that to enter their country was death.'" Knowlton returned the book to his pocket and carefully buttoned the flap.
