To those behind came a light rustle of leaves and a scuffle of moving feet; a sudden cessation; then Lourenço's voice speaking to some one concealed behind the intervening undergrowth. His tone was slow, quiet, easy--the tone which, even if the words were not understood, would soothe suspicious and abruptly alarmed minds. After another short silence he resumed talking, pointing carelessly to the place behind him where stood the silent file of Mayorunas. A guttural voice replied. A head peered cautiously from the edge of the bush, stared fixedly at Tucu, and withdrew. The voice sounded again. Immediately three Indians stepped into view, poised for action. Another interval of staring, and they relaxed. "Come forward, comrades," said Lourenço. They came, halting again at the junction of the trails. Tucu spoke to one of the newcomers, who scowled as if only partly understanding, but grunted some sort of answer. Those behind the Mayoruna leader craned their necks and scanned the Red Bone men, who continued to eye with evident misgiving the tall-bonneted cannibals and the broad-hatted pair of whites. Man for man, these Red Bones were in every way inferior to the emissaries of Monitaya. Their bodies were more gaunt, their skins more coppery, their foreheads lower, and their expressions much less intelligent. Furthermore, they wore not even the bark-cloth clouts which formed the sole body covering of the Mayorunas--they were totally naked. The one point of similarity between the two tribes was that the faces of the Red Bone men were streaked with red dye. But the facial design was much different: two short transverse stripes on the forehead, and three lines on each cheek, running from the eyes, the end of the nose, and the corners of the mouth, straight back to the ears. Studying those visages, Knowlton and McKay recalled Schwandorf's statement that these people not only ate human flesh, but tortured prisoners of war. It was easy to believe that he had told truth. McKay, standing behind Pedro, shifted his position a bit. At once the eyes of the three Red Bones widened and riveted on his face. Heretofore they had seen only his hat and eyes, the rest being hidden from them by Pedro's neck and an intervening palm tip. Now that they saw his black-bearded jaw, they started slightly and peered intently at him. "I think, Capitao, you would do well to shave," Pedro suggested, with a smile. "'Fraid so," the captain granted. "Black beards evidently are _de trop_ in the jungle social set at present." But then one of the Red Bone men came forward, still squinting narrowly, and his expression was not hostile. In fact, it was more friendly than it had yet been. After a closer scrutiny, however, his face turned blank. Slowly he stepped back and muttered something to his companions. At this Pedro's eyes narrowed speculatively. But his expression did not change, and he said nothing.
