A few minutes later the three crept out behind the tambo, Tucu gripping McKay's machete. As a final word Lourenço said: "Our men here may move about a little after a time, but do not try to keep them quiet. It is a part of the plan."

With that he was gone. Listen as they might, the Americans could hear no sound to indicate that three men now were traversing the black tangle beyond.

McKay took up his rifle and assumed the sentry work. Knowlton sat in his hammock, grateful for the chance to rest his weary legs. From the hammock where the Raposa lay no sound came. With a worried frown the lieutenant leaned over him and laid hand on his heart. After a while he sat up again in relief.

"Lord! I sure knocked him cold!" was his thought. "But he's still with us, and there's no use in reviving him now; the less noise over here the better. Hope I didn't jar his brains loose altogether; he might wake up a murderous maniac. Poor devil! A millionaire, yet half starved and more than half nutty."

He glanced at the dim scene before the hut. The moon now had journeyed so far westward that the creeping shadows of the tall trees had moved out almost to the creek, and the two crude shelters and the sentinel were surrounded by dense gloom. The Red Bone men opposite must rely on their ears alone hereafter, for they could not see through this darkness. McKay was visible enough to his own party, but not to the enemy. The blond man in the hammock watched the somber figure of his comrade, followed the flight of a big firefly whose light floated near, thought of the two bushmen out in the dark, and looked again at the still form of Rand.

"Drifters all," he soliloquized. "The fireflies and Rod and Tim and I and those Brazilian dare-devils—all floating around because we can't keep still, and never getting anywhere. And you, you silly-ass Rand, have a mint waiting for you up home, and we have to come find you and lead you up there and shove your nose into it. And if you get your brains back you'll be a nine days' wonder and a hero of the jungle and all that, and the girls will all tumble over you—because you've got a couple of millions in your sock. And we fellows who yanked you out of hell by the left hind leg can pocket our pay and go jump off the dock, for all anybody cares. Ho-hum! All the same, I'd rather be me than you, old thing. Free to drift and able to handle myself. You can have the money and the moths that hang around it."

With which he yawned, squinted again at the sinister figure squatting out yonder in the moonshine, arose, and made himself useful. Working very quietly, he took down three of the hammocks, rolled them up, laid them at the corner nearest the creek; made up the packs by sense of touch and placed them and the rifles of the absent pair in the same place. Then he lifted the Raposa from the one remaining hammock, laid him on the packs, rolled up the hammock itself, and put it under the unconscious man's head. If given time when the crisis came, he meant to save all equipment. If not, Rand lay where he could be grabbed without delay.

Before he completed the work he became aware that the Mayorunas all were awake. Not only awake, but moving stealthily about, as Lourenço had predicted. McKay also knew it and stepped back into the hut, where Knowlton told him what he had done. But so softly did the men of Monitaya move that the Red Bone watchers showed no sign of alarm. Both the Americans observed, however, that the cannibals across the stream had their heads together and that occasionally one looked up at the little moon.

"Get that, Rod? They're waiting for the shadows to crawl over there and cover them and the water. They know that then we can't see what they're up to. I'm betting they intend to pull some dirty work after that."

"Yep. But intention and accomplishment are two different birds. Wonder what these Mayorunas are fixing to do. Wish I could talk their language."
