To the waiting Knowlton, Pedro, and Tucu it was briefly explained that preliminary negotiations had been concluded and that camp now would be made on the farther side of the creek. Tucu, observing that the Red Bone mass behind was dividing again to let the visitors pass through, gave the word to his men. The column began to move out, marching in reverse order. Pedro muttered swiftly to his partner. "Lourenço, see that house with the barred door where the clubman stands guard. Remember where it is." The other swept the loop in one quick glance, located the house, and fell into step without a word, the guarded structure fixed on his brain as clearly as if he had studied it for an hour. Walking down the malodorous street, he said, quietly, "There will be a small moon to-night." "You are becoming a reader of the mind, comrade," Pedro grinned. No more was said. Down to the shore of the creek trooped the party, followed closely by the hatchet-face and a score of tribesmen. The whites and the Mayorunas got into half a dozen of the waiting canoes and paddled across. In other dugouts the Red Bone men also crossed, but they did not land. As soon as the borrowed boats were empty the tribesmen took them in tow and returned to their own bank. The visitors were left on a partly cleared shore, separated from their uncordial hosts by some twenty yards of deep water. Not one canoe was left them. Furthermore, the Red Bones now began activities indicating an intention to establish a night-long watch on the irside of the stream. "Taking no chances of our raiding them to-night, or even snooping around town," said Knowlton. "Keeping everything in their own hands. Reckon we'd better post sentries to-night, Rod, just to keep an eye on that outpost of theirs." McKay nodded. "We four will take it in turn," he agreed. "Lourenço--Pedro--you--I. Three-hour tours." "Pardon, Capitao," interposed Pedro. "It would be well to change that. You two senhores take the first two watches." "Why?" frowned McKay. "Because Lourenço and I wish to go visiting. We are much smitten with the charms of the ladies here." The captain's frown deepened, but he studied Pedro's devil-may-care face keenly before answering. "Humph! What's up your sleeve? Out with it!" Pedro glanced around him and across the water. The tribesmen, both of the Mayoruna force and of the Red Bones, were watching the colloquy. "We are watched, Capitao. Let us make camp now and talk later. These men do not understand our words, but we cannot tell what they may see in our faces. Now speak harshly, as if I had been insolent." McKay did. He thundered at the young bushman as if about to do him bodily injury. Pedro retreated a step, as if taken aback by the storm he had unleashed. When McKay stopped he replied: "Excellent, Capitao. Now I go to start work on the _tambo_."
