Within, the men waited at their appointed places. Each tunnel had its quota of warriors, the number being divided evenly to assure a speedy and simultaneous exit. The Americans had elected to fight from the _maloca_ of the great chief, while the Brazilians and José were to garrison the doorway of the other house as soon as the warning came. Rand, wordless and imperturbable as ever, now was armed with a strong bow and plenty of new arrows with unpoisoned heads; and he, of course, would remain with his own countrymen. Thus, preparations completed, all settled themselves to the interminable hours of waiting. Up on the heaped earth near the doorway, which made the walls practically bullet-proof to a height of six feet and thus would protect the women and children, one or more of the Americans was constantly on the lookout through some inconspicuous loophole. Hour after hour dragged past, and no unusual movement or sound came to reward their vigilance. Under the glare of the sun the roof and walls grew hot; under the silent strain of endless anticipation the impatience of the fighting men became a ferment. At length Pedro, unable to keep still, mounted to a peephole near Knowlton. Scarcely had he put his eye to the opening when both men sucked in their breath. At the edge of the bush a man's head peered from behind a tree. And at the same moment a single canoe came creeping out of the bush and up to the landing place. The head behind the tree was that of a Red Bone spy. The two in the small canoe were Yuara and a companion from the Suba tribe. "Lourenço!" hoarsely whispered Pedro. "Yuara comes. Tell girls to run to welcome him and guide him between the pits. A spy is watching. If Yuara walks on the pits he dies and our trap is revealed. _Por amor de Deus_, send girls quickly!" Lourenço acted instantly. Seizing two young women, he propelled them doorward, talking swiftly the while. Yuara and his mate were already advancing innocently toward the few girls outside, none of whom had wit enough to warn him. But the two whom the Brazilian had grasped happened to be of quick intelligence, and now they darted out. Before the visiting pair could reach the death trap the girls were upon them, laughing as if delighted to see a man once more, and deftly turning them aside to the point where two unobtrusive stubs marked the bridge of safety. Vastly astonished by such effusive welcome from two girls whom they did not know, but by no means displeased thereby, the young warriors of the Suba clan were piloted to the door and inside. As they disappeared, the head of the spy also vanished. "Woof!" muttered Knowlton, wiping sweat from his brow. "That was close! Here's hoping we have no more visitors." Yuara and his companion meanwhile were being interrogated by both Lourenço and Monitaya, who in turn enlightened them as to the present state of affairs. At the promise of war the faces of the Suba men lit up.
