He leaped into a canoe, drove it headlong across, and dived for the tambo. Behind him the other figures dashed panting up to the landing. Tucu's voice rasped in swift commands. The fugitives swarmed into other dugouts. The Mayoruna men, still ignorant of the identity of these people, but assured by Tucu's voice and manner that they were not enemies, lowered their weapons and rushed for the water. Up in the town the yelling swiftly grew into a roar, and running figures came pelting toward the creek.

The canoes struck the bank. Some were partly filled, some empty and in tow. Into Pedro's canoe the whites bundled the Raposa, while the Mayorunas got into anything within reach. Lourenço appeared from nowhere and urged the Americans to open fire. As he spoke, arrows thudded into the ground and the water.

"Take this man and go!" rasped McKay. "We're losing our equipment, but—"

His rifle leaped to his shoulder. Flame spat from it. From the van of the charging Red Bones shrilled a death scream.

Again and again the captain's gun cracked. Knowlton's joined in. Before their rifles grew silent the blunt roar of Pedro's repeater broke out. And with the emptying of their long guns the Americans drew their short ones, and in a concerted ripping crash the forty-fives volleyed death and dismay into the oncoming cannibals.

The rush was checked. For a few seconds the Red Bones wavered and milled about. Into their mass poured a cloud of arrows and blowgun darts from the silent but no less deadly weapons of the Mayorunas. As the whites paused to reload, Pedro opened a new blast from Lourenço's rifle, which his comrade had passed to him on the run. Lourenço was not shooting, but working madly and alone to save the equipment. And, thanks to the renewed deadly fire of the guns, he saved it.

Before the wicked belch of the three rifles and the two automatics the Red Bones gave back more and more. Their arrows plunged all around the fighting men, but they fell at random, for the gunmen and the canoes were virtually invisible in the deep shadows. Downstream, Tucu's harsh voice jarred in commands as he straightened out the line of boats.

At the next lull in the firing Lourenço panted: "In, comrades! We are loaded. In!"

"Great guns! Are you still here?" snapped McKay. "I told you—"

"In! Talk later. Come!"
