Cliff leaped forward and caught Tom, steadying him as he regained his breath. Bill swung and pointed his weapon straight at the Inca.

“You get back,” he said meaningly in quichua, “or this magic stick will speak and send you to your fathers!”

The Inca wavered uncertainly; but Challcuchima thrust between Cliff and Tom, Nicky raced to his assistance, Huamachaco cried out, “Capture the one who calls a white stranger his father!” and the entire crowd surged forward.

Bill and Mr. Whitley leaped up on the steps in concerted action and so sudden and unexpected was the rush that they upset one soldier who clutched at his comrade. Both fell. Bill gave the Inca a poke and he tottered down the side steps.

But others were ready to rush in.

Cliff spoke swiftly to his comrades, drew a paper of matches from his pocket; the crowd hesitated as he struck a match, backed to the cleared space behind them that offered a way to the temple steps. The soldiers had not yet closed in behind them.

Cliff did not speak; but his upflung hand caused curiosity in the minds of the simple natives.

Even the soldiers held quiet, an officer muttering some word to stay them. Methodically Cliff drew a squat, stubby paper tube from his robe. He handed it to Nicky; another to Tom.

“Light the fuses when I strike the match,” he whispered. “Then throw them down in front of us and all make for the doorway!”

He drew out a third tube, struck a match. Three fuses came together. But at the same instant a soldier leaped forward to jostle Cliff’s arm. But the fuses caught.
