“It’s gone—the map’s gone!” he gasped.

“So that’s why the other party stopped following. That’s why Whackey isn’t around!” exclaimed the chief of the party.

“I saw him, today,” Nicky cried, and explained, “Tom did, too.”

“Planned to cut away during the night,” Bill snapped, “Guess he planned deeper, too: I think he expected these natives to make enough noise to be caught—that gave him a chance to get the map. I wondered why he watched me so closely, last couple of days.”

“Well, never mind,” Mr. Whitley counseled, “He and the others he went to join cannot get there ahead of us. Bill knows the passes.”

“All but one place after we get back to the snowy pass,” Bill objected, “Cliff’s pa only drew it rough and indicated the one right way—the way he took; but I know there’s a regular slather of cross cuts and paths between the cliffs up there. It’s all torn up by some earthquake long ago. I’d need the map there!”

“Well, we have the copy Tom made—” but Mr. Whitley stopped, arrested by Cliff’s clutch on his arm. Flashlights trained, the five, with a solemn warning to the natives, who seemed not to know what to do and so were for the time in no danger of mischief, hurried into Cliff’s tent. They flicked their lights around but Cliff, catching one from Nicky, trained it on the ground cloth.

Tiny fragments of paper, too fine ever to match together, littered the cloth under Tom’s little writing case!

CHAPTER VII
CLIFF TRIES A RUSE

When Quipu Bill questioned the Peruvians they remained sullenly wordless. What he called the vanished Whackey was, fortunately, expressed in Spanish; otherwise it would have called for reproof from Mr. Whitley.
