“Somehow, a fellow feels as if he were an intruder here, Ken. And doesn’t the locality fit the description Father Francisco gave us?”

“In a way, yes. But we’ve been saying that every time we come to a particularly impressive gorge.”

“This one tops them all, Ken. Well, do we go on?”

“I guess so,” Ken decided reluctantly. “Let’s leave a note here for Hap under a pile of stones. That bridge doesn’t look any too safe though, so we’ll have to check it before trying to cross.”

The two Scouts scribbled a message, placing it conspicuously near the bridge.

Pedro meanwhile, was repacking a duffle bag. The task finished, he led the burro to the entrance of the bridge. There the animal balked.

“Hey, wait!” Jack called. “That bridge may not be safe!”

Pedro either did not hear or understand the command. He tugged at the halter and succeeded in getting the timid burro started across the weaving suspension bridge.

To the horror of the two watchers, the withes underfoot suddenly gave way. The burrow crashed through.

Pedro clutched wildly for the supporting cables. His pack slipped from his shoulders.
