Tivoli’s only reply was a sweep of the hand toward the blackening sky. As if in answer to his signal, there came crashing down upon them one of those sudden storms that are known only in the tropics.

“We’ll get away under cover of the storm,” said Pant. “That will be better still.”

“You don’t now these tropical storms,” said Tivoli. “All night in the rain fifteen men must work; fifteen men must rest, sleep beneath canvas in hammocks. Even with fifteen men we may not save the raft, tied up right here. You do not know the tropics. There will be water in the river, water in the sky. Which is river? Which is sky? You cannot tell. The river will rise like a tide. There will come down snags, great trees, palm trees, mahogany, yamra, black tamarind, santa maria, many, many snags. All night long, at the edge of the raft, we must fight these snags away. There will be no sleep for Tivoli tonight, and perhaps no logs for Mr. Johnny Thompson after that, either.”

Tivoli was right. Such a storm as this was! Nothing of the kind had ever been witnessed by the boys before. Flash after flash of lightning, water in sheets, in streams, great avalanches of water that one could all but swim through. Rolling thunder vied with the increasing roar of black waters. And after that came the snags! And how those Caribs did work!

All night, till the clock hand stood at three, they labored. Then the water began to subside.

Then, exhausted, they threw themselves upon the bare logs and slept.

“At dawn we are away,” muttered Tivoli.

All that night, regardless of the lightning that set the water all agleam, in spite of the deluge of rain that fell, the Mayas and their blindfolded captives drifted silently down that broad river which indeed was Rio Hondo.

Awnings of cloth, cunningly treated with the juice from the bark of the wild rubber tree, protected them from the rain. They were safe and dry. The river carried them onward. What more need they ask?
