“Help! Help!”

Austin rushed toward him, and with the assistance of the Major, dragged him up again on the tree.

“What’s the matter?” they asked.

“Alligators! alligators!” replied Wilson.

The whole foot of the tree appeared to be surrounded by these formidable animals of the Saurian order. By the glare of the flames, they were immediately recognized by Paganel, as the ferocious species peculiar to America, called CAIMANS in the Spanish territories. About ten of them were there, lashing the water with their powerful tails, and attacking the OMBU with the long teeth of their lower jaw.

At this sight the unfortunate men gave themselves up to be lost. A frightful death was in store for them, since they must either be devoured by the fire or by the caimans. Even the Major said, in a calm voice:

“This is the beginning of the end, now.”

There are circumstances in which men are powerless, when the unchained elements can only be combated by other elements. Glenarvan gazed with haggard looks at the fire and water leagued against him, hardly knowing what deliverance to implore from Heaven.

The violence of the storm had abated, but it had developed in the atmosphere a considerable quantity of vapors, to which electricity was about to communicate immense force. An enormous water-spout was gradually forming in the south—a cone of thick mists, but with the point at the bottom, and base at the top, linking together the turbulent water and the angry clouds. This meteor soon began to move forward, turning over and over on itself with dizzy rapidity, and sweeping up into its center a column of water from the lake, while its gyratory motions made all the surrounding currents of air rush toward it.

A few seconds more, and the gigantic water-spout threw itself on the OMBU, and caught it up in its whirl. The tree shook to its roots. Glenarvan could fancy the caimans’ teeth were tearing it up from the soil; for as he and his companions held on, each clinging firmly to the other, they felt the towering OMBU give way, and the next minute it fell right over with a terrible hissing noise, as the flaming branches touched the foaming water.
