Taken by surprise from the rear, the snake had one complete turn around the animal's body before there was any show of resistance, and then ensued a most thrilling conflict.

The boys could see that the boa's tail was fastened firmly around a tree, thus giving him a purchase such as the jaguar would have difficulty in overcoming.

Using both claws and teeth the animal defended himself bravely for ten minutes, and then it could be seen that the rapidly tightening folds of the serpent were hampering his movements. He no longer struggled so desperately; but uttered shrill cries of alarm which were responded to from a distance.

"His mate is coming," Poyor whispered. "Now we shall see a royal battle."

It was as he had said. A few moments later another jaguar appeared, and the boys could understand that the boa was making haste to crush the first victim before meeting the second enemy.

It was possible to see the muscles of the serpents' tail stand out as the pressure was increased, and then could be plainly heard the breaking bones while the victim uttered wild screams of agony.

The female jaguar had but just come into view when her mate was killed, and she darted at the serpent with a yell of rage which was answered by an angry hiss.

Whether the boa was taken at a disadvantage in the beginning of the fight, or had become so weary with its previous exertions as to render it incapable of putting forth all its powers could not be told; but certain it is that the second battle was short.

The beast caught it by the neck at the third attempt, and the lashing of the monster's tail told that he was beaten.

"He killed one jaguar easily; but this last beast will soon finish him," Teddy whispered, and almost before the words had been uttered the battle was virtually at an end.
