Sam said nothing, but brought his rifle to his shoulder, took quick aim and pulled the trigger. The bullet sped true and buried itself in the boa-constrictor’s neck.

The shot awakened Darry to action and now he too blazed away, peppering the big snake in the head and body. The second shot from his gun was at close range and fairly tore a piece of skin from the huge reptile’s neck.

But a boa-constrictor is not easily killed, and though badly wounded it yet had a great deal of fight in it. Still holding to the tree branch with its tail it shot forth its body and in an instant had Hockley by the waist.

“Help! save me!” screamed the unfortunate youth. “Oh, please save me! Don’t let him crush me to pieces!”

In an agony of fear he tried to pull himself loose, but without avail. The snake lifted him up from the ground with ease, intending doubtless to crush him to a jelly on the tree trunk.

But now Sam rushed as close as had Darry. The rifle was a repeating weapon—one of the best the party possessed—and shoving it at the snake’s head the youth let drive twice in quick succession. Then, without waiting to see the effect of these shots, he put two additional bullets in the boa-constrictor’s body. The reptile quivered from head to tail then remained motionless.

It was an anxious moment and the hearts of all three boys seemed to stop beating. Hockley tried to call out, but could not, for the boa-constrictor was fairly crushing in his ribs.

But after that moment had passed the boys saw that they had won the battle. The head of the boa-constrictor dropped and the muscles of the huge body relaxed. Then Hockley slipped to the damp earth and slowly the reptile’s body dropped on top of him.

“He must be dead,” whispered Darry, hoarsely, and with his gun started to release Hockley from the loathsome weight. Sam assisted, and soon they had him free and was dragging him out of harm’s way. From a safe distance they watched the boa-constrictor and at last felt certain that it was dead.

“He’s in a bad way,” said Sam, leaning over Hockley. The youth lay in a heap, totally unconscious and breathing with difficulty.
