It was Tom who acted. Heedless of the danger, he leaped forward and aimed a kick at the snake's head.
The reptile was caught fairly and squarely, and the head went down with an angry hiss. Then Tom stepped upon it, but the snake squirmed loose and uttered another hiss, louder than before.
"Take him off! Take him off!" screamed Sam, now recovering his voice.
"Don't let him bite me."
He would have caught the snake himself, and so would Tom, but the hands of both were still tied behind them.
By this time Captain Langless emerged from the cave, pulling out a pistol as he did so.
Arnold Baxter had not offered to fire a second shot. Now, he was out of danger himself, he did not seem to care what became of the Rovers.
Crack! crack! It was the captain's weapon which spoke up, and the two shots, fired in rapid succession, did their work thoroughly. The first took the snake in the neck and the second in the head, and in a twinkle the long, slippery body unwound itself from Sam's leg and began to turn and twist on the ground.
"Good for you!" gasped Sam, when able to speak again. "Ugh! what an ugly thing!" And he retreated to the opposite side of the pool, along with Tom.
"He was a nasty one," replied Captain Langless, as he coolly proceeded to reload his pistol. "I might have killed him in the cave, only the light was bad."
"Is he—he dead?" came from behind some rocks, and Dan showed a white face and trembling form.
