Hardly had he uttered the words, when the snake lifted it of itself a few inches from the white deck, and its whole body was in motion.

“Look out,” cried Jack; and several of the men started back, but the sailors who held the line stood fast, and drew the noose over the reptile’s head, and with a quick snatch tightened the strong cord about its neck.

The effect seemed magical, and the shot to have done nothing more than stun the creature for a time. It was now apparently as strong as ever, twining itself into knots and then writhing free again, to beat the white deck with its tail.

But this did not last many minutes, and as the men kept the line tight across the deck the reptile gradually stretched itself out, till it hung perfectly limp and almost motionless by the neck. Then a small cask was brought on deck, a stone jar of prepared spirit poured in, and the snake drawn over the mouth and allowed to sink in. Then the head of the cask was held ready and the tightened fishing-line cut short off. There was a hollow splash, and the cask was covered and secured.

“That’s specimen the first,” said the doctor, with a smile of satisfaction. “We shall have to fill that pickle-tub up before we go back, Jack. There, go and put away the gun and let’s have our fish.”

“I’ll take the gun, Mr Jack, sir,” said Edward, who had been watching all the proceedings with the greatest interest. “I must clean it before it’s put away.”

Jack handed him the piece, and the man whispered quickly—

“Mr Jack, sir; do please tell me to come.”

“What, with us? Impossible,” said Jack hastily. “You heard my father say that there was not room for another.”

“Yes, sir, of course, not room for another like him, but I’m nobody. I don’t want any room; I can sit down in the bottom, or kneel down. And I should be so useful, sir. I could cut up bait, or put on hooks, or take ’em off, or anything.”
