“Strikes me it only takes one to kill a shark,” said the doctor quietly. “Your lance there, Jack.”

“No, no, doctor—you,” cried Jack excitedly.

“Don’t lose the chance, Mr Jack. Be ready, sir. Haul, my lads. Put your foot on the thwart, sir. Now then! Let him have it.”

Jack stood there flushing with excitement, and with his eyes dilated, following out his instructor’s orders to the letter, till, startled at the aspect of the monster being brought close up astern, he was ready to shrink from his task.

But he did not. As the mate spoke he thrust the lance down with excellent aim, feeling the keen blade pierce into the great fish’s side, and then seeming to dart out again.

“Give it him once more. Well done, sir. Bravo! Now another.”

Jack, in his excitement, thrust twice to the mate’s orders, and each time the dangerous brute made a feeble rush, but the harpoon held firm, and the last thrusts were fatal. The water was dyed with blood, and the shark turned up, showing all white in the ruddy surface; its tail quivered a little, and its career was over.

A cheer, headed by Edward, rang out, and the beast was examined before being cast loose, a clever cut or two from Lenny’s knife setting the harpoon at liberty.

Then, as the dead fish floated away, a good ten feet in length, the tub was replaced astern, and the dummy brought into requisition for a repetition of the novel fishing.

“My turn now,” said the doctor.
