Recovering from his stupor, Haverly made a dash for the turret; but, ere he could reach it, with a curling snap—for all the world like the crack of a whiplash—a giant feeler coiled about his waist.

High above the deck he was lifted, struggling desperately, yet vainly, against the grip of the suckers which seared his flesh like red-hot iron.

His fearful plight aroused his comrades to a sense of their own peril, and, as two more tentacles flashed over the rail, Seymour leapt into the wheelhouse.

Escaping by a miracle the writhing, groping arms of the cephalopod, and urged to action by the feeble groans of the American—fast becoming exhausted by the unequal struggle—Seymour entered the turret. Snatching down a couple of axes from the rack, he skimmed them towards his friends; then, with a third, he commenced a furious attack upon the nearest tentacle.

Two lusty blows, with all the baronet’s giant strength behind them, and the great arm fell with a whack across the deck, wriggling still, although severed from the monstrous, pulpy body which gave it life. Springing forward, the baronet was about to lop in twain the tentacle which held his friend, when the Seal heeled over, almost flinging him from the deck. With great difficulty he regained his balance; then a cry escaped him. Out of the water alongside came a huge, black body, armed with many more feelers. Slowly it dragged itself, clutching and clawing, over the rail, falling heavily inboard with a shock which threatened to capsize the Seal.

The octopus had come aboard!

There was something so weird, so uncanny in the appearance of the brute; something so diabolical about the writhing, twisting arms, as they groped and waved over the deck, that Seymour stood for an instant, half fascinated.

The creature’s great eyes glared like green lamps, and its parrot-like beak snapped viciously, while from its pulpy body came an overpowering odour of musk.

Suddenly a shrill cry of terror burst from Wilson. One of the great thrashing feelers had gripped him, and, dropping his axe in his deadly fear, the unfortunate engineer strove with all his strength to dislodge the suckers.

As he was dragged slowly towards that terrible beak, an inspiration swept into his brain.
