“We mean to go overboard, all of us, in a few minutes,” Magnus retorted, hugging Harry tightly with his left arm, which he had freed for that purpose. “Now I am going to propose something to you. Let us tie ourselves together with a rope so that each may help the other; and we may either live or perish together.”

“I am afraid you would be the loser by that arrangement,” his friend exclaimed. “You are a good deal stronger than I am, and you will need every bit of your strength if you are to plow your way through those awful breakers.”

Magnus, instead of answering, slipped the end of a rope about Harry’s waist and secured it tightly; the other end he tied about his own waist, although he came near losing his balance, and going headlong over the gunwale. The Cormorant had now slipped around to the leeward side of the island, where, under the shelter of the steep rock, the water was a trifle less tumultuous. And yet a gigantic surf was running and the undertow on the steeply sloping bottom seemed strong enough to take an elephant off his feet. The wind yelled and screeched from the top of the towering rock, and rushed down in thundering eddies on the leeward side. If it had not been for a momentary clearing of the sky, which showed the position of the breakers and the outline of the shore, it would have been madness to risk landing; and even as it was, the chance of being dashed to pieces against the rocks seemed altogether to preponderate. But Grim apparently took a different view of the situation; as long as the sail was whole and the boat true to her rudder he saw no cause for despair.

“Now, lads,” he roared, hoarsely, “steady on yer shanks. No chicken-hearted chap among ye! Uncoil the rope! Thar’s a bit of sandy beach thar—sixty or a hundred feet wide. If we be in luck we’ll be thar in a minute.”

The ridge of the island was now half visible against the dark horizon, but the beach below was wrapped in a dense smoke, through which came glimpses of the black jagged rock.

“Almighty Lord! thar’s a skerry ahead,” screamed one of the boatmen, as the retreating surf broke with a wild uproar over the hidden rock and rose like a mighty water-spout against the sky. There was a moment of breathless suspense. Each man seemed to hear the beating of the other’s heart. As the boat was flung upward again on the next wave, the wind gave a frantic shriek; the mast bent forward under the terrible strain. The incoming surf buried the skerry under a mountain of towering water, and high upon its crest The Cormorant rode triumphant, only to be hurled from its crest, fairly shooting through the air, upon the beach.

“Jump overboard!” bellowed Grim, and seizing Magnus in his arms he leaped from the stern just as the boat struck the sand and broke into fragments. Every man followed his example; but the undertow swept them off their feet. Still Grim stood like a rock, holding with his gigantic strength the rope to the other end of which Harry was attached. Once he tottered, and if he had had sand under his feet he would have been dragged down by his double burden. But by a lucky chance he had planted his heels upon a bowlder which rose slightly out of the surf. When the wildest force of the wave had been exhausted he sprang up on the beach, depositing Magnus and the half-unconscious Harry beyond the reach of the waves. Back he rushed again to his former station, just as one of the boatmen, who had momentarily regained his footing, was scrambling up toward him.

“I am tied to the rope,” shouted the man; “someone is tugging at it.”

“Hand it to me,” commanded Grim.
