Erik gave a cry and threw himself on his knees beside Patrick O'Donoghan, seeking for some sign of life, a ray of hope. But the Irishman was certainly dead this time, and that without revealing his secret.

As for Tudor Brown, one convulsion shook his body, his gun fell from his hands, in which he had tightly held it at the moment of his fall, and he expired without a word.

"Father, what have you done?" cried Erik, bitterly. "Why have you deprived me of the last chance that was left to me of discovering the secret of my birth? Would it not have been better for us to throw ourselves upon this man and take him prisoner?"

"And do you believe that he would have allowed us to do so?" answered Mr. Hersebom. "His second shot was intended for you, you may be sure. I have avenged the murder of this unfortunate man, punished the criminal who attempted to shipwreck us, and who is guilty perhaps of other crimes. Whatever may be the result, I do not regret having done so. Besides of what consequence is the mystery surrounding your birth, my child, to men in our situation? The secret of your birth before long, without doubt, will be revealed to us by God."

He had hardly finished speaking, when the firing of a cannon was heard, and it was re-echoed by the icebergs. It seemed like a reply to the discouraging words of the old fisherman. It was doubtless a response to the two gunshots which had been fired on their island of ice.

"The cannon of the 'Alaska!' We are saved!" cried Erik, jumping up and climbing a hummock to get a better view of the sea that surrounded them.

He saw nothing at first but the icebergs, driven by the wind and sparkling in the sunshine. But Mr. Hersebom, who had immediately reloaded his gun, fired into the air, and a second discharge from the cannon answered him almost immediately.

Then Erik discovered a thin streak of black smoke toward the west, clearly defined against the blue sky. Gunshots, answered by the cannon, were repeated at intervals of a few minutes, and soon the "Alaska" steamed around an iceberg and made all speed toward the north of the island.

Erik and Mr. Hersebom, weeping for joy, threw themselves into each other's arms. They waved their handkerchiefs and threw their caps into the air, seeking by all means to attract the attention of their friends.

At length the "Alaska" stopped, a boat was lowered, and in twenty minutes it reached their island.

Who can describe the unbounded joy of Dr. Schwaryencrona, Mr. Bredejord, Mr. Malarius, and Otto when they found them well and safe; for through the long hours of that sad night they had mourned them as lost.

They related all that had befallen them--their fears and despair during the night, their vain appeals, their useless anger. The "Alaska" had been found in the morning to be almost entirely clear of the ice, and they had dislodged what remained with the assistance of their gunpowder. Mr. Bosewitz had taken command, being the second-officer, and had immediately started in search of the floating island, taking the direction in which the wind would carry it. This navigation amidst floating icebergs was the most perilous which the "Alaska" had as yet attempted; but thanks to the excellent training to which the young captain had accustomed his crew, and to the experience which they had acquired in maneuvering the vessel, they passed safely among these moving masses of ice without being crushed by them. The "Alaska" had had the advantage of being able to travel more swiftly than the icebergs, and she had been able to benefit by this circumstance. Kind Providence had willed that her search should not prove fruitless. At nine o'clock in the morning the island had been sighted. They recognized it by its shape, and then the two shots from the guns made them hopeful of finding their two shipwrecked friends.

All their other troubles now appeared to them as insignificant. They had a long and dangerous voyage before them, which they must accomplish under sail, for their coal was exhausted.

"No," said Erik, "we will not make it under sail. I have another plan. We will permit the ice island to tow us along, as long as she goes toward the south or west. That will spare us incessantly fighting with the icebergs, for our island will chase them ahead of her. Then we can collect here all the combustibles that we will require in order to finish the voyage, when we are ready to resume it."

"What are you talking about?" asked the doctor, laughing. "Is there an oil-well on this island?"

"Not exactly an oil-well," answered Erik, "but what will answer our purpose nearly as well, multitudes of fat walruses. I wish to try an experiment, since we have one furnace especially adapted for burning oil."

They began their labors by performing the last rites of the two dead men. They tied weights to their feet and lowered them into the sea. Then the "Alaska" made fast to the ice bank in such a manner as to follow its movements without sustaining any injury to herself. They were able, with care, to carry on board again the provisions which they had landed, and which it was important for them not to lose. That operation accomplished, they devoted all their energies to the pursuit of the walrus.

Two or three times a day, parties armed with guns and harpoons and accompanied by all their Greenland dogs landed on the ice bank, and surrounded the sleeping monsters at the mouth of their holes. They killed them by firing a ball into their ears, then they cut them up, and placed the lard with which they were filled in their sleighs, and the dogs drew it to the "Alaska." Their hunting was so easy and so productive, that in eight days they had all the lard that they could carry. The "Alaska," still towed by the floating island, was now in the seventy-fourth degree; that is to say, she had passed Nova Zembla.

The ice island was now reduced at least one-half, and cracked by the sun was full of fissures, more or less extensive, evidently ready to go to pieces. Erik resolved not to wait until this happened, and ordering their anchor to be lifted, he sailed away westward.

The lard was immediately utilized in the fire of the "Alaska," and proved an excellent combustible. The only fault was that it choked up the chimney, which necessitated a daily cleaning. As for its odor, that would doubtless have been very disagreeable to southern passengers, but to a crew composed of Swedes and Norwegians, it was only a secondary inconvenience.

Thanks to this supply, the "Alaska" was able to keep up steam during the whole of the remainder of her voyage. She proceeded rapidly, in spite of contrary winds, and arrived on the 5th of September in sight of Cape North or Norway. They pursued their route with all possible speed, turned the Scandinavian Peninsula, repassed Skager-Rack, and reached the spot from which they had taken their departure.

On the 14th of September they cast anchor before Stockholm, which they had left on the tenth of the preceding February.

Thus, in seven months and four days, the first circumpolar periplus ............
