Some slight repairs were required in the engine-room, so the Arrandoon lay here for a week.

“To think,” said McBain, as he stood on the bridge one day with our heroes, “that in the far-distant past that lonely isle of gloom was once clad in all the bright colour of tropical vegetation, with wild beasts roaming in its jungles and forests, and wild birds filling its groves with music,—an island of sunshine, flowers, and beauty! And now behold it.”

An expedition was got up to explore the isle, and to climb its highest peak to make observations.

McBain himself accompanied it, so did Allan, Rory, and Seth. It was no easy task, climbing that snowy cone by the light of stars and Aurora. But they gained the summit ere the short, short day broke.

To the north and west they saw land and mountains, stretching away and away as far as eye could follow them. To the east and north water studded with ugly icebergs that looked as if they had broken away from the shores of the western land.

“But what is that in the middle of yonder ice-floe to the south and west?” cried Rory.

“As I live,” exclaimed McBain, as he eyed the object through the glass, “it is a ship of some kind, evidently deserted; and it is quite as evident that we are not the only explorers that have reached as far north as this island.”

The mystery was explained next day, and a sad story brought to light. McBain and party landed on the floe and walked towards the derelict. She was sloop-rigged, with sails all clewed, and her hull half hidden in snow. After a deal of difficulty they succeeded in opening one of the companion hatches, and making their way down below.

No less than five unburied corpses lay huddled together in the little cabin. From their surroundings it was plain they had been walrus-hunters, and it was not difficult to perceive that the poor fellows had died from cold and hunger many, many years before.

Frozen in, too far up in this northern sea, they had been unable to regain the open water, and so had miserably perished.
