"It has happened before, madam, it has happened before. Let me remind you of the great severity of last cold season; now it has been noticed that two long bitter winters seldom succeed each other, and the whalers of the northern seas know it well. A bitter winter when we should have been glad of a mild one, and a mild one when we so sorely need the reverse. It must be owned, we have been strangely unfortunate thus far! And when I think of six hundred miles to cross with women and a child!"...

And Hobson pointed to the vast white plain, with strange irregular markings like guipure work, stretching away into the infinite distance. Sad and desolate enough it looked, the imperfectly frozen surface cracking every now and then with an ominous sound. A pale moon, its light half quenched in the damp mists, rose but a few degrees above the gloomy horizon and shot a few faint beams upon the melancholy scene. The half-darkness and the refraction combined doubled the size of every object. Icebergs of moderate height assumed gigantic proportions, and were in some cases distorted into the forms of fabulous monsters. Birds passed overhead with loud flapping of wings, and in consequence of this optical illusion the smallest of them appeared as large as a condor or a vulture. In the midst of the icebergs yawned apparently huge black tunnels, into which the boldest man would scarcely dare to venture, and now and then sudden convulsions took place, as the icebergs, worn away at the base, heeled over with a crash, the sonorous echoes taking up the sounds and carrying them along. The rapid changes resembled the transformation scenes of fairyland, and terrible indeed must all those phenomena have appeared to the luckless colonists who were about to venture across the ice-field!

In spite of her moral and physical courage Mrs Barnett could not control an involuntary shudder. Soul and body alike shrunk from the awful prospect, and she was tempted to shut her eyes and stop her ears that she might see and hear no more. When the moon was for a moment veiled behind a heavy cloud, the gloom of the Polar landscape became still more awe-inspiring, and before her mind's eye rose a vision of the caravan of men and women struggling across these vast solitudes in the midst of hurricanes, snow-storms, avalanches, and in the thick darkness of the Arctic night!

Mrs Barnett, however, forced herself to look; she wished to accustom her eyes to these scenes, and to teach herself not to shrink from facing their terrors. But as she gazed a cry suddenly burst from her lips, and seizing Hobson's hand, she pointed to a huge object, of ill-defined dimensions, moving about in the uncertain light, scarcely a hundred paces from where they stood.

It was a white monster of immense size, more than a hundred feet high. It was pacing slowly along over the broken ice, bounding from one piece to another, and beating the air with its huge feet, between which it could have held ten large dogs at least. It, too, seemed to be seeking a practicable path across the ice-it, too, seemed anxious to fly from the doomed island. The ice gave way beneath its weight, and it had often considerable difficulty in regaining its feet.

The monster made its way thus for about a quarter of a mile across the ice, and then, its farther progress being barred, it turned round and advanced towards the spot where Mrs Barnett and the Lieutenant stood.

Hobson seized the gun which was slung over his shoulder and presented it at the animal, but almost immediately lowering the weapon, he said to Mrs Barnett-

"A bear, madam, only a bear, the size of which has been greatly magnified by refraction."

It was, in fact, a Polar bear, and Mrs Barnett drew a long breath of relief as she understood the optical illusion of which she had been the victim. Then an idea struck her.

"It is my bear!" she exclaimed, "the bear with the devotion of a Newfoundland dog! Probably the only one still on the island. But what is he doing here?"

"He is trying to get away," replied Hobson, shaking his head. "He is trying to escape from this doomed island, and he cannot do so! He is proving to us that we cannot pass where he has had to turn back!"

Hobson was right, the imprisoned animal had tried to leave the island and to get to the continent, and having failed it was returning to the coast.
