"Good God! Sergeant!" exclaimed Mrs Barnett; "what has happened?"

"Nothing," replied Long, shaking himself like a wet spaniel, "except that the ice gave way under me, and I took a compulsory bath."

"You forgot what I told you about not digging too deeply, then," said Hobson.

"Beg pardon, sir; I hadn't cut through fifteen inches of the ice, and I expect there was a kind of cavern where I was working-the ice did not touch the water. It was just like going through a ceiling. If I hadn't been able to hang on by my knife, I should have slipped under the island like a fool, and that would have been a pity, wouldn't it, madam?"

"A very great pity, my brave fellow," said Mrs Barnett, pressing his hand.

Long's explanation was correct; for some reason or another-most likely from an accumulation of air-the ice had formed a kind of vault above the water, and of course it soon gave way under the weight of the Sergeant and the blows of his chisel.

The same thing might happen in other parts of the island, which was anything but reassuring. Where could they be certain of treading on firm ground? Might not the earth give way beneath their feet at any minute? What heart, however brave, would not have sunk at the thought of the thin partition between them and the awful gulf of the ocean?

Sergeant Long, however, thought but little of his bath, and was ready to begin mining in some other place. This Mrs Barnett would not allow. A night in the open air would do her no harm; the shelter of the coppice near would be protection enough for them all; and Sergeant Long was obliged to submit.

The camp was, therefore, moved back some thirty yards from the beach, to a rising ground on which grew a few clumps of pines and willows which could scarcely be called a wood. Towards ten o'clock the disc of the sun began to dip below the horizon, and before it disappeared for the few hours of the night a crackling fire of dead branches was blazing at the camp.

Long had now a fine opportunity of drying his legs, of which he gladly availed himself. He and Hobson talked together earnestly until twilight set in, and Mrs Barnett occasionally joined in the conversation, doing the best she could to cheer the disheartened Lieutenant. The sky was bright with stars, and the holy influence of the night could not fail to calm his troubled spirit. The wind murmured softly amongst the pines; even the sea appeared to be wrapt in slumber, its bosom slightly heaving with the swell, which died away upon the beach with a faint rippling sound. All creation was hushed, not even the wail of a sea bird broke upon the ear, the crisp crackling of the dead branches was exchanged for a steady flame, and nothing but the voices of the wanderers broke the sublime, the awful silence of the night.

"Who would imagine," said Mrs Barnett, "that we were floating on the surface of the ocean! It really requires an effort to realise it, for the sea which is carrying us along in its fatal grasp appears to be absolutely motionless!"

"Yes, madam," replied Hobson;" and if the floor of our carriage were solid, if I did not know that sooner or later the keel of our boat will be missing, that some day its hull will burst open, and finally, if I knew where we are going, I should rather enjoy floating on the ocean like this."

"Well, Lieutenant," rejoined Mrs Barnett, "could there be a pleasanter mode of travelling than ours? We feel no motion. Our island has exactly the same speed as the current which is bearing it away. Is it not like a balloon voyage in the air? What could be more delightful than advancing with one's house, garden, park, &c.? A wandering island, with a solid insubmersible foundation, would really be the most comfortable and wonderful conveyance that could possibly be imagined. I have heard of hanging gardens. Perhaps some day floating parks will be invented which will carry us all over the globe! Their size will render them insensible to the action of the waves, they will have nothing to fear from storms, and perhaps with a favourable wind they might be guided by means of immense sails! What marvels of vegetation would be spread before the eyes of the passengers when they passed from temperate to torrid zones! With skilful pilots, well acquainted with the currents, it might be possible to remain in one latitude, and enjoy a perpetual spring."

Hobson could not help smiling at Mrs Barnett's fancies.
