There was still, however, some light, and the Lieutenant struck his flint, and consulted his compass, passing a piece of burning touchwood over it, and then, drawing his cloak more closely around him, he plunged after the Sergeant across the unprotected plain.

At the first step, both were flung violently to the ground, but they managed to scramble up, and clinging to each other with their backs bent like two old crippled peasants, they struck into a kind of ambling trot.

There was a kind of awful grandeur in the storm to which neither was insensible. Jagged masses of mist and ragged rain-clouds swept along the ground. The loose earth and sand were whirled into the air and flung down again like grape-shot, and the lips of Hobson and his companion were wet with salt spray, although the sea was two or three miles distant at least.

During the rare brief pauses in the gale, they stopped and took breath, whilst the Lieutenant ascertained their position as accurately as possible.

The tempest increased as the night advanced, the air and water seemed to be absolutely confounded together, and low down on the horizon was formed one of those fearful waterspouts which can overthrow houses, tear up forests, and which the vessels whose safety they threaten attack with artillery. It really seemed as if the ocean itself was being torn from its bed and flung over the devoted little island.

Hobson could not help wondering how it was that the ice-field which supported it was not broken in a hundred places in this violent convulsion of the sea, the roaring of which could be distinctly heard where he stood. Presently Long, who was a few steps in advance, stopped suddenly, and turning round managed to make the Lieutenant hear the broken words-

"Not that way!"

"Why not?"

"The sea!"

"What, the sea! We cannot possibly have got to the southeast coast!"

"Look, look, Lieutenant!"

It was true, a vast sheet of water was indistinctly visible before them, and large waves were rolling up and breaking at the Lieutenant's feet.

Hobson again had recourse to his flint, and with the aid of some lighted touchwood consulted the needle of his compass very carefully.

"No," he said, "the sea is farther to the left, we have not yet passed the wood between us and Cape Michael."

"Then it is"--

"It is a fracture of the island!" cried Hobson, as both were compelled to fling themselves to the ground before the wind, "either a large portion of our land has been broken off and drifted away, or a gulf has been made, which we can go round. Forwards!"

They struggled to their feet and turned to the right towards the centre of the island. For about ten minutes they pressed on in silence, fearing, not without reason, that all communication with the south of the island would be found to be cut off. Presently, however, they no longer heard the noise of the breakers.

"It is only a gulf." screamed Hobson in the Sergeant's ear. "Let us turn round."

And they resumed their original direction towards the south, but both knew only too well that they had a fearful danger to face, for that portion of the island on which they were was evidently cracked for a long distance, and might at any moment separate entirely; should it do so under the influence of the waves, they would inevitably be drifted away, whither they knew not. Yet they did not hesitate, but plunged into the mist, not even pausing to wonder if they should ever get back.

What anxious forebodings must, however, have pressed upon the heart of the Lieutenant. Could he now hope that the island would hold together until the winter? had not the inevitable breaking up already commenced? If the wind should not drive them on to the coast, were they not doomed to perish very soon, to be swallowed up by the deep, leaving no trace behind them? What a fearful prospect for all the unconscious inhabitants of the fort!

But through it all the two men, upheld by the consciousness of a duty to perform, bravely struggled on against the gale, which nearly tore them to pieces, along the new beach, the foam sometimes bathing their feet, and presently gained the large wood which shut in Cape Michael.
