In the middle of the night he awoke suddenly and with a jerk like the recoil of a spring.

He opened his eyes.

The Douvres, rising high over his head, were lighted up as by the white glow of burning embers. Over all the dark escarpment of the rock there was a light like the reflection of a fire.

Where could this fire come from?

It was from the water.

The aspect of the sea was extraordinary.

The water seemed a-fire. As far as the eye could reach, among the reefs and beyond them, the sea ran with flame. The flame was not red; it had nothing in common with the grand living fires of volcanic craters or of great furnaces. There was no sparkling, no glare, no purple edges, no noise. Long trails of a pale tint simulated upon the water the folds of a winding-sheet. A trembling glow was spread over the waves. It was the spectre of a great fire, rather than the fire itself. It was in some degree like the glow of unearthly flames lighting the inside of a sepulchre. A burning darkness.

The night itself, dim, vast, and wide-diffused, was the fuel of that cold flame. It was a strange illumination issuing out of blindness. The shadows even formed part of that phantom-fire.

The sailors of the Channel are familiar with those indescribable phosphorescences, full of warning for the navigator. They are nowhere more surprising than in the "Great V," near Isigny.

By this light, surrounding objects lose their reality. A spectral glimmer renders them, as it were, transparent. Rocks become no more than outlines. Cables of anchors look like iron bars heated to a white heat. The nets of the fishermen beneath the water seem webs of fire. The half of the oar above the waves is dark as ebony, the rest in the sea like silver. The drops from the blades uplifted from the water fall in starry showers upon the sea. Every boat leaves a furrow behind it like a comet's tail. The sailors, wet and luminous, seem like men in flames. If you plunge a hand into the water, you withdraw it clothed in flame. The flame is dead, and is not felt. Your arm becomes a firebrand. You see the forms of things in the sea roll beneath the waves as in liquid fire. The foam twinkles. The fish are tongues of fire, or fragments of the forked lightning, moving in the depths.

The reflection of this brightness had passed over the closed eyelids of Gilliatt in the sloop. It was this that had awakened him.

His awakening was opportune.

The ebb tide had run out, and the waters were beginning to rise again. The funnel, which had become disengaged during his sleep, was about to enter again into the yawning hollow above it.

It was rising slowly.

A rise of another foot would have entangled it in the wreck again. A rise of one foot is equivalent to half-an-hour's tide. If he intended, therefore, to take advantage of that temporary deliverance once more within his reach, he had just half-an-hour before him.

He leaped to his feet.

Urgent as the situation was, he stood for a few moments meditative, contemplating the phosphorescence of the waves.

Gilliatt knew the sea in all its phases. Notwithstanding all her tricks, and often as he had suffered from her terrors, he had long been her companion. That mysterious entity which we call the ocean had nothing in its secret thoughts which he could not divine. Observation, meditation, and solitude, had given him a quick perception of coming changes, of wind, or cloud, or wave.

Gilliatt hastened to the top ropes and payed out some cable; then being no longer held fast by the anchors, he seized the boat-hook of the sloop, and pushed her towards the entrance to the gorge some fathoms from the Durande, and quite near to the breakwater. Here, as the Guernsey sailors say, it had _du rang_. In less than ten minutes the sloop was withdrawn from beneath the carcase of the wreck. There was no further danger of the funnel being caught in a trap. The tide might rise now.

And yet Gilliatt's manner was not that of one about to take his departure.

He stood considering the light upon the sea once more; but his thoughts were not of starting. He was thinking of how to fix the sloop again, and how to fix it more firmly than ever, though near to the exit from the defile.

Up to this time he had only used the two anchors of the sloop and had not yet employed the little anchor of the Durande, which he had found, as will be remembered, among the breakers. This anchor had been deposited by him in readiness for any emergency, in a corner of the sloop, with a quantity of hawsers, and blocks of top-ropes, and his cable, all furnished beforehand with large knots, which prevented its dragging. He now let go this third anchor, taking care to fasten the cable to a rope, one end of which was slung through the anchor ring, while the other was attached to the windlass of the sloop. In this manner he made a kind of triangular, triple anchorage, much stronger than the moorings with two anchors. All this indicated keen anxiety, and a redoubling of precautions. A sailor would have seen in this operation something similar to an anchorage in bad weather, when there is fear of a current which might carry the vessel under the wind.

The phosphorescence which he had been observing, and upon which his eye was now fixed once more, was threatening, but serviceable at the same time. But for it he would have been held fast locked in sleep, and deceived by the night. The strange appearance upon the sea had awakened him, and made things about him visible.

The light which it shed among the rocks was, indeed, ominous; but disquieting as it appeared to be to Gilliatt, it had served to show him the dangers of his position, and had rendered possible his operations in extricating the sloop. Henceforth, whenever he should be able to set sail, the vessel, with its freight of machinery, would be free.

And yet the idea of departing was further than ever from his mind. The sloop being fixed in its new position, he went in quest of the strongest chain which he had in his store-cavern, and attaching it to the nails driven into the two Douvres, he fortified from within with this chain the rampart of planks and beams, already protected from without by the cross chain. Far from opening the entrance to the defile, he made the barrier more complete.

The phosphorescence lighted him still, but it was diminishing. The day, however, was beginning to break.

Suddenly he paused to listen.
