THE breeze was scarcely perceptible; but what there was came from the west-a disagreeable habit of the winds during the equinoxes.
The rising sea varies much in its effects upon the Douvres rocks, depending upon the quarter of the wind.
According to the gale which drives them before it, the waves enter the rocky corridor either from the east or from the west. Entering from the east, the sea is comparatively gentle; coming from the west, it is always furious. The reason of this is, that the wind from the east blowing from the land has not had time to gather force; while the westerly winds, coming from the Atlantic, blow unchecked from a vast ocean. Even a every slight breeze, if it comes from the west, is serious. It rolls the huge billows from the illimitable space and dashes the waves against the narrow defile in greater bulk than can find entrance there.
A sea which rolls into a gulf is always terrible. It is the same with a crowd of people: a multitude is a sort of fluid body. When the quantity which can enter is less than the quantity endeavouring to force a way, there is a fatal crush among the crowd, a fierce convulsion on the water. As long as the west wind blows, however slight the breeze, the Douvres are twice a day subjected to that rude assault. The sea rises, the tide breasts up, the narrow gullet gives little entrance, the waves, driven against it violently, rebound and roar, and a tremendous surf beats the two sides of the gorge. Thus the Douvres, during the slightest wind from the west, present the singular spectacle of a sea comparatively calm without, while within the rocks a storm is raging. This tumult of waters, altogether confined and circumscribed, has nothing of the character of a tempest. It is a mere local outbreak among the waves, but a terrible one. As regards the winds from the north and south, they strike the rocks crosswise, and cause little surf in the passage. The entrance by the east, a fact which must be borne in mind, was close to "The Man" rock. The dangerous opening to the west was at the opposite extremity, exactly between the two Douvres.
It was at this western entrance that Gilliatt found himself with the wrecked Durande, and the sloop made fast beneath it.
A catastrophe seemed inevitable. There was not much wind, but it was sufficient for the impending mischief.
Before many hours the swell which was rising would be rushing with full force into the gorge of the Douvres. The first waves were already breaking. This swell, and eddy of the entire Atlantic, would have behind it the immense sea. There would be no squall; no violence, but a simple overwhelming wave, which, commencing on the coasts of America, rolls towards the shores of Europe with an impetus gathered over two thousand leagues. This wave, a gigantic ocean barrier, meeting the gap of the rocks, must be caught between the two Douvres, standing like watch-towers at the entrance, or like pillars of the defile. Thus swelled by the tide, augmented by resistance, driven back by the shoals, and urged on by the wind, it would strike the rock with violence, and with all the contortions from the obstacles it had encountered, and all the frenzy of a sea confined in limits, would rush between the rocky walls, where it would reach the sloop and the Durande, and, in all probability, destroy them.
A shield against this danger was wanting. Gilliatt had one.
The problem was to prevent the sea reaching it at one bound; to obstruct it from striking, while allowing it to rise; to bar the passage without refusing it admission; to prevent the compression of the water in the gorge, which was the whole danger; to turn an irruption into a simple flood; to extract, as it were, from the waves all their violence, and constrain the furies to be gentle: it was, in fact, to substitute an obstacle which will appease for an obstacle which irritates.
Gilliatt, with all that dexterity which he possessed, and which is so much more efficient than mere force, sprang upon the rocks like a chamois among the mountains or a monkey in the forest; using for his tottering and dizzy strides the smallest projecting stone; leaping into the water, and issuing from it again; swimming among the shoals and clambering the rocks, with a rope between his teeth and a mallet in his hand. Thus he detached the cable which kept suspended and also fast to the basement of the Little Douvre the end of the forward side of the Durande; fashioned out of some ends of hawsers a sort of hinges, holding this bulwark to the huge nails fixed in the granite; swung this apparatus of planks upon them, like the gates of a great dock, and turned their sides, as he would turn a rudder, outward to the waves, which pushed the extremities upon the Great Douvre, while the rope hinges detained the other extremities upon the Little Douvre. Next he contrived, by means of the huge nails placed beforehand for the purpose, to fix the same kind of fastenings upon the Great Douvre as on the little one; made completely fast the vast mass of wood-work against the two pillars of the gorge, slung a chain across this barrier like a baldric upon a cuirass; and in less than an hour this barricade against the sea was complete, and the gullet of the rocks closed as by a folding-door.
This powerful apparatus, a heavy mass of beams and planks which laid flat would have made a raft, and upright formed a wall, had by the aid of the water been handled by Gilliatt with the adroitness of a juggler. It might almost have been said that the obstruction was complete before the rising sea had the time to perceive it.
It was one of those occasions on which Jean Hart would have employed the famous expression which he applied to the sea every time he narrowly escaped shipwreck, "We have cheated the Englishman;" for it is well known that when that famous admiral meant to speak contemptuously of the ocean he called it "the English-man."
The entrance to the defile being thus protected, Gilliatt thought of the sloop. He loosened sufficient cable for the two anchors to allow her to rise with the tide; an operation similar to what the mariners of old called "mouiller avec des embossures." In all this Gilliatt was not taken the least by surprise; the necessity had been foreseen A seaman would have perceived it by the two pulleys of the top ropes cut in the form of snatch-blocks, and fixed behind the sloop, through which passed two ropes, the ends of which were slung through the rings of the anchors.
Meanwhile the tide was rising fast; the half flood had arrived-a moment when the shock of the waves, even in comparatively moderate weather, may become considerable. Exactly what Gilliatt expected came to pass. The waves rolled violently against the barrier, struck it, broke heavily and passed beneath. Outside was the heavy swell; within, the waters ran quietly. He had devised a sort of marine Furculę caudinę. The sea was conquered.
