Suddenly the electric light went out; and at the same time they heard, in the distance, a strange thunder-clap, curiously different from the usual sound of thunder. It was repeated, with a less strident din, accompanied by a subterranean rattling; and then, growing noisier again, it burst a second time in a series of frightful detonations, louder than the roar of artillery. Then there was a frantic rush for the road. But the fugitives had not left the garden when the frightful catastrophe, announced by so many manifestations, occurred. The earth leapt beneath their feet and instantly fell away and leapt again like an animal in convulsions. Simon and his father were thrown against each other and then violently torn apart and hurled to the ground. All around them was the stupendous uproar of a tottering world in which everything was collapsing into an incredible chaos. The darkness seemed to have grown denser than ever. And then, suddenly, there was a less distant sound, a sound which touched them, so to speak, a sort of cracking noise. And shrieks rose into the air from the very bowels of the earth. "Stop!" cried Simon, catching hold of his father, whom he had succeeded in rejoining. "Stop!" He felt before him, at a distance of a few inches, the utter horror of a gaping abyss; and it was from the bottom of the abyss that the shrieks and howls of their companions rose. And there were three more shocks. . . . Simon realized a moment later that his father, clutching his arm, was dragging him away with fierce energy. Both were clambering up the road at a run, groping their way like blind men through the obstacles with which the earthquake had covered it. M. Dubosc had a goal in view, the Caude-Côte cliff, a bare plateau where they would be in absolute safety. But, on taking a cross-road, they struck against a band of maddened creatures who told them that the cliff had fallen, carrying numerous victims with it. All that these people could think of now was to run to the seashore. With them, M. Dubosc and his son stumbled down the paths which led to the valley of Pourville, whose beach lies in a cove some two miles from Dieppe. The front was obstructed by a crowd of villagers, while others were taking shelter from the rain behind the bathing-huts overturned by the wind. Others again, as the tide was very low, had gone down the sloping shingle and crossed the sands and ventured out to the rocks, as though the danger had ended there and there only. By the uncertain light of a moon which strove to pierce the curtain of the clouds, they could be seen wandering to and fro like ghosts. "Come, Simon!" said M. Dubosc. "Let's go over there. . . ." But Simon held him back: "We are all right here, father. Besides, it seems to be calming down. Take a rest." "Yes, yes, if you like," replied M. Dubosc, who was in a greatly dejected mood. "And then we will go back to Dieppe. I want to make sure that my boats have not been knocked about too much."
