guided them surely. The engineer had supposed that the wire would perhaps stop at the bottom of the valley, and that the stranger's retreat would be there.
Nothing of the sort. They were obliged to ascend the southwestern spur, and re-descend on that arid plateau terminated by the strangely-wild basalt cliff. From time to time one of the colonists stooped down and felt for the wire with his hands; but there was now no doubt that the wire was running directly towards the sea. There, to a certainty, in the depths of those rocks, was the dwelling so long sought for in vain.
The sky was literally on fire. Flash succeeded flash. Several struck the summit of the volcano in the midst of the thick smoke. It appeared there as if the mountain was vomiting flame. At a few minutes to eleven the colonists arrived on the high cliff overlooking the ocean to the west. The wind had risen. The surf roared 500 feet below.
Harding calculated that they had gone a mile and a half from the corral. At this point the wire entered among the rocks, following the steep side of a narrow ravine. The settlers followed it at the risk of occasioning a fall of the slightly-balanced rocks, and being dashed into the sea. The descent was extremely perilous, but they did not think of the danger; they were no longer masters of themselves, and an irresistible attraction drew them towards this mysterious place as the magnet draws iron.
Thus they almost unconsciously descended this ravine, which even in broad daylight would have been considered impracticable. The stones rolled and sparkled like fiery balls when they crossed through the gleams of light. Harding was first—Ayrton last. On they went, step by step. Now they slid over the slippery rock; then they struggled to their feet and scrambled on.
At last the wire touched the rocks on the beach. The colonists had reached the bottom of the basalt cliff. There appeared a narrow ridge, running horizontally and parallel with the sea. The settlers followed the wire along it. They had not gone a hundred paces when the ridge by a moderate incline sloped down to the sea. The engineer seized the wire and found that it disappeared beneath the waves.
His companions were stupefied. A cry of disappoint-
