Top held him up by his clothes; but a strong current seized him and drove him towards the north, and after half an hour of exertion, he sank, dragging Top with him into the depths. From that moment to the moment in which he recovered to find himself in the arms of his friends he remembered nothing.

"However," remarked Pencroft, "you must have been thrown on to the beach, and you must have had strength to walk here, since Neb found your footmarks!"

"Yes... of course replied the engineer, thoughtfully; "and you found no traces of human beings on this coast?"

"Not a trace," replied the reporter; "besides, if by chance you had met with some deliverer there, just in the nick of time, why should he have abandoned you after having saved you from the waves?"

"You are right, my dear Spilett. Tell me, Neb," added the engineer, turning to his servant, "it was not you who... you can't have had a moment of unconsciousness... during which no, that's absurd.... Do any of the footsteps still remain?" asked Harding.

"Yes, master, replied Neb; "here, at the entrance, at the back of the mound, in a place sheltered from the rain and wind. The storm has destroyed the others."

"Pencroft," said Cyrus Harding, "will you take my shoe and see if it fits exactly to the footprints?"

The sailor did as the engineer requested. While he and Herbert, guided by Neb, went to the place where the footprints were to be found, Cyrus remarked to the reporter,--

"It is a most extraordinary thing!"

"Perfectly inexplicable!" replied Gideon Spilett.

"But do not dwell upon it just now, my dear Spilett, we will talk about it by-and-by."

A moment after the others entered.

There was no doubt about it. The engineer's shoe fitted exactly to the footmarks. It was therefore Cyrus Harding who had left them on the sand.

"Come," said he, "I must have experienced this unconsciousness which I attributed to Neb. I must have walked like a somnambulist, without any knowledge of my steps, and Top must have guided me here, after having dragged me from the waves... Come, Top! Come, old dog!"

The magnificent animal bounded barking to his master, and caresses were lavished on him. It was agreed that there was no other way of accounting for the rescue of Cyrus Harding, and that Top deserved all the honor of the affair.

Towards twelve o'clock, Pencroft having asked the engineer if they could now remove him, Harding, instead of replying, and by an effort which exhibited the most energetic will, got up. But he was obliged to lean on the sailor, or he would have fallen.

"Well done!" cried Pencroft; "bring the captain's litter."

The litter was brought; the transverse branches had been covered with leaves and long grass. Harding was laid on it, and Pencroft, having taken his place at one end and Neb at the other, they started towards the coast. There was a distance of eight miles to be accomplished; but, as they could not go fast, and it would perhaps be necessary to stop frequently, they reckoned that it would take at least six hours to reach the Chimneys. The wind was still strong, but fortunately it did not rain. Although lying down, the engineer, leaning on his elbow, observed the coast, particularly inland. He did not speak, but he gazed; and, no doubt, the appearance of the country, with its inequalities of ground, its forests, its various productions, were impressed on his mind. However, after traveling for two hours, fatigue overcame him, and he slept.

At half-past five the little band arrived at the precipice, and a short time after at the Chimneys.

They stopped, and the litter was placed on the sand; Cyrus Harding was sleeping profoundly, and did not awake.

Pencroft, to his extreme surprise, found that the terrible storm had quite altered the aspect of the place. Important changes had occurred; great blocks of stone lay on the beach, which was also covered with a thick carpet of sea-weed, algae, and wrack. Evidently the sea, passing over the islet, had been carried right up to the foot of the enormous curtain of granite.
