All approached, and saw to their extreme surprise, a boat floating down the current.
"Boat ahoy!" shouted the sailor, without thinking that perhaps it would be best to keep silence.
No reply. The boat still drifted onwards, and it was not more than twelve feet off, when the sailor exclaimed —
"But it is our own boat! she has broken her moorings, and floated down the current. I must say she has arrived very opportunely."
"Our boat?" murmured the engineer.
Pencroft was right. It was indeed the canoe, of which the rope had undoubtedly broken, and which had come alone from the sources of the Mercy. It was very important to seize it before the rapid current should have swept it away out of the mouth of the river, but Neb and Pencroft cleverly managed this by means of a long pole.
The canoe touched the shore. The engineer leapt in first, and found, on examining the rope, that it had been really worn through by rubbing against the rocks.
"Well," said the reporter to him, in a low voice, "this is a strange thing."
"Strange indeed!" returned Cyrus Handing.
Strange or not, it was very fortunate. Herbert, the reporter, Neb, and Pencroft, embarked in turn. There was no doubt about the rope having been worn through, but the astonishing part of the affair was, that the boat should have arrived just at the moment when the settlers were there to seize it on its way, for a quarter of an hour earlier or later it would have been lost in the sea.
If they had been living in the time of genii, this incident would have given them the right to think that the island was haunted by some supernatural being, who used his power in the service of the castaways!
A few strokes of the oar brought the settlers to the mouth of the Mercy. The canoe was hauled up on the beach near the Chimneys, and all proceeded towards the ladder of Granite House.
But at that moment, Top barked angrily, and Neb, who was looking for the first steps, uttered a cry.
There was no longer a ladder!

Cyrus Harding stood still, without saying a word. His companions searched in the darkness on the wall, in case the wind should have moved the ladder, and on the ground, thinking that it might have fallen down… But the ladder had quite disappeared. As to ascertaining if a squall had blown it on to the landing-place, half way up, that was impossible in the dark.
