to seek on the south what they had not been able to find on the west.
Gideon Spilett proposed to continue the exploration, that the question of the supposed wreck might be completely settled, and he asked at what distance Claw Cape might be from the extremity of the peninsula.
"About thirty miles," replied the engineer, "if we take into consideration the curvings of the coast."
"Thirty miles!" returned Spilett. "That would be a long day's march. Nevertheless, I think that we should return to Granite House by the south coast."
"But," observed Herbert, "from Claw Cape to Granite House there must be at least another ten miles."
"Make it forty miles in all," replied the engineer, "and do not hesitate to do it. At least we should survey the unknown shore, and then we shall not have to begin the exploration again."
"Very good," said Pencroft. "But the boat?"
"The boat has remained by itself for one day at the sources of the Mercy," replied Gideon Spilett; "it may just as well stay there two days! As yet, we have had no reason to think that the island is infested by thieves!"
"Yet," said the sailor, "when I remember the history of the turtle, I am far from confident of that."
"The turtle! the turtle!" replied the reporter. "Don't you know that the sea turned it over?"
"Who knows?" murmured the engineer.
"But———" began Neb. He had evidently something to say, for he opened his mouth to speak and yet said nothing.
"What do you want to say, Neb?" asked the engineer.
"If we return by the shore to Claw Cape," replied Neb, "after having doubled the Cape, we shall be stopped———"
"By the Mercy! of course," replied Herbert, "and we shall have neither bridge nor boat by which to cross."
"But, captain," added Pencroft, "with a few floating trunks we shall have no difficulty in crossing the river."
"Never mind," said Spilett, "it will be useful to construct a bridge so we can have easy access to the Far West!"
"A bridge!" cried Pencroft. "Well, is not the captain the best engineer in his profession? He will make us a bridge when we want one. As to transporting you this
