“At any rate we have a favorable wind for reaching Cape Mandible,” observed the reporter.

“A very fine wind,” replied the sailor; “but we must tack to enter the gulf, and I should like to see my way clear in these unknown quarters.”

“Quarters which appear to be filled with rocks,” added Herbert, “if we judge by what we saw on the south coast of Shark Gulf.”

“Pencroft,” said Cyrus Harding, “do as you think best, we will leave it to you.”

“Don’t make your mind uneasy, captain,” replied the sailor, “I shall not expose myself needlessly!  I would rather a knife were run into my ribs than a sharp rock into those of my ‘Bonadventure!’”

That which Pencroft called ribs was the pan of his vessel under water, and he valued it more than his own skin.

“What o’clock is it?” asked Pencroft.

“Ten o’clock,” replied Gideon Spilett.

“And what distance is it to the Cape, captain?”

“About fifteen miles,” replied the engineer.

“That’s a matter of two hours and a half,” said the sailor, “and we shall be off the Cape between twelve and one o’clock.  Unluckily, the tide will be turning at that moment, and will be ebbing out of the gulf.  I am afraid that it will be very difficult to get in, having both wind and tide against us.”

“And the more so that it is a full moon to-day,” remarked Herbert, “and these April tides are very strong.”

“Well, Pencroft,” asked Harding, “can you not anchor off the Cape?”

“Anchor near land, with bad weather coming on!” exclaimed the sailor.  “What are you thinking of, captain?  We should run aground, of a certainty!”

“What will you do then?”

“I shall try to keep in the offing until the flood, that is to say, till about seven in the evening, and if there is still light enough I will try to enter the gulf; if not, we must stand off and on during the night, and we will enter to-morrow at sunrise.”

“As I told you, Pencroft, we will leave it to you,” answered Harding.

“Ah!” said Pencroft, “if there was only a lighthouse on the coast, it would be much more convenient for sailors.”

“Yes,” replied Herbert, “and this time we shall have no obliging engineer to light a fire to guide us into port!”

“Why, indeed, my dear Cyrus,” said Spilett, “we have never thanked you; but frankly, without that fire we should never have been able—­”

“A fire?” asked Harding, much astonished at the reporter’s words.

“We mean, captain,” answered Pencroft, “that on board the ‘Bonadventure’ we were very anxious during the few hours before our return, and we should have passed to windward of the island, if it had not been for the precaution you took of lighting a fire the night of the 19th of October, on Prospect Heights.”

“Yes, yes!  That was a lucky idea of mine!” replied the engineer.

“And this time,” continued the sailor. “unless the idea occurs to Ayrton, there will be no one to do us that little service!”
