“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!” “No! No one!” answered Cyrus Harding. A few minutes after, finding himself alone in the bows of the vessel, with the reporter, the engineer bent down and whispered,-- “If there is one thing certain in this world, Spilett, it is that I never lighted any fire during the night of the 19th of October, neither on Prospect Heights nor on any other part of the island!” Chapter 20 Things happened as Pencroft had predicted, he being seldom mistaken in his prognostications. The wind rose, and from a fresh breeze it soon increased to a regular gale; that is to say, it acquired a speed of from forty to forty-five miles an hour, before which a ship in the open sea would have run under close-reefed topsails. Now, as it was nearly six o’clock when the “Bonadventure” reached the gulf, and as at that moment the tide turned, it was impossible to enter. They were therefore compelled to stand off, for even if he had wished to do so, Pencroft could not have gained the mouth of the Mercy. Hoisting the jib to the mainmast by way of a storm-sail, he hove to, putting the head of the vessel towards the land. Fortunately, although the wind was strong the sea, being sheltered by the land, did not run very high. They had then little to fear from the waves, which always endanger small craft. The “Bonadventure” would doubtlessly not have capsized, for she was well ballasted, but enormous masses of water falling on the deck might injure her if her timbers could not sustain them. Pencroft, as a good sailor, was prepared for anything. Certainly, he had great confidence in his vessel, but nevertheless he awaited the return of day with some anxiety.
