"That is," rejoined Pencroft, "it is not more dangerous than a hare!" "And now," said Gideon Spilett, "since the jaguar has left its abode, I do not see, my friends, why we should not take possession of it for the night." "But others may come," said Pencroft. "It will be enough to light a fire at the entrance of the cavern," said the reporter, "and no wild beasts will dare to cross the threshold." "Into the jaguar's house, then!" replied the sailor, dragging after him the body of the animal. Whilst Neb skinned the jaguar, his companions collected an abundant supply of dry wood from the forest, which they heaped up at the cave. Cyrus Harding, seeing the clump of bamboos, cut a quantity, which he mingled with the other fuel. This done, they entered the grotto, of which the floor was strewn with bones, the guns were carefully loaded, in case of a sudden attack, they had supper, and then just before they lay down to rest, the heap of wood piled at the entrance was set fire to. Immediately, a regular explosion, or rather, a series of reports, broke the silence! The noise was caused, by the bamboos, which, as the flames reached them, exploded like fireworks. The noise was enough to terrify even the boldest of wild beasts. It was not the engineer who had invented this way of causing loud explosions, for, according to Marco Polo, the Tartars have employed it for many centuries to drive away from their encampments the formidable wild beasts of Central Asia. CHAPTER V Proposal to return by the Southern Shore -- Configuration of the Coast -- Searching for the supposed Wreck -- A Wreck in the Air -- Discovery of a small Natural Port -- At Midnight on the Banks of the Mercy -- The Canoe Adrift. Cyrus Harding and his companions slept like innocent marmots in the cave which the jaguar had so politely left at their disposal. At sunrise all were on the shore at the extremity of the promontory, and their gaze was directed towards the horizon, of which two-thirds of the circumference were visible. For the last time the engineer could ascertain that not a sail nor the wreck of a ship was on the sea, and even with the telescope nothing suspicious could be discovered. There was nothing either on the shore, at least, in the straight line of three miles which formed the south side of the promontory, for beyond that, rising ground hid the rest of the coast, and even from the extremity of the Serpentine Peninsula Cape Claw could not be seen. The southern coast of the island still remained to be explored. Now should they undertake it immediately, and devote this day to it?
