done, Harding lit the end of the sulphured fiber, and leaving the place, he returned with his companions to the Chimneys.

      The fiber was intended to burn five and twenty minutes, and, in fact, five and twenty minutes afterwards a most tremendous explosion was heard. The island appeared to tremble to its very foundation. Stones were projected in the air as if by the eruption of a volcano. The shock produced by the displacing of the air was such, that the rocks of the Chimneys shook. The settlers, although they were more than two miles from the mine, were thrown on the ground.

      They rose, climbed the plateau, and ran towards the place where the bank of the lake must have been shattered by the explosion.

      A cheer escaped them! A large rent was seen in the granite! A rapid stream of water rushed foaming across the plateau and dashed down a height of three hundred feet on to the beach!

      Cyrus Harding’s project had succeeded, but, according to his usual habit he showed no satisfaction; with closed lips and a fixed look, he remained motionless. Herbert was in ecstasies, Neb bounded with joy, Pencroft nodded his great head, murmuring these words,—

      “Come, our engineer gets on capitally!”

      The nitro–glycerine had indeed acted powerfully. The opening which it had made was so large that the volume of water which escaped through this new outlet was at least treble that which before passed through the old one. The result was, that a short time after the operation the level of the lake would be lowered two feet, or more.

      The settlers went to the Chimneys to take some pickaxes, iron–tipped spears, string made of fibers, flint and steel; they then returned to the plateau, Top accompanying them.

      On the way the sailor could not help saying to the engineer,—

      “Don’t you think, captain, that by means of that charming liquid you have made, one could blow up the whole of our island?”

      “Without any doubt, the island, continents, and the world itself,” replied the engineer. “It is only a question of quantity.”

      “Then could you not use this nitro–glycerine for loading firearms?” asked the sailor.

      “No, Pencroft; for it is too explosive a substance. But it would be easy to make some guncotton, or even ordinary powder, as we have azotic acid, saltpeter, sulphur, and coal. Unhappily, it is the guns which we have not got.”

      “Oh, captain,” replied the sailor, “with a little determination—”

      Pencroft had erased the word “impossible” from the dictionary of Lincoln Island.

      The settlers, having arrived at Prospect Heights, went immediately towards that point of the lake near which was the old opening now uncovered. This outlet had now become practicable, since the water no longer rushed through it, and it would doubtless be easy to explore the interior.

      In a few minutes the settlers had reached the lower point of the lake, and a glance showed them that the object had been attained.

      In fact, in the side of the lake, and now above the surface of the water, appeared the long–looked–for opening. A narrow ridge, left bare by the retreat of the water, allowed them to approach it. This orifice was nearly twenty feet in width, but scarcely two in height. It was like the mouth of a drain at the edge of the pavement, and therefore did not offer an easy passage to the settlers; but Neb and Pencroft, taking their pickaxes, soon made it of a suitable height.

      The engineer then approached, and found that the sides of the opening, in its upper part at least, had not a slope of more than from thirty to thirty–five degrees. It was therefore practicable, and, provided that the declivity did not increase, it would be easy to descend even to the level of the sea. If then, as was probable, some vast cavity existed in the interior of the granite, it might, perhaps, be of great use.

      “Well, captain, what are we stopping for?” asked the sailor, impatient to enter the narrow passage. “You see Top has got before us!”

      “Very well,” replied the engineer. “But we must see our way. Neb, go and cut some resinous branches.”

      Neb and Herbert ran to the edge of the lake, shaded with pines and other green trees, and soon returned with some branches, which they made into torches. The torches were lighted with flint and steel, and Cyrus Harding leading, the settlers ventured into the dark passage, which the overplus of the lake had formerly filled.

      Contrary to what might have been supposed, the diameter of the passage increased as the explorers proceeded, so that they very soon were able to stand upright. The granite, worn by the water for an infinite time, was very slippery, and falls were to be dreaded. But the settlers were all attached to each other by a cord, as is frequently done in ascending mountains. Happily some projections of the granite, forming regular steps, made the descent less perilous. Drops, still hanging from the rocks, shone here and there under the light of the torches, and the explorers guessed that the sides were clothed with innumerable stalactites. The engineer examined this black granite. There was not a stratum, not a break in it. The mass was compact, and of an extremely close grain. The passage dated, then, from the very origin of the island. It was not the water which little by little had hollowed it. Pluto and not Neptune had bored it with his own hand, and on the wall traces of an eruptive work could be distinguished, which all the washing of the water had not been able totally to efface.

      The settlers descended very slowly. They could not but feel a certain awe, in this venturing into these unknown depths, for the first time visited by human beings. They did not speak, but they thought; and the thought came to more than one, that some polypus or other gigantic cephalopod might inhabit the interior cavities, which were in communication with the sea. However, Top kept at the head of the little band, and they could rely on the sagacity of the dog, who would not fail to give the alarm if there was any need for it.

      After having descended about a hundred feet, following a winding road, Harding who was walking on before, stopped, and his companions came up with him. The place where they had halted was wider, so as to form a cavern of moderate dimensions. Drops of water fell from the vault, but that did not prove that they oozed through the rock. They were simply the last traces left by the torrent which had so long thundered through this cavity, and the air there was pure though slightly damp, but producing no mephitic exhalation.

      “Well, my dear Cyrus,” said Gideon Spilett, “here is a very secure retreat, well hid in the depths of the rock, but it is, however, uninhabitable.”

      “Why uninhabitable?” asked the sailor.

      “Because it is too small and too dark.”

      “Couldn’t we enlarge it, hollow it out, make openings to let in light and air?” replied Pencroft, who now thought nothing impossible.

      “Let us go on with our exploration,” said Cyrus Harding. “Perhaps lower down, nature will have spared us this labor.”

      “We have only gone a third of the way,” observed Herbert.

      “Nearly a third,” replied Harding, “for we have descended a hundred feet from the opening, and it is not impossible that a hundred feet farther down—”

      “Where is Top?” asked Neb, interrupting his master.

      They searched the cavern, but the dog was not there.

      “Most likely he has gone on,” said Pencroft.

      “Let us join him,” replied Harding.

      The descent was continued. The engineer carefully observed all the deviations
