"Pay attention to my wishes," he continued. "The 'Nautilus' is imprisoned in this grotto, the entrance of which is blocked up; but, although egress is impossible, the vessel may at least sink in the abyss, and there bury my remains."

The colonists listened reverently to the words of the dying man.

"To-morrow, after my death, Mr. Harding," continued the captain, "yourself and companions will leave the 'Nautilus,' for all the treasures it contains must perish with me. One token alone will remain with you of Prince Dakkar, with whose history you are now acquainted. That coffer yonder contains diamonds of the value of many millions, most of them mementoes of the time when, husband and father, I thought happiness possible for me, and a collection of pearls gathered by my friends and myself in the depths of the ocean. Of this treasure at a future day, you may make good use. In the hands of such men as yourself and your comrades, Captain Harding, money will never be a source of danger. From on high I shall still participate in your enterprises, and I fear not but that they will prosper."

After a few moments' repose, necessitated by his extreme weakness, Captain Nemo continued,--

"To-morrow you will take the coffer, you will leave the saloon, of which you will close the door; then you will ascend on to the deck of the 'Nautilus,' and you will lower the mainhatch so as entirely to close the vessel."

"It shall be done, captain," answered Cyrus Harding.

"Good. You will then embark in the canoe which brought you hither; but, before leaving the 'Nautilus,' go to the stern and there open two large stop-cocks which you will find upon the water-line. The water will penetrate into the reservoirs, and the 'Nautilus' will gradually sink beneath the water to repose at the bottom of the abyss."

And comprehending a gesture of Cyrus Harding, the captain added,--

"Fear nothing! You will but bury a corpse!"

Neither Cyrus Harding nor his companions ventured to offer any observation to Captain Nemo. He had expressed his last wishes, and they had nothing to do but to conform to them.

"I have your promise, gentlemen?" added Captain Nemo.

"You have, captain," replied the engineer.

The captain thanked the colonists by a sign, and requested them to leave him for some hours. Gideon Spilett wished to remain near him, in the event of a crisis coming on, but the dying man refused, saying, "I shall live until to-morrow, sir."

All left the saloon, passed through the library and the dining-room, and arrived forward, in the machine-room where the electrical apparatus was established, which supplied not only heat and light, but the mechanical power of the "Nautilus."

The "Nautilus" was a masterpiece containing masterpieces with itself, and the engineer was struck with astonishment.

The colonists mounted the platform, which rose seven or eight feet above the water. There they beheld a thick glass lenticular covering, which protected a kind of large eye, from which flashed forth light. Behind this eye was apparently a cabin containing the wheels of the rudder, and in which was stationed the helmsman, when he navigated the "Nautilus" over the bed of the ocean, which the electric rays would evidently light up to a considerable distance.

Cyrus Harding and his companions remained for a time silent, for they were vividly impressed by what they had just seen and heard, and their hearts were deeply touched by the thought that he whose arm had so often aided them, the protector whom they had known but a few hours, was at the point of death.

Whatever might be the judgment pronounced by posterity upon the events of this, so to speak, extra-human existence, the character of Prince Dakkar would ever remain as one of those whose memory time can never efface.

"What a man!" said Pencroft. "Is it possible that he can have lived at the bottom of the sea? And it seems to me that perhaps he has not found peace there any more than elsewhere!"

"The 'Nautilus,'" observed Ayrton, "might have enabled us to leave Lincoln Island and reach some inhabited country."

"Good Heavens!" exclaimed Pencroft, "I for one would never risk myself in such a craft.
