I should not like to meet one under the waves. A pearl has been called by poets a tear of the sea, and anything more lovely around a maiden"s neck cannot be conceived. I have a strong wish to hunt for those tears of the sea, and behold them growing in their sh.e.l.ls, but Heaven protect us from the sharks."
Stump disappeared for a brief s.p.a.ce, and returned with a long harpoon.
"What have you got there?" asked Mont.
"It"s a reg"lar pig-sticker, isn"t it, sir?" remarked Stump, regarding it admiringly.
"It does look as if it could give an ugly prod," remarked Carl.
"They call it a harpoon; thing for sticking whales. Me and Number One, that"s the n.i.g.g.e.r as waits on us, is friends, sir, and he"s given me this to fight the darned sharkses with."
"Bravo, Stump!" exclaimed Carl.
"It would be "Bravo Stump," if I could rip up an inch or two of that captain, and seize the blessed ship!" rejoined the boy with a scowl.
Mont said nothing in reply, but waited patiently for the signal which would summon him and his companions to the captain"s side.
It came an hour or two before daybreak.
A negro summoned them to the platform, near which the boat attached to the ship was riding.
It was manned by four men, and when all the party were on board the negroes began to row toward the island.
At six o"clock the day broke. They were a few miles from the land, which was distinctly visible, with a few trees scattered here and there.
The captain stood up in the boat, and narrowly regarded the sea. At last he gave a sign, and the anchor was lowered.
"Here we are," said the captain. "Put on your divers" caps, gentlemen, and follow me."
The heavy sea garments were quickly put on.
The electric lamps were not needed, because the depth was not great.
Besides, the electric light would attract the sharks, who were creatures they could not afford to despise.
The only arm given to each of the party was a long, sharp knife.
Captain Vindex set the example of springing into the sea, the others following him as soon as they were thoroughly equipped.
The negroes remained in the boat awaiting their return.
A depth of about three yards and a half did not give them a very great submersion.
To be supplied with condensed air, to be armed, and well lighted up by the sun was delightful. They walked along the bottom of the sea, easily seeing the smallest object on all sides of them.
After some little walking they came to several oyster banks, from which the sh.e.l.ls containing the valuable pearls were dragged by the hands of the divers.
There were millions of them, and the mine seemed inexhaustible.
They could not stop to examine everything, for it was necessary to follow the captain everywhere.
The road was uneven; sometimes Mont could raise his arm and put his hand out of the water; at others, he was descending a slope, and the sun"s rays were not so vivid.
Everything became more obscure, and great sh.e.l.ls were seen sticking to curiously shaped rocks.
After a time a large grotto appeared before them, dimly lighted.
The captain entered, followed by the rest of the party, the professor eagerly taking note of everything.
Stump carried his harpoon, which was a good deal longer than himself; and the two boys eagerly looked for pearls, as if they expected to find them lying at their feet.
Descending an inclined plane, Captain Vindex stopped and pointed out an object which they had not hitherto perceived.
It was an oyster of gigantic size.
Lying alone upon the granite rock, it took up a large s.p.a.ce, and never had the professor even heard of such a huge bivalve.
The sh.e.l.ls were open a little, as if the oyster was feeding, which enabled the captain to introduce his knife.
Keeping the two sh.e.l.ls open by both ends of his knife, he pushed back the flesh of the oyster and revealed a pearl as big as a small cocoanut.
It was a pearl worth at least a hundred thousand dollars.
CHAPTER XXV.
THE MAN OF MYSTERY.
Mont advanced to the oyster, and stretched out his hand as if he would have seized the pearl, but he was disappointed.
By a sudden movement the captain withdrew his knife, and the two sh.e.l.ls came together with a sharp snap.
Satisfied with showing them this treasure of the deep, he turned round, and retraced his steps, leaving the precious pearl behind them.
Incomprehensible man, he was now more than ever a mystery to our hero.
He allowed them to seek and take numerous other pearls, but would not let them touch that he had shown them.
Again they wandered along the bottom of the sea, beholding many things worthy of observation.
Sometimes the bank was so shallow that their heads came above the water; at others they sank several yards below.
Suddenly the captain stopped, and by a movement of his hand ordered the party to conceal themselves behind a projecting rock.
He pointed to the liquid ma.s.s in front of them, and all followed with their eyes the direction indicated.
