Conseil could not believe his eyes, and questioned me as to the cause of this strange phenomenon. Happily I was able to answer him.

“It is called a milk sea,” I explained. “A large extent of white wavelets often to be seen on the coasts of Amboyna, and in these parts of the sea.”

“But, sir,” said Conseil, “can you tell me what causes such an effect? for I suppose the water is not really turned into milk.”

“No, my boy; and the whiteness which surprises you is caused only by the presence of myriads of infusoria, a sort of luminous little worm, gelatinous and without colour, of the thickness of a hair, and whose length is not more than seven-thousandths of an inch. These insects adhere to one another sometimes for several leagues.”

“Several leagues!” exclaimed Conseil.

“Yes, my boy; and you need not try to compute the number of these infusoria. You will not be able, for, if I am not mistaken, ships have floated on these milk seas for more than forty miles.”

Towards midnight the sea suddenly resumed its usual colour; but behind us, even to the limits of the horizon, the sky reflected the whitened waves, and for a long time seemed impregnated with the vague glimmerings of an aurora borealis.

On the 28th of February, when at noon the Nautilus came to the surface of the sea, in 9° 4’ N. lat., there was land in sight about eight miles to westward. The first thing I noticed was a range of mountains about two thousand feet high, the shapes of which were most capricious. On taking the bearings, I knew that we were nearing the island of Ceylon, the pearl which hangs from the lobe of the Indian Peninsula.

Captain Nemo and his second appeared at this moment. The Captain glanced at the map. Then turning to me, said:

“The Island of Ceylon, noted for its pearl-fisheries. Would you like to visit one of them, M. Aronnax?”

“Certainly, Captain.”

“Well, the thing is easy. Though, if we see the fisheries, we shall not see the fishermen. The annual exportation has not yet begun. Never mind, I will give orders to make for the Gulf of Manaar, where we shall arrive in the night.”

The Captain said something to his second, who immediately went out. Soon the Nautilus returned to her native element, and the manometer showed that she was about thirty feet deep.

“Well, sir,” said Captain Nemo, “you and your companions shall visit the Bank of Manaar, and if by chance some fisherman should be there, we shall see him at work.”

“Agreed, Captain!”

“By the bye, M. Aronnax you are not afraid of sharks?”

“Sharks!” exclaimed I.

This question seemed a very hard one.

“Well?” continued Captain Nemo.

“I admit, Captain, that I am not yet very familiar with that kind of fish.”

“We are accustomed to them,” replied Captain Nemo, “and in time you will be too. However, we shall be armed, and on the road we may be able to hunt some of the tribe. It is interesting. So, till to-morrow, sir, and early.”
