"Well," continued Captain Nemo, "you heard my question? Do you know the history of Spain?"

"Very slightly," I answered.

"Well, here are learned men having to learn," said the captain. "Come, sit down, and I will tell you a curious episode in this history. Sir, listen well," said he; "this history will interest you on one side, for it will answer a question which doubtless you have not been able to solve."

"I listen, captain," said I, not knowing what my interlocutor was driving at, and asking myself if this incident was bearing on our projected flight.

"Sir, if you have no objection, we will go back to 1702. You cannot be ignorant that your king, Louis XIV, thinking that the gesture of a potentate was sufficient to bring the Pyrenees under his yoke, had imposed the Duke of Anjou, his grandson, on the Spaniards. This prince reigned more or less badly under the name of Philip V, and had a strong party against him abroad. Indeed, the preceding year, the royal houses of Holland, Austria, and England had concluded a treaty of alliance at the Hague, with the intention of plucking the crown of Spain from the head of Philip V, and placing it on that of an archduke to whom they prematurely gave the title of Charles III.

"Spain must resist this coalition; but she was almost entirely unprovided with either soldiers or sailors. However, money would not fail them, provided that their galleons, laden with gold and silver from America, once entered their ports. And about the end of 1702 they expected a rich convoy which France was escorting with a fleet of twenty-three vessels, commanded by Admiral Chateau-Renaud, for the ships of the coalition were already beating the Atlantic. This convoy was to go to Cadiz, but the admiral, hearing that an English fleet was cruising in those waters, resolved to make for a French port.

"The Spanish commanders of the convoy objected to this decision. They wanted to be taken to a Spanish port, and if not to Cadiz, into Vigo Bay, situated on the northwest coast of Spain, and which was not blocked.

"Admiral Chateau-Renaud had the rashness to obey this injunction, and the galleons entered Vigo Bay.

"Unfortunately, it formed an open road which could not be defended in any way. They must therefore hasten to unload the galleons before the arrival of the combined fleet; and time would not have failed them had not a miserable question of rivalry suddenly arisen.

"You are following the chain of events?" asked Captain Nemo.

"Perfectly," said I, not knowing the end proposed by this historical lesson.

"I will continue. This is what passed. The merchants of Cadiz had a privilege by which they had the right of receiving all merchandise coming from the West Indies. Now, to disembark these ingots at the port of Vigo was depriving them of their rights. They complained at Madrid, and obtained the consent of the weak-minded Philip that the convoy, without discharging its cargo, should remain sequestered in the roads of Vigo until the enemy had disappeared.

"But while coming to this decision, on the 22d of October, 1702, the English vessels arrived in Vigo Bay, when Admiral Chateau-Renaud, in spite of inferior forces, fought bravely. But seeing that the treasure must fall into the enemy's hands, he burned and scuttled every galleon, which went to the bottom with their immense riches."

Captain Nemo stopped. I admit I could not yet see why this history should interest me.

"Well?" I asked.

"Well, M. Aronnax," replied Captain Nemo, "we are in that Vigo Bay; and it rests with yourself whether you will penetrate its mysteries."

The captain rose, telling me to follow him. I had had time to recover. I obeyed. The saloon was dark, but through the transparent glass the waves were sparkling. I looked.

For half a mile around the Nautilus the waters seemed bathed in electric light. The sandy bottom was clean and bright. Some of the ship's crew in their diving-dresses were clearing away half-rotten barrels and empty cases from the midst of the blackened wrecks. From these cases and from these barrels escaped ingots of gold and silver, cascades of piastres and jewels. The sand was heaped up with them. Laden with their precious booty the men returned to the Nautilus, disposed of their burden, and went back to this inexhaustible fishery of gold and silver.

I understood now. This was the scene of the battle of the 22d of October, 1702. Here on this very spot the galleons laden for the Spanish government had sunk. Here Captain Nemo came, according to his wants, to pack up those millions with which he burdened the Nautilus. It was for him and him alone America had given up her precious metals. He was heir direct, without anyone to share in those treasures torn from the Incas and from the conquered of Ferdinand Cortez.

"Did you know, sir," he asked, smiling, "that the sea contained such riches?"

"I knew," I answered, "that they value the money held in suspension in these waters at two millions."

"Doubtless; but to extract this money the expense would be greater than the profit. Here, on the contrary, I have but to pick up what man has lost; and not only in Vigo Bay, but in a thousand other spots where shipwrecks have happened, and which are marked on my submarine map. Can you understand now the source of the millions I am worth?"

"I understand, captain. But allow me to tell you that in exploring Vigo Bay you have only been beforehand with a rival society."

"And which?"

"A society which has received from the Spanish government the privilege of seeking these buried galleons. The shareholders are led on by the allurement of an enormous bounty, for they value these rich shipwrecks at five hundred millions."

"Five hundred millions they were," answered Captain Nemo, "but they are so no longer."

"Just so," said I; "and a warning to those shareholders would be an act of charity. But who knows if it would be well received? What gamblers usually regret above all is less the loss of their money, than of their foolish hopes. After all, I pity them less than the thousands of unfortunates to whom so much riches well distributed would have been profitable, while for them they will be forever barren."

I had no sooner expressed this regret than I felt that it must have wounded Captain Nemo.

"Barren!" he exclaimed, with animation. "Do you think then, sir, that these riches are lost because I gather them? Is it for myself alone, according to your idea, that I take the trouble to collect these treasures? Who told you that I did not make a good use of it? Do you think I am ignorant that there are suffering beings and oppressed races on this earth, miserable creatures to console, victims to avenge? Do you not understand?"

Captain Nemo stopped at these last words, regretting perhaps that he had spoken so much. But I had guessed that, whatever the motive which had forced him to seek independence under the sea, it had left him still a man, that his heart still beat for the sufferings of humanity, and that his immense charity was for oppressed races as well as individuals. And I then understood for whom those millions were destined, which were forwarded by Captain Nemo when the Nautilus was cruising in the waters of Crete.
