What was his astonishment at seeing that there were four quite different kinds, some white, some red, some blue, and some yellow. He caught four, one of each colour. As he had never seen any like them he admired them very much, and he was very pleased to think how much money he would get for them.

"Take these fish and carry them to the Sultan, who will give you more money for them than you have ever had in your life. You can come every day to fish in this lake, but be careful not to throw your nets more than once every day, otherwise some harm will happen to you. If you follow my advice carefully you will find it good."

Saying these words, he struck his foot against the ground, which opened, and when he had disappeared, it closed immediately.

The fisherman resolved to obey the genius exactly, so he did not cast his nets a second time, but walked into the town to sell his fish at the palace.

When the Sultan saw the fish he was much astonished. He looked at them one after the other, and when he had admired them long enough, "Take these fish," he said to his first vizir, "and given them to the clever cook the Emperor of the Greeks sent me. I think they must be as good as they are beautiful."

The vizir took them himself to the cook, saying, "Here are four fish that have been brought to the Sultan. He wants you to cook them."

Then he went back to the Sultan, who told him to give the fisherman four hundred gold pieces. The fisherman, who had never before possessed such a large sum of money at once, could hardly believe his good fortune. He at once relieved the needs of his family, and made good use of it.

But now we must return to the kitchen, which we shall find in great confusion. The cook, when she had cleaned the fish, put them in a pan with some oil to fry them. When she thought them cooked enough on one side she turned them on the other. But scarcely had she done so when the walls of the kitchen opened, and there came out a young and beautiful damsel. She was dressed in an Egyptian dress of flowered satin, and she wore earrings, and a necklace of white pearls, and bracelets of gold set with rubies, and she held a wand of myrtle in her hand.

She went up to the pan, to the great astonishment of the cook, who stood motionless at the sight of her. She struck one of the fish with her rod, "Fish, fish," said she, "are you doing your duty?" The fish answered nothing, and then she repeated her question, whereupon they all raised their heads together and answered very distinctly, "Yes, yes. If you reckon, we reckon. If you pay your debts, we pay ours. If you fly, we conquer, and we are content."

When they had spoken the girl upset the pan, and entered the opening in the wall, which at once closed, and appeared the same as before.

When the cook had recovered from her fright she lifted up the fish which had fallen into the ashes, but she found them as black as cinders, and not fit to serve up to the Sultan. She began to cry.

"Alas! what shall I say to the Sultan? He will be so angry with me, and I know he will not believe me!"

Whilst she was crying the grand-vizir came in and asked if the fish were ready. She told him all that had happened, and he was much surprised. He sent at once for the fisherman, and when he came said to him, "Fisherman, bring me four more fish like you have brought already, for an accident has happened to them so that they cannot be served up to the Sultan."

The fisherman did not say what the genius had told him, but he excused himself from bringing them that day on account of the length of the way, and he promised to bring them next day.

In the night he went to the lake, cast his nets, and on drawing them in found four fish, which were like the others, each of a different colour.

He went back at once and carried them to the grand-vizir as he had promised.

He then took them to the kitchen and shut himself up with the cook, who began to cook them as she had done the four others on the previous day. When she was about to turn them on the other side, the wall opened, the damsel appeared, addressed the same words to the fish, received the same answer, and then overturned the pan and disappeared.

The grand-vizir was filled with astonishment. "I shall tell the Sultan all that has happened," said he. And he did so.

The Sultan was very much astounded, and wished to see this marvel for himself. So he sent for the fisherman, and asked him to procure four more fish. The fisherman asked for three days, which were granted, and he then cast his nets in the lake, and again caught four different coloured fish. The sultan was delighted to see he had got them, and gave him again four hundred gold pieces.

As soon as the Sultan had the fish he had them carried to his room with all that was needed to cook them.

Then he shut himself up with the grand-vizir, who began to prepare them and cook them. When they were done on one side he turned them over on the other. Then the wall of the room opened, but instead of the maiden a black slave came out. He was enormously tall, and carried a large green stick with which he touched the fish, saying in a terrible voice, "Fish, fish, are you doing your duty?" To these words the fish lifting up their heads replied, "Yes, yes.
