After what I have seen, says the sultan to the vizier, it will not be possible for me to be easy in my mind. These fish, without doubt, signify something extraordinary, in which I have a mind to be satisfied. He sent for the fisherman; and when he came, says to him, Fisherman, the fishes you have brought us make me very uneasy; where did you catch them? Sir, answers he, I fished for them in a pond situate betwixt four hills, beyond the mountain that we see from hence. Know you that pond, says the sultan to the vizier? No, sir, replies the vizier, I never so much as heard of it; and yet it is not sixty years since I hunted beyond that mountain and thereabouts. The sultan asked the fisherman, how far the pond might be from the palace? The fisherman answered, it was not above three hours journey. Upon this assurance, and there being day enough beforehand, the sultan commanded all his court to take horse, and the fisherman served them for a guide. They all ascended the mountain, and at the foot of it they saw, to their great surprise, a vast plain, that nobody had observed till then; and at last they came to the pond, which they found actually to be situate betwixt four hills, as the fisherman had said. The water of it was so transparent, that they observed all the fishes to be like those which the fisherman had brought to the palace.

The sultan staid upon the bank of the pond, and, after beholding the fishes with admiration, he demanded of his emirs and all his courtiers, if it was possible they had never seen this pond, which was within so little a way of the town. They all answered, that they had never so much as heard of it.

Since you all agree, says he, that you never heard of it, and as I am no less astonished than you are, at this novelty I am resolved not to return to my palace till I know how this pond came hither, and why all the fish in it are of four colours. Having spoken thus, he ordered his court to encamp, and immediately his pavilion, and the tents of his household, were planted upon the banks of the pond.

When night came, the sultan retired under his pavilion, and spoke to the vizier by himself thus: Vizier, my mind is very uneasy: this pond transported hither, the black that appeared to us in my closet, and the fishes that we heard speak; all this does so much whet my curiosity, that I cannot resist the impatient desire that I have to be satisfied in it. To this end, I am resolved to withdraw alone from the camp, and I order you to keep my absence secret; stay in my pavilion, and to-morrow morning, when the emirs and courtiers come to attend my levee, send them away, and tell them, that I am somewhat indisposed, and have a mind to be alone: and the following day tell them the same thing, till I return.

The grand vizier said several things to divert the sultan from his design: He represented to him the danger to which he might be exposed, and that all his labour might perhaps be in vain. But it was to no purpose; the sultan was resolved on it, and would go. He put on a suit fit for walking, and took his scimitar; and as soon as he saw that all was quiet in the camp, he goes out alone, and went over one of the hills without much difficulty; he found the descent still more easy, and, when he came to the plain, walked on till the sun rose, and then he saw before him, at a considerable distance, a great building. He rejoiced at the sight, in hopes to be informed there of what he had a mind to know. When he came near, he found it was a magnificent palace, or rather a very strong castle, of fine black polished marble, and covered with fine steel, as smooth as a looking-glass. Being mightily pleased that he had so speedily met with something worthy his curiosity, he stopped before the front of the castle, and considered it with abundance of attention.

He afterwards came up to the gate, which had two leaves, one of them open: though he might have entered when he would, yet he thought it best to knock. He knocked at first softly, "and waited for some time; but seeing nobody, and supposing they had not heard him, he knocked harder the second time; but neither seeing nor hearing anybody, he knocked again and again; but nobody appearing, it surprised him extremely; for he could not think that a castle so well in repair was without inhabitants. If there be nobody in it, says he to himself, I have nothing to fear, and if there be, I have wherewith to defend me.

At last he entered, and when he came within the porch, he cries, Is there nobody here to receive a stranger, who comes in for some refreshment as he passes by? He repeated the same two or three times; but, though he spoke very high, nobody answered.

This silence increased his astonishment; he came into a very spacious court, and looking on every side to see if he could perceive any body, he saw no living thing. But, sir, says Scheherazade, day appears, and I must stop.

Ah! sister, says Dinarzade, you break off at the very best of the story. It is true, answers the sultaness; but, sister, you see I am forced to do so. If my lord the sultan pleases, you may hear the rest to-morrow, Schahriar agreed to this, not so much to please Dinarzade as to satisfy his own curiosity, being mightily impatient to hear what adventure the prince met with in the castle.

The Twenty-first Night.
