"After what I have seen," said the sultan to the vizier, "it will not be possible for me to be easy: these fish, without doubt, signify something extraordinary." He sent for the fisherman, and when he came, said to him, "Fisherman, the fish you have brought us, make me very uneasy; where did you catch them?" "Sir," answered he, "I fished for them in a lake situated betwixt four hills, beyond the mountain that we see from hence." "Knowst thou not that lake?" said the sultan to the vizier. "No," replied the vizier. "I never so much as heard of it, although I have for sixty years hunted beyond that mountain." The sultan asked the fisherman, how far the lake might be from the palace? The fisherman answered, it was not above three hours journey; upon this assurance, 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 lake, which they found to be situated betwixt four hills as the fisherman had described. The water was so transparent, that they observed all the fish to be like those which the fisherman had brought to the palace. The sultan stood upon the bank of the lake, and after beholding the fish with admiration, demanded of his courtiers, if it were possible they had never seen this lake, which was within so short a distance of the town. They all answered, that they had never so much as heard of it. "Since you all agree 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 learn how this lake came here, 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 lake. When night came, the sultan retired under his pavilion, and spoke to the grand vizier thus: "Vizier, my mind is uneasy: this lake transported hither; the black that appeared to us in my closet, and the fish that we heard speak; all these things so much excite my curiosity, that I cannot resist my impatient desire to have it satisfied. 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 wish to be alone; and the following days tell them the same thing, till I return."
