The Persian turned and seeing him thus standing laughed and said to him, "Art thou mad? What! I in my heart purpose thee good and thou misdoubtest I will harm thee!" presently adding, "But, if thou fear to go with me to my house, I will go with thee to thine and teach thee there." Hasan replied, "'Tis well, O uncle," and the Persian rejoined, "Go thou before me." So Hasan led the way to his own house, and entering, told his mother of the Persian's coming, for he had left him standing at the door. She ordered the house for them and when she had made an end of furnishing and adorning it, her son bade her go to one of the neighbours' lodgings. So she left her home to them and wended her way, whereupon Hasan brought in the Persian, who entered after asking leave. Then he took in hand a dish and going to the market, returned with food, which he set before the Persian, saying, "Eat, O my lord, that between us there may be bread and salt and may Almighty Allah do vengeance upon the traitor to bread and salt!" The Persian replied with a smile, "True, O my son! Who knoweth the virtue and worth of bread and salt?"[FN#18] Then he came forward and ate with Hasan, till they were satisfied; after which the Ajami said, "O my son Hasan, bring us somewhat of sweetmeats." So Hasan went to the market, rejoicing in his words, and returned with ten saucers[FN#19] of sweetmeats, of which they both ate and the Persian said, "May Allah abundantly requite thee, O my son!

But hardly did Hasan hear these words than he went forth like a colt let out to grass in spring-tide, and hastening to the shop, fetched the apparatus and set it before the Persian, who pulled out a piece of paper and said, "O Hasan, by the bond of bread and salt, wert thou not dearer to me than my son, I would not let thee into the mysteries of this art, for I have none of the Elixir[FN#21] left save what is in this paper; but by and by I will compound the simples whereof it is composed and will make it before thee. Know, O my son Hasan, that to every ten pounds of copper thou must set half a drachm of that which is in this paper, and the whole ten will presently become unalloyed virgin gold;" presently adding, "O my son, O Hasan, there are in this paper three ounces,[FN#22] Egyptian measure, and when it is spent, I will make thee other and more." Hasan took the packet and finding therein a yellow powder, finer than the first, said to the Persian, "O my lord, what is the name of this substance and where is it found and how is it made?" But he laughed, longing to get hold of the youth, and replied, "Of what dost thou question? Indeed thou art a froward boy! Do thy work and hold thy peace." So Hasan arose and fetching a brass platter from the house, shore it in shreds and threw it into the melting-pot; then he scattered
