Then, if we may credit the story, the old man drew nearer to the chafing-dish which stood between them, and having fanned the dying embers in it, cast upon them a certain powder and some herbs, from whence as they burnt a peculiar smoke arose. As their vapors spread, he desired the prince to draw near and inhale them, and then (says the fable) assured him that when he should sleep he would find himself, in his dream, at whatever place he might desire, with this strange advantage, that he should see things in their truth and reality as well as in their outward shows. So the prince, not without some fear, prepared to obey; but first he drank his sherbet, and handed over the golden cup to the old man by way of recompense; then he reclined beside the chafing-dish and inhaled the heavy perfume till he became overpowered with sleep, and sank down upon the carpet in a dream. The prince knew not where he was, but a green country was floating before him, and he found himself standing in a marshy valley where a few wretched cottages were scattered here and there with no means of communication. There was a river, but it had overflowed its banks and made the central land impassable, the fences had been broken down by it, and the fields of corn laid low; a few wretched peasants were wandering about there; they looked half-clad and half-starved. "A miserable valley, indeed!" exclaimed the prince; but as he said it a man came down from the hills with a great bag of gold in his hand. "This valley is mine," said he to the people; "I have bought it for gold. Now make banks that the river may not overflow, and I will give you gold; also make fences and plant fields, and cover in the roofs of your houses, and buy yourselves richer clothing." So the people did so, and as the gold got lower in the bag the valley grew fairer and greener, till the prince exclaimed, "O gold, I see your value now! O wonderful, beneficent gold!" But presently the valley melted away like a mist, and the prince saw an army besieging a city; he heard a general haranguing his soldiers to urge them on, and the soldiers shouting and battering the walls; but shortly, when the city was well-nigh taken, he saw some men secretly giving gold among the soldiers, so much of it that they threw down their arms to pick it up, and said that the walls were so strong that they could not throw them down. "O powerful gold!" thought the prince; "thou art stronger than the city walls!" After that it seemed to him that he was walking about in a desert country, and in his dream he thought, "Now I know what labor is, for I have seen it, and its benefits; and I know what liberty is, for I have tasted it; I can wander where I will, and no man questions me; but gold is more strange to me than ever, for I have seen it buy both liberty and labor." Shortly after this he saw a great crowd digging upon a barren hill, and when he drew near he understood that he was to see the place whence the gold came.
