On leaving Cabul they marched through a great forest. Here they sat down on the grass to eat, while the horses were turned loose to feed. They were about to unload the elephant, which carried the dinner and the service, when it was discovered that Topaz and Ebony were no longer with the party. They called them loudly; the forest echoed with the names of Topaz and Ebony; the men sought them in every direction and filled the woods with their shouts, but they came back having seen no one and heard no answer. "We saw nothing," they said to Rustem, "but a vulture fighting with an eagle and plucking out all its feathers." The history of this struggle excited Rustem's curiosity; he went to the spot on foot. He saw no vulture or eagle, but he found that his elephant, still loaded with baggage, had been attacked by a huge rhinoceros. One was fighting with his horn, the other with his trunk. On seeing Rustem the rhinoceros retreated, and the elephant was led back. But now the horses were gone. "Strange things happen to travellers in the forest!" exclaimed Rustem. The servants were dismayed, and their master was in despair at having lost his horses, his favourite negro, and the sage Topaz, for whom he had always had a regard, though he did not always agree with his opinion. He was comforting himself with the hope of soon finding himself at the feet of the beautiful Princess of Cashmere, when he met a fine striped ass, which a vigorous peasant was beating violently with a stick. There is nothing rarer, swifter, or more beautiful than an ass of this kind. This one retorted on the rustic for his thrashing by kicks which might have uprooted an oak. The young Mirza very naturally took the ass's part, for it was a beautiful beast. The peasant ran off, crying out to the ass: "I will pay you out yet!" The ass thanked its liberator after its fashion, went up to him, fawned on him, and received his caresses. [Illustration: THE ASS RETORTED BY KICKS.] Having dined, Rustem mounted him, and took the road to Cashmere with his servants, some on foot and some riding the elephant. Hardly had he mounted his ass, when the animal turned towards Cabul, instead of proceeding on the way to Cashmere. In vain his rider tugged at the bridle, jerked at the bit, squeezed his ribs with his knees, drove the spurs into his flanks, gave him his head, pulled him up, whipped him right and left. The obstinate beast still made direct for Cabul. Rustem was growing desperate, when he met a camel-driver, who said to him-- "You have a very stubborn ass there, master, which insists on carrying you where you do not want to go. If you will let me have him, I will give you four of my camels, which you may choose for yourself."
