I was born, Commander of the Faithful, in Bagdad, and was left an orphan while I was yet a very young man, for my parents died within a few days of each other. I had inherited from them a small fortune, which I worked hard night and day to increase, till at last I found myself the owner of eighty camels. These I hired out to travelling merchants, whom I frequently accompanied on their various journeys, and always returned with large profits.  
One day I was coming back from Balsora, whither I had taken a supply of goods, intended for India, and halted at noon in a lonely place, which promised rich pasture for my camels. I was resting in the shade under a tree, when a dervish, going on foot towards Balsora, sat down by my side, and I inquired whence he had come and to what place he was going. We soon made friends, and after we had asked each other the usual questions, we produced the food we had with us, and satisfied our hunger.
 
While we were eating, the dervish happened to mention that in a spot only a little way off from where we were sitting, there was hidden a treasure so great that if my eighty camels were loaded till they could carry no more, the hiding place would seem as full as if it had never been touched.
 
At this news I became almost beside myself with joy and greed, and I flung my arms round the neck of the dervish, exclaiming: "Good dervish, I see plainly that the riches of this world are nothing to you, therefore of what use is the knowledge of this treasure to you? Alone and on foot, you could carry away a mere handful. But tell me where it is, and I will load my eighty camels with it, and give you one of them as a token of my gratitude."
 
Certainly my offer does not sound very magnificent, but it was great to me, for at his words a wave of covetousness had swept over my heart, and I almost felt as if the seventy-nine camels that were left were nothing in comparison.
 
The dervish saw quite well what was passing in my mind, but he did not show what he thought of my proposal.
 
"My brother," he answered quietly, "you know as well as I do, that you are behaving unjustly. It was open to me to keep my secret, and to reserve the treasure for myself. But the fact that I have told you of its existence shows that I had confidence in you, and that I hoped to earn your gratitude for ever, by making your fortune as well as mine. But before I reveal to you the secret of the treasure, you must swear that, after we have loaded the camels with as much as they can carry, you will give half to me, and let us go our own ways. I think you will see that this is fair, for if you present me with forty camels, I on my side will give you the means of buying a thousand more."
 
I could not of course deny that what the dervish said was perfectly reasonable, but, in spite of that, the thought that the dervish would be as rich as I was unbearable to me. Still there was no use in discussing the matter, and I had to accept his conditions or bewail to the end of my life the loss of immense wealth. So I collected my camels and we set out together under the guidance of the dervish. After walking some time, we reached what looked like a valley, but with such a narrow entrance that my camels could only pass one by one. The little valley, or open space, was shut up by two mountains, whose sides were formed of straight cliffs, which no human being could climb.
 
When we were exactly between these mountains the dervish stopped.
 
"Make your camels lie down in this open space," he said, "so that we can easily load them; then we will go to the treasure."
 
I did what I was bid, and rejoined the dervish, whom I found trying to kindle a fire out of some dry wood. As soon as it was alight, he threw on it a handful of perfumes, and pronounced a few words that I did not understand, and immediately a thick column of smoke rose high into the air. He separated the smoke into two columns, and then I saw a rock, which stood like a pillar between the two mountains, slowly open, and a splendid palace appear within.
 
But, Commander of the Faithful, the love of gold had taken such possession of my heart, that I could not even stop to examine the riches, but fell upon the first pile of gold within my reach and began to heap it into a sack that I had brought with me.
 
The dervish likewise set to work, but I soon noticed that he confined himself to collecting precious stones, and I felt I should be wise to follow his example. At length the camels were loaded with as much as they could carry, and nothing remained but to seal up the treasure, and go our ways.
 
Before, however, this was done, the dervish went up to a great golden vase, beautifully chased, and took from it a small wooden box, which he hid in the bosom of his dress, merely saying that it contained a special kind of ointment. Then he once more kindled the fire, threw on the perfume, and murmured the unknown spell, and the rock closed, and stood whole as before.
 
The next thing was to divide the camels, and to charge them with the treasure, after which we each took command of our own and marched out of the valley, till we reached the place in the high road where the routes diverge, and then we parted, the dervish going towards Balsora, and I to Bagdad. We embraced each other tenderly, and I poured out my gratitude for the honour he had done me, in singling me out for this great wealth, and having said a hearty farewell we turned our backs, and hastened after our camels.
 
I had hardly come up with mine when the demon of envy filled my soul. "What does a dervish want with riches like that?" I said to myself. "He alone has the secret of the treasure, and can always get as much as he wants," and I halted my camels by the roadside, and ran back after him.
 
I was a quick runner, and it did not take me very long to come up with him. "My brother," I exclaimed, as soon as I could speak, "almost at the moment of our leave-taking, a reflection occurred to me, which is perhaps new to you. You are a dervish by profession, and live a very quiet life, only caring to do good, and careless of the things of this world. You do not realise the burden that you lay upon yourself, when you gather into your hands such great wealth, besides the fact that no one, who is not accustomed to camels from his birth, can ever manage the stubborn beasts. If you are wise, you will not encumber yourself with more than thirty, and you will find those trouble enough."
 
"You are right," replied the dervish, who understood me quite well, but did not wish to fight the matter. "I confess I had not thought about it. Choose any ten you like, and drive them before you."
 
I selected ten of the best camels, and we proceeded along the road, to rejoin those I had left behind. I had got what I wanted, but I had found the dervish so easy to deal with, that I rather regretted I had not asked for ten more. I looked back. He had only gone a few paces, and I called after him.
 
"My brother," I said, "I am unwilling to part from you without pointin............
