In the reign of Haroun-al-Raschid, there lived in Bagdad a merchant named Ali Cogia, who, having neither wife nor child, contented himself with the modest profits produced by his trade. He had spent some years quite happily in the house his father had left him, when three nights running he dreamed that an old man had appeared to him, and reproached him for having neglected the duty of a good Mussulman, in delaying so long his pilgrimage to Mecca.  
Ali Cogia was much troubled by this dream, as he was unwilling to give up his shop, and lose all his customers. He had shut his eyes for some time to the necessity of performing this pilgrimage, and tried to atone to his conscience by an extra number of good works, but the dream seemed to him a direct warning, and he resolved to put the journey off no longer.
 
The first thing he did was to sell his furniture and the wares he had in his shop, only reserving to himself such goods as he might trade with on the road. The shop itself he sold also, and easily found a tenant for his private house. The only matter he could not settle satisfactorily was the safe custody of a thousand pieces of gold which he wished to leave behind him.
 
After some thought, Ali Cogia hit upon a plan which seemed a safe one. He took a large vase, and placing the money in the bottom of it, filled up the rest with olives. After corking the vase tightly down, he carried it to one of his friends, a merchant like himself, and said to him:
 
"My brother, you have probably heard that I am staffing with a caravan in a few days for Mecca. I have come to ask whether you would do me the favour to keep this vase of olives for me till I come back?"
 
The merchant replied readily, "Look, this is the key of my shop: take it, and put the vase wherever you like. I promise that you shall find it in the same place on your return."
 
A few days later, Ali Cogia mounted the camel that he had laden with merchandise, joined the caravan, and arrived in due time at Mecca. Like the other pilgrims he visited the sacred Mosque, and after all his religious duties were performed, he set out his goods to the best advantage, hoping to gain some customers among the passers-by.
 
Very soon two merchants stopped before the pile, and when they had turned it over, one said to the other:
 
"If this man was wise he would take these things to Cairo, where he would get a much better price than he is likely to do here."
 
Ali Cogia heard the words, and lost no time in following the advice. He packed up his wares, and instead of returning to Bagdad, joined a caravan that was going to Cairo. The results of the journey gladdened his heart. He sold off everything almost directly, and bought a stock of Egyptian curiosities, which he intended selling at Damascus; but as the caravan with which he would have to travel would not be starting for another six weeks, he took advantage of the delay to visit the Pyramids, and some of the cities along the banks of the Nile.
 
Now the attractions of Damascus so fascinated the worthy Ali, that he could hardly tear himself away, but at length he remembered that he had a home in Bagdad, meaning to return by way of Aleppo, and after he had crossed the Euphrates, to follow the course of the Tigris.
 
But when he reached Mossoul, Ali had made such friends with some Persian merchants, that they persuaded him to accompany them to their native land, and even as far as India, and so it came to pass that seven years had slipped by since he had left Bagdad, and during all that time the friend with whom he had left the vase of olives had never once thought of him or of it. In fact, it was only a month before Ali Cogia's actual return that the affair came into his head at all, owing to his wife's remarking one day, that it was a long time since she had eaten any olives, and would like some.
 
"That reminds me," said the husband, "that before Ali Cogia went to Mecca seven years ago, he left a vase of olives in my care. But really by this time he must be dead, and there is no reason we should not eat the olives if we like. Give me a light, and I will fetch them and see how they taste."
 
"My husband," answered the wife, "beware, I pray, of your doing anything so base! Supposing seven years have passed without news of Ali Cogia, he need not be dead for all that, and may come back any day. How shameful it would be to have to confess that you had betrayed your trust and broken the seal of the vase! Pay no attention to my idle words, I really have no desire for olives now. And probably after all this while they are no longer good. I have a presentiment that Ali Cogia will return, and what will he think of you? Give it up, I entreat."
 
The merchant, however, refused to listen to her advice, sensible though it was. He took a light and a dish and went into his shop.
 
"If you will be so obstinate," said his wife, "I cannot help it; but do not blame me if it turns out ill."
 
When the merchant opened the vase he found the topmost olives were rotten, and in order to see if the under ones were in better condition he shook some out into the dish. As they fell out a few of the gold pieces fell out too.
 
The sight of the money roused all the merchant's greed. He looked into the vase, and saw that all the bottom was filled with gold. He then replaced the olives and returned to his wife.
 
"My wife," he said, as he entered the room, "you were quite right; the olives are rotten, and I have recorked the vase so well that Ali Cogia will never know it has been touched."
 
"You would have done better to believe me," replied the wife. "I trust that no harm will come of it."
 
These words made no more impression on the merchant than the others had done; and he spent the whole night in wondering how he could manage to keep the gold if Ali Cogia should come back and claim his vase. Very early next morning he went out and bought fresh new olives; he then threw away the old ones, took out the gold and hid it, and filled up the vase with the olives he had bought. This done he recorked the vase and put it in the same place where it had been left by Ali Cogia.
 
A month later Ali Cogia re-entered Bagdad, and as his house was still let he went to an inn; and the following day set out to see his friend the merchant, who received him with open arms and many expressions of surprise. After a few moments given to inquiries Ali Cogia begged the merchant to hand him over the vase that he had taken care of for so long.
 
"Oh certainly," said he, "I am only glad I could be of use to you in the matter. Here is the key of my shop; you will find the vase in the place where you put it."
 
Ali Cogia fetched his vase and carried it to his room at the inn, where he opened it. He thrust down his hand but could feel no money, but still was persuaded it must be there. So he got some plates and vessels from his travelling kit and emptied out the olives. To no purpose. The gold was not there. The poor man was dumb with horror, then, lifting up his hands, he exclaimed, "Can my old friend really have committed such a crime?"
 
In great haste he went back to the house of the merchant. "My friend," he cried, "you will be astonished to see me again, but I can find nowhere in this vase a thousand pieces of gold that I placed in the bottom under the olives. Perhaps you may have taken a loan of them for your business purposes; if that is so you are most welcome. I will only ask you to give me a receipt, and you can pay the money at your leisure."
 
The merchant, who had expected something of the sort, had his reply all ready. "Ali Cogia," he said, "when you brought me the vase of olives did I ever touch it?"
 
"I gave you the key of my shop and you put it yourself where you liked, and did you not find it in exactly the same spot and in the same state? If you placed any gold in it, it must be there still. I know nothing about that; you only told me there were olives. You can believe me or not, but I have not laid a finger on the vase."
 
Ali Cogia still tried every means to persuade the merchant to admit the truth. "I love peace," he said, "and shall deeply regret having to resort to harsh measures. Once more, think of your reputation. I shall be in despair if you oblige me to call in the aid of the law."
 
"Ali Cogia," answered the merchant, "you allow that it was a vase of olives you placed in my charge. You fetched it and removed it yourself, and now you tell me it contained a thousand pieces of gold, and that I must restore them to you! Did you ever say anything about them before? Why, I did not even know that the vase had olives in it! You never showed them to me. I wonder you have not demanded pearls or diamonds. Retire, I pray you, lest a crowd should gather in front of my shop."
 
By this time not only the casual passers-by, but also the neighbouring merchants, were standing round, listening to the dispute, and trying every now and then to smooth matters between them. But at the merchant's last words Ali Cogia resolved to lay the cause of the quarrel before them, and told them the whole story. They heard him to the end, and inquired of the merchant what he had to say.
 
The accused man admitted that he had kept Ali Cogia's vase in his shop; but he denied having touched it, and swore that as to what it contained he only knew what Ali Cogia had told him, and called them all to witness the insult that had been put upon him.
 
"You have brought it on yourself," said Ali Cogia, taking him by the arm, "and as you appeal to the law, the law you shall have! Let ............
