Hardly had he done so than a crowd of men were seen pouring out of the camp.

‘How can we thank you!’ they exclaimed, pressing round the youth. ‘Our camels as well as ourselves are almost dead of thirst. See! here is the rope we have brought to let you down.’

‘Come, then,’ answered the youth. And they all set out.

On reaching the well, the rope was knotted securely under his arms, a big goat-skin bottle was given him, and he was gently lowered to the bottom of the pit. Here a clear stream was bubbling over the rocks, and, stooping down, he was about to drink, when a huge Arab appeared before him, saying in a loud voice:

‘Come with me!’

The young man rose, never doubting that his last hour had come; but as he could do nothing, he followed the Arab into a brilliantly lighted hall, on the further side of the little river. There his guide sat down, and drawing towards him two boys, one black and the other white, he said to the stranger:

‘I have a question to ask you. If you answer it right, your life shall be spared. If not, your head will be forfeit, as the head of many another has been before you. Tell me: which of my two children do I think the handsomer.’

The question did not seem a hard one, for while the white boy was as beautiful a child as ever was seen, his brother was ugly even for a negro. But, just as the youth was going to speak, the old man’s counsel flashed into the youth’s mind, and he replied hastily: ‘The one whom we love best is always the handsomest.’

‘You have saved me!’ cried the Arab, rising quickly from his seat, and pressing the young man in his arms. ‘Ah! if you could only guess what I have suffered from the stupidity of all the people to whom I have put that question, and I was condemned by a wicked genius to remain here until it was answered! But what brought you to this place, and how can I reward you for what you have done for me?’

‘By helping me to draw enough water for my caravan of eighty merchants and their camels, who are dying for want of it,’ replied the youth.
