"Your comparison is not flattering," said the proud Persian, contracting his brows. "Boy! Do you presume to think me an object of pity?"

Robin could only answer "Yes," for he thought, "No one is more to be pitied than the man who tries to run away from himself."

Young Hartley expected the angry Amir to bid him instantly dismount, but Ali only urged on his own horse as if impatient to reach the next encampment.

That simple "yes" had startled the Persian more than any eloquence could have done. "Is it possible," he said to himself, "that this friendless, helpless, hopeless outcast can afford to look down with compassion on me? Is this boy a prophet that he can read at a glance secret misery hidden in the depths of a stranger's heart!"

Robin, in the Amir's company, travelled far more comfortably than he had done with the Shararat Bedouin Arabs. Persians know something of cookery, and indulge in the luxury of tea; while Arabs prefer the delicious coffee which their country supplies. Robin could choose between the two refreshing beverages. His need of change of garments was supplied by the generous Persian, and Robin, arrayed in an Oriental costume, was far more picturesquely attired than he had ever been before.

But every kindness shown to the kafir (infidel), as Hassan called the Christian, was as gall and wormwood to the soul of the Amir's "shadow." Everything given to the stranger seemed to this man as if taken from himself, and the wily Persian hated the frank Englishman with a deadly hatred. Hassan had picked up some English in India, though not nearly as much as the Amir had done, and he used it as a weapon of annoyance to Robin, who found it hard to keep his temper when thus offered gratuitous provocation.

Hassan, not contented with insulting one who had done him no wrong, used his utmost skill to poison the mind of the Amir against his English companion. But here the clear, crystal-like transparency of Robin's character proved his defence; much might be thrown on it by malice, but malice itself could not make it stick. Ali could not help trusting the English youth who said out frankly and fearlessly whatever he thought.

And often did Ali ponder over the words which had made him angry when they were uttered: "You are weary and very thirsty, and you know of no water near; perhaps God sent you to me that I might tell you where to find it."
