He used to ride on Horse-chestnut, and Tumbu was always of the party, getting in consequence rather too fat, by reason of the rich food which was given him.

But despite all this fun and jollity little Prince Akbar was not quite satisfied.

"You took my mother away with you to the hills," he would say to his father. "Why didn't you bring her back with you? I want to see her."

Then King Humâyon would laugh—for he was always merry—and bid his little son be patient. His mother would come with the spring. At present she was in Persia, but so soon as the passes were open she would start for Kâbul. And then there would be fun! Whereupon little Prince Akbar would smile a dignified smile, and say, of course there would be fun!

Now out of this arose a plan which came into King Humâyon's head, as so many other plans came, without very much thought; for he was full of kindly, not over-wise fancies. And this one was that little Prince Akbar should choose his own mother!

It would be rather a hard task for a child who had not seen her for two years and a half, and who was but a baby of less than eighteen months old when he had parted from her! But Humâyon was convinced that his son would remember; and anyway, even if he did not, no harm would be done and it would be very amusing. So orders were given for a huge entertainment in the Arta Gardens just outside Kâbul. They were the most beautiful gardens, not close cropped and orderly like English gardens, but with wide, bare, marble-paved walks and squares, big marble-stepped tanks full of waterlilies, all set in tangles of widespread roses and jasmine and gardenia. And here Humâyon's fancy set up a Mystic Palace of three Houses: The House of Pleasure; The House of Fortune, and the House of Power. Never was such a beautiful Palace. By day it shone with the reflected light of thousands and thousands of looking-glasses, by night it rose outlined in every detail by thousands and thousands of little lamps. Every marble path was spread with priceless silken carpets, the very fountains were scented with attar-of-rose. All the musicians and dancers and acrobats and jugglers of Kâbul were commanded to be there, snow came from the higher hills to ice the drinks, and cooks worked day and night to prepare the most wonderful dishes.

"That is what I call a King," remarked the Afghan sentry, whom Roy, going with his little master to see the preparations, found keeping guard at the gate. "None of your skinflints like Kumran. Aye!" he continued, seeing Roy's look of surprise and distaste, "I have done what I said I would—fought for Kumran till there was no more fighting to be done. And now, like His Gracious Majesty King Humâyon, I am enjoying myself. I want no more! Ha! Ha!"

Little Prince Akbar, who was standing by, turned on him sharply. "Thou art a slave, fellow, and know nothing of Kingship. Roy and I do. In his country Kings ride and shoot and play polo, and—and do things. Besides," he added, "I want my mother."

"Your Highness will have to choose her then, so I hear," began the sentry almost rudely, and Roy started to rebuke him, but Prince Akbar was first.

"Of course I shall choose my own mother, slave. She is quite different, you know, from any one else in the world. Isn't she, Roy?"
