se of need, he would hasten to his assistance;
and he therefore left the vault, in company with Fatima, to hunt up the
robber.

In the same village which had witnessed his transformation into a
physician, he bought a horse with what money remained to him, and
procured a lodging for Fatima with a poor woman who lived in the
suburb. He then hastened toward the hills where he had first met
Orbasan, and arrived there in three days. He soon found their tents, and
appeared unexpectedly to Orbasan, who greeted him with friendliness. He
gave an account of his failures, at which the grave Orbasan could not
refrain from laughing now and then, especially when he thought of the
physician Chakamankabudibaba. But he was terribly enraged over the
treachery of the ugly little monster, Hassan, and swore he would hang
him up wherever he found him. He also promised that when my brother had
refreshed himself after the fatigue of his journey, he would be ready to
assist him.

Mustapha therefore spent the night in Orbasan's tent. With the early
dawn they rode off, accompanied by three of Orbasan's bravest men well
mounted and armed. They rode very fast and in two days' time reached
the place where Mustapha had left Fatima. They took her with them, and
journeyed on until they came to the small wood from whence Thiuli's
castle could be seen, where they went into camp until night should
come.

As soon as it was dark, guided by Fatima, they stole up to the brook
where the aqueduct began, and soon discovered the entrance. There they

the conduit; but before they went in, Fatima repeated once more her
instructions to them--they would emerge from the fountain into the
inner court, in the right and left corners of which were towers, and in
the sixth door counting from the right tower, they would find Fatima
and Zoraide, guarded by two black slaves. Well provided with weapons and
crowbars, Mustapha, Orbasan, and two other men, descended into the
aqueduct. They sank to their hips in the water, but none the less did
they advance valiantly forward. In half an hour they came to the
fountain, and at once began to use their crowbars. The wall was thick
and solid but could not long withstand the united strength of the four
men, and they had soon made an opening large enough to crawl through.
Orbasan passed through first, and helped the others after him.

When they all stood in the c
