At length they came before a palace built of emeralds,
encompassed by a wide moat, on the banks whereof, at certain
distances, were planted such tall trees, that they shaded the
whole palace. Before the gate, which was of massive gold, was a
bridge, formed of one single shell of a fish, though it was at

bridge stood a company of genii, of a prodigious height, who
guarded the entrance into the castle with great clubs of China

back, giving the other two to the prince, who did the like. Then
Mobarec laid on the ground two large table-cloths, on the edges
whereof he scattered some precious stones, musk, and amber.

other; and Mobarec said to the prince, "I shall now, sir, conjure
the sultan of the genii, who lives in the palace that is before
us; may he come in a peaceable mood to us! I confess I am not
without apprehension about the reception he may give us. If our
coming into this island is displeasing to him, he will appear in
the shape of a dreadful monster; but if he approves of your
design, he will shew himself in the shape of a handsome man. As
soon as he appears before us, you must rise and salute him,
without going off your cloth; for you would certainly perish,
should you stir from it. You must say to him, 'Sovereign lord of
the genii, my father, who was your servant, has been taken away
