is swift horses.
Haddad-Ben-Ahab was in consequence constrained to pay and part from him,
and to embark in a ferry-boat to convey him over the stream, where he
found a strange vehicle with four horses standing ready to carry him on
towards the wall of the world, "which surely," said he to himself,
"ought not to be now far off."

Haddad-Ben-Ahab showed his gold again, and was permitted to take a seat
in the vehicle, which soon after drove away; and he remarked, in a most
sagacious manner, that nothing in that country was like the things in
his own; for the houses and trees and all things ran away as the vehicle
came up to them; and when it gave a jostle, they gave a jump; which he
noted as one of the most extraordinary things he had seen since he left
Bagdad.

At last Haddad-Ben-Ahab came to the foot of a lofty green mountain, with
groves and jocund villages, which studded it, as it were, with gems and
shining ornaments, and he said, "This must be the wall of the world, for
surely nothing can exist on the other side of these hills! but I will
ascend them and look over, for I should like to tell my friends in
Bagdad what is to be seen on the outside of the earth." Accordingly he
ascended the green mountain, and he came to a thick forest of stubby
trees: "This is surprising," said Haddad-Ben-Ahab, "but higher I will

solitude without limit, and the living world all glittering at the foot
of the mountain.

"This is a high place," said Haddad-Ben-Ahab, "but I will yet go
higher," and he began to climb with his hands. After an upward journey
of great toil he came to a frozen region, and the top of the wall of the
world was still far above him. He was, however, none daunted by the
distance, but boldly held on in the ascent, and at last he reached the
top of the wall. But when he got there, instead of a region of fog and
chaos, he only beheld another world much like our own, and he was
greatly amazed, and exclaimed with a loud voice,--"Will my friends in
Bagdad believe this?--but it is true, and I will so tell them." So he
hastened down the mountain, and went with all the speed he could back to
Bagdad; saying, "Bagdad," and giving gold to every man he met, until he
reached the kiosk of dreams, where his friends were smoking and looking
at the gambols of the Tigris.

When the friends o
