able stream, whicli comes from the same range to the point
of junction.
After the junction at Khaliph-abad, the Kerdistan river The Kerdktan
flows a little more southward, 1 and then, under the name 0 f branch •
the Jerahi, becomes not only navigable for country boats, but
carries a large body of water in a S.S.W. direction towards
Dorak. At six miles from this town, the river makes a deep
short bend to the south; and a great diminution of its waters
takes place, in consequence of six irrigating canals being cut
from it, to fertilize the populous country stretching west
ward. Part of the water thus diverted is carried into the
town, where it unites with the canal already mentioned as
coming from the Karun, near Sabla. This canal has been
mistaken for a branch of the Jerahi by those who have ob
served that boats occasionally pass along it from one river to
the other.
On these canals, as well as on the minor branches derived City of Dorak.
from the Jerahi, there are numerous villages, 2 having commu
nications one with another, as well as with the chief town,
by means of curious suspension-bridges, or more properly
dykes, the ropes and links of which are made entirely of
reeds. Dorak, the capital of the district, is situated in a
marshy plain, and contains about 6000 inhabitants, who live
in houses built with sun-dried bricks, and having sloping
roofs. It is defended by a fort and a mud wall, and is sur
rounded by date plantations. Commerce is carried on by
means of the canal with Mohammerah and Basrah, and the
people sometimes call it Little Basrah. 3
A few miles below the town the now diminished Jerahi The JeraW
enters some marshes, in which another portion is lost, whilst Persian Gulf,
the remainder, under the name of Lusbah, makes its way, by
a southerly course, to the Persian Gulf. The stream here,
though very much reduced, is still navigable for boats.
The last river to be noticed is the Tab, which, however,
only in part belongs to Khuzistan, since it forms, in the
