. about long. 50 deg. to 51 deg., and lat.
31 deg. 30'. These head-streams have a general direction from N.E. to S.W.
The principal of them is the Kurdistan river, which rises about fifty
miles to the north-east of Babahan and flowing south-west to that point,
then bends round to the north, and runs north-west nearly to the fort
of Mungasht, where it resumes its original direction, and receiving from
the north-east the Abi Zard, or "Yellow River"--a delightful stream of
the coldest and purest water possible--becomes known as the Jerahi, and
carries a large body of water as far as Fellahiyeh or Dorak. Near Dorak
the waters of the Jerahi are drawn off into a number of canals, and the
river is thus greatly diminished; but still the stream struggles on, and
proceeds by a southerly course towards the Persian Gulf, which it enters
near Gadi in long. 48 deg. 52'. The course of the Jerahi, exclusively of
the smaller windings, is about equal in length to that of the Tab or
Hindyan. In volume, before its dispersion, it is considerably greater
than that river. It has a breadth of about a hundred yards before it
reaches Babahan, and is navigable for boats almost from its junction
with the Abi Zard. Its size is, however, greatly reduced in its lower
course, and travellers who skirt the coast regard the Tab as the more
important river.

The Kuran is a river very much exceeding in size both the Tab and the
Jerahi. It is formed by the junction of two large streams--the Dizful
river and the Kuran proper, or river of Shuster. Of these the Shuster
stream is the more eastern. It rises in the Zarduh Kuh, or "Yellow
Mountain," in lat. 32 deg., long. 51 deg., almost opposite to the river Isfahan.
From its source it is a large stream. Its direction is at first to the
southeast, but after a while it sweeps round and runs considerably north
of west; and this course it pursues through the mountains, receiving
tributaries of importance from both sides, till, near Akhili, it turns
round to the south, and, cutting at a right angle the outermost of the
Zagros ranges, flows down with a course S.W. by S. nearly to Sinister,
where, in consequence of a bund or dam thrown across it, it bifurcates,
and passes in two streams to the right and to the left of the town.
The right branch, which earned commonly about two thirds of the water,
proceeds by a tortuous course of nearly forty miles, in a direction a
very little west of south, to its junction with the Di
