THE JORAK, OR ACAMPSIS.
[CHAP. I.
The numerous windings of the Aras appear to give about
830 miles from its source to the sea; and of this length, 560
miles extend through the rich valleys of Eastern, or Persian
Armenia.
It is proper to notice that there is, in the tract of country
of which we are speaking, the source of another river, which is
also of the first class, although considerably smaller than the
others. This is the Jorak, or Acampsis, which rises about
30 miles north of Erz-Rum, and is, according to Mr. Brant's
description, " one of the largest rivers of Armenia." It unites
the waters on the western and northern sides of the mountains
containing the sources of the Kur, Aras, Arpahchai*, or
Harpasus, and the Western Euphrates, which serve as drains
to the valleys on the opposite sides of the chain. Rafts come
down the Jorak, from Atvin to the sea, in three days; and
sometimes, though rarely, track up against the stream in eight
or ten ; but, from all that I could learn, the river is not navi
gable for boats, on account of rapids and rocks. The windings
of the river Jorak seem to give a course of about 200 miles;
it bounds Colchis to the west; and is, in all probability, the
Bathys, which, according to Pliny, 1 is a river of Colchis.
