CHALUS(Χάλος), a river of Syria, four days' march from Myriandrus, full of fish, which were held sacred by the inhabitants (Xen. Anab. 1.4. 9). Though the identity has not been made out sufficiently, it is in all probability the same as the Koweïkwhich takes its rise from two sources in the high ground S. of ‘Aïntáb;the larger, owing to the abundance of its fish, has the name Bâluk Sú(fish river). From the pass in the Béilánchain advancing NE. and keeping quite clear of the lake of Agá Denghízand the surrounding marshes, it is about 61 geographical miles to the upper part of the Balúk Sú, and about 68 or 70 miles from the town of Beilan, if a greater sweep be made to the N along the slopes of the hills. As there were three rivers to cross, the Kará Sú, the Aswádand the ‘Afrin, four days would be required for this part of the march. (Chesney, Exped. Euphrat. vol. 1. p. 412, 2. p. 212.)
