At Antioch it is fifty yards in width, and runs rapidly.

The natives now call it the Nahr-el-Asy, or "Rebel River," either from its running in an opposite direction to all other streams of the country, or (more probably) from its violence and impetuosity.
There is one tributary of the Orontes which deserves a cursory mention.
This is the Kara Su, or "Black River," which reaches it from the Aga Denghis, or Bahr-el-Abiyad, about five miles below Jisr Hadid and four or five above Antioch.

This stream brings into the Orontes the greater part of the water that is drained from the southern side of Amanus.

It is formed by a union of two rivers, the upper Kara Su and the Afrin, which flow into the Aga Denghis (White Sea), or Lake of Antioch, from the north-west, the one entering it at its northern, the other at its eastern extremity.

Both are considerable streams; and the Kara Su on issuing from the lake carries a greater body of water than the Orontes itself, and thus adds largely to the volume of that stream in its lower course from the point of junction to the Mediterranean.
The Litany, or river of Tyre, rises from a source at no great distance from the head springs of the Orontes.
