As it successively collects the streams of the plain of Colchos, the Phasis moves with diminished speed, though accumulated weight.

At the mouth it is sixty fathom deep, and half a league broad, but a small woody island is interposed in the midst of the channel; the water, so soon as it has deposited an earthy or metallic sediment, floats on the surface of the waves, and is no longer susceptible of corruption.

In a course of one hundred miles, forty of which are navigable for large vessels, the Phasis divides the celebrated region of Colchos, [66] or Mingrelia, [67] which, on three sides, is fortified by the Iberian and Armenian mountains, and whose maritime coast extends about two hundred miles from the neighborhood of Trebizond to Dioscurias and the confines of Circassia.

Both the soil and climate are relaxed by excessive moisture: twenty-eight rivers, besides the Phasis and his dependent streams, convey their waters to the sea; and the hollowness of the ground appears to indicate the subterraneous channels between the Euxine and the Caspian.

In the fields where wheat or barley is sown, the earth is too soft to sustain the action of the plough; but the gom, a small grain, not unlike the millet or coriander seed, supplies the ordinary food of the people; and the use of bread is confined to the prince and his nobles.
