supplied the want of discipline and courage. Fifteen generals, without concert or skill, led through the mountains of Armenia an army of thirty thousand Romans, inattentive to their signals, their ranks, and their ensigns. Four thousand Persians, intrenched in the camp of Dubis, vanquished, almost without a combat, this disorderly multitude; their useless arms were scattered along the road, and their horses sunk under the fatigue of their rapid flight. But the Arabs of the Roman party prevailed over their brethren; the Armenians returned to their allegiance; the cities of Dara and Edessa resisted a sudden assault and a regular siege, and the calamities of war were suspended by those of pestilence. A tacit or formal agreement between the two sovereigns protected the tranquillity of the Eastern frontier; and the arms of Chosroes were confined to the Colchian or Lazic war, which has been too minutely described by the historians of the times. The extreme length of the Euxine Sea from Constantinople to the mouth of the Phasis, may be computed as a voyage of nine days, and a measure of seven hundred miles. From the Iberian Caucasus, the most lofty and craggy mountains of Asia, that river descends with such oblique vehemence, that in a short space it is traversed by one hundred and twenty bridges. Nor does the stream become placid and navigable, till it reaches the town of Sarapana, five days' journey from the Cyrus, which flows from the same hills, but in a contrary direction to the Caspian Lake. The proximity of these rivers has suggested the practice, or at least the idea, of wafting the precious merchandise of India down the Oxus, over the Caspian, up the Cyrus, and with the current of the Phasis into the Euxine and Mediterranean Seas. 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, or Mingrelia, 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_,
