with the finest of timber for constructing their ships, and was sought by kings from the treeless valleys of the Tigris, Euphrates and Nile. Unfortunately, after centuries of exploitation, culminating in use by the Ottoman Turks for railroad fuel from 1914 to 1918, the cedar survives only in small groves, the best known of which is that above Bisharri, where more than four hundred trees still grow. Some of these are perhaps a thousand years old, and eighty feet tall. One has been adopted as an emblem by the modern Republic of Lebanon.
The third floral zone comprises the canyon-like trough and the plateaus of eastern Syria, where intense heat and scanty rainfall combine to produce a steppe regime in which trees all but disappear, grasses tend to have a seasonal existence, and only coarse shrubs and thorny bushes survive. The Orontes and the Jordan flow in deep beds and are of little use for irrigation. The Hawran and Transjordan plateaus are sufficiently high to condense enough of the remaining westerly moisture to permit pasturage.
Goats and sheep, particularly goats, have furthered the process of erosion by eating up grass and young sprouts on the hillsides, leaving the soil loose and more exposed to the action of running water. Because of the relief of the Lebanon mountains and the over-drainage of the Palestinian highlands, Syria has always had scant natural grazing for cattle and horses, but sheep and goats can find enough forage.
Originally an American wild animal, the horse found its way into eastern Asia in remote prehistoric times and, while still in wild form, made its way as far as Palestine. It was domesticated in early antiquity somewhere east of the Caspian Sea by Indo-European nomads, and then imported into the Near East some two thousand years before Christ. The Hyksos introduced the horse into Syria and Egypt some eighteen centuries before the Christian era. From Syria it was also introduced before the beginning of our era into Arabia where, as the Arabian horse, it has succeeded more
