Granite and gneiss, overlaid with hard dark sandstone and masses of secondary limestone, form as it were the skeleton of the country. Here and there, at Carmel and Gerizim, patches of the tertiary nummulite of Egypt make their appearance, and in the plains of Megiddo and the coast, as well as in the "Ghor" or valley of the Jordan, there is rich alluvial soil. But elsewhere all is barren or nearly so, cultivation being possible only by terracing the cliffs, and bringing the soil up to them from the plains below with slow and painful labour. It has often been said that Palestine was more widely cultivated in ancient times than it is to-day. But if so, this was only because a larger area of the cultivable ground was tilled. The plains of the coast, which are now given over to malaria and Beduin thieves, were doubtless thickly populated and well sown. But of ground actually fit for cultivation there could not have been a larger amount than there is at present. It was not in any way a well-wooded land. On the slopes of the Lebanon and of Carmel, it is true, there were forests of cedar-trees, a few of which still survive, and the Assyrian kings more than once speak of cutting them down or using them in their buildings at Nineveh. But south of the Lebanon forest trees were scarce; the terebinth was so unfamiliar a sight in the landscape as to become an object of worship or a road-side mark. Even the palm grew only on the sea-coast or in the valley of the Jordan, and the tamarisk and sycamore were hardly more than shrubs. Nevertheless when the Israelites first entered Canaan, it was in truth a land "flowing with milk and honey." Goats abounded on the hills, and the bee of Palestine, though fierce, is still famous for its honey-producing powers. The Perizzites or "fellahin" industriously tilled the fields, and high-walled cities stood on the mountain as well as on the plain. The highlands, however, were deficient in water. A few streams fall into the sea south of Carmel, but except in the spring, when they have been swollen by the rains, there is but little water in them. The Kishon, which irrigates the plain of Megiddo, is a more important river, but it too is little more than a mountain stream. In fact, the Jordan is the only river in the true sense of the word which Palestine possesses. Rising to the north of the waters of Merom, now called Lake Hûleh, it flows first into the Lake of Tiberias, and then through a long deep valley into the Dead Sea. Here at a depth of 1293 feet below the level of the sea it is swallowed up and lost; the sea has no outlet, and parts with its stagnant waters through evaporation alone. The evaporation has made it intensely salt, and its shores are consequently for the most part the picture of death.
