On two sides Palestine is bordered by water. The Mediterranean Sea, extending along the western margin of the land, forms inlets for ships. Along the eastern boundary flows the Jordan, which takes its rise in the slopes of Mount Hermon, and runs in nearly a straight line from north to south. In the north the Jordan flows through the "Lake of the Harp" (_Kinnereth_, _Genesareth_, or Lake of Tiberias), and in the south this river is lost in the wonderful "Salt Sea." These two basins form likewise a strange contrast. The "Lake of the Harp" (also "Lake of Galilee") contains sweet water. In its depths fishes of various kinds disport themselves. On its fertile banks, the vine, the palm, the fig-tree, and other fruit-bearing trees are found to thrive. In the high temperature of this region, fruits arrive at their maturity a month earlier than on the mountain land. The Salt Sea or "The Sea of the Deep Basin" (_arabah_) produces a contrary effect, and has rightly been called the Dead Sea. In its waters no vertebrate animals can exist. The excessive quantities of salt, together with magnesia, and masses of asphalt contained in that sea, kill every living object. The atmosphere of this region is likewise impregnated with salt, and, as the adjacent land is covered with lime-pits, it forms a dreary desert. The oval-shaped border of the Dead Sea rises, in some parts, to a height of more than 1,300 feet above the water level, and being totally bare and barren, the entire district presents a most dismal aspect. Between the water-line and the mountain walls there are, however, some oases in which the balsam shrub thrives, and which, in regard to fertility, are not inferior to any spot on earth. Being situated near the centre of the western seaboard, this strip of land is exceedingly fruitful. But luxuriant as the vegetation of this place is, it is even surpassed by that of the oasis on the south-east corner of the Dead Sea. Here stood at one time the town of Zoar, which was noted as the city of palm-trees (Tamarah). This locality likewise favoured in former ages the growth of the balsam shrub. At a distance of five miles to the north-east, near the town of Beth-Haran, the famous balm of Gilead was found; but by the side of the Dead Sea miasmatic salt-marshes extend for a length of several miles. The shores of this sea and also of the sea of Galilee send forth thermal springs impregnated with sulphur, and these serve to cure various maladies.
