After leaving the Beisân plain, the river passes through a narrow valley twelve miles long and two to three miles wide, with a raised table-land to the west, having a level averaging about 500 feet above the sea. The Beisân plain is full of springs of fresh water, some of which are thermal, but a large current of salt warm water flows down Wâdy Mâleh, at the north extremity of this fifth district. In the sixth district, the Dâmieh region, the valley again opens to a width of about three miles on the west, and five on the east of Jordan. The great block of the Kurn Sŭrtŭbeh here stands out like a bastion, on the west, 2400 feet above the river. Passing this mountain the seventh district is entered--a broad valley extending from near Fusâil to ’Osh el Ghŭrâb, north of Jericho. In this region the Ghôr itself is five miles broad, west of the river, and rather more on the east; the lower trench or Zor is also wider here and more distinctly separated from the Ghôr. A curious geographical feature of this region was also discovered by the Survey party. The great affluents of the Fâr’ah and ’Aujeh do not flow straight to Jordan, but turn south about a mile west of it, and each runs, for about six miles, nearly parallel with the river; thus the mouth of the Fâr’ah is actually to be found just where that of the next valley is shown on most maps. This curious feature was not discovered even by Captain Warren, and nothing more surprised me, in surveying the district, than the unsuspected parallel course of the streams. The whole of the valley in the seventh region is full of salt springs and salt marshes, but the Fâr’ah, flowing from the Ænon springs, is a perennial stream of fresh water. The eighth and last district is that of the plain of Jericho, which with the corresponding basin (Ghôr-es-Seisebân) east of Jordan, measures over eight miles north and south, and more than fourteen across, with Jordan about in the middle. The Zor is here about a mile wide, and some 200 feet below the broad plain of the Ghôr. To sum up shortly the regions thus enumerated. First we have the Huleh marshes; secondly, the basin of the Sea of Galilee; thirdly, the narrow gorge of Kaukab; fourthly, the plain of Beisân; fifthly, the narrow valley below the Bukei’a of Tûbâs; sixthly, the broader region of the Fâr’ah; seventhly, the wide Fusâil Valley; eighthly, the great basin of the Jericho plain; in short, four broad regions connected by two narrow ones, with a marshy lake and valley highest of all, suggestive, as a glance at the map will show, of a former chain of great lakes connected by a river, which have gradually dwindled in area till three small sheets of water alone remain, with the broad dry beds of two others, represented by the Beisân and Jericho basins. The question thus suggested of the original formation of this great chasm, is not only interesting in itself, but it has a direct bearing on that of the position of the Cities of the Plain.
