We left Khanzyre late in the evening, that we might enjoy the coolness of the night air. We ascended for a short time, and then began to descend into the valley called Wady el Ahsa. It had now become dark, and this was, without exception, the most dangerous route I ever travelled in my life. The descent is steep, and there is no regular road over the smooth rocks, where the foot slips at every step. We had missed our way, and were obliged to alight from our horses, after many of us had suffered severe falls. Our Sheikh was the only horseman who would not alight from his mare, whose step, he declared, was as secure as his own. After a march of two hours and a half, we halted upon a narrow plain, on the declivity of the Wady, called El Derredje (Arabic), where we lighted a fire, and remained till day-break. August 7th.—In three quarters of an hour from Derredje, we reached the bottom of the valley. The Wady el Ahsa (Arabic), which takes its rise near the castle El Ahsa, or El Hassa, on the EL KERR [p.401] Syrian Hadj road, runs here in a deep and narrow bed of rocks, the banks of which are overgrown with Defle. There was more water in the rivulet than in any of those I had passed south of Zerka; the water was quite tepid, caused by a hot spring, which empties itself into the Ahsa from a side valley higher up the Wady. This forms the third hot spring on the east of the Dead sea, one being in the Wady Zerka Mayn, and another in the Wady Hammad. The valley of El Ahsa divides the district of Kerek from that of Djebal (plur. of Djebel), the ancient Gebalene. In the Ghor the river changes its name into that of Kerahy (Arabic), and is likewise called Szafye (Arabic). This name is found in all the maps of Arabia Petræa, but the course of the river is not from the south, as there laid down; Djebal also, instead of being laid down at the S.E. extremity of the lake, is improperly placed as beginning on the S.W. of it. The rock of the Wady el Ahsa is chiefly sand-stone, which is seldom met with to the N. of this valley; but it is very common in the southern mountains.
