When we restarted, an hour’s mad race in the dusk brought us to the end of the Tehama, and to the foot of a low range of rock and sand. A month ago, coming from Hamra, we had passed south of this: now we crossed it, going up Wadi Agida, a narrow, winding, sandy valley between the hills. Because it had run in flood a few days earlier, the going was firm for our panting camels; but the ascent was steep and we had to take it at walking pace. This pleased me, but so angered Abd el Kerim, that when, in a short hour, we reached the watershed he thrust his mount forward again and led us at breakneck speed down hill in the yielding night (a fair road, fortunately, with sand and pebbles underfoot) for half an hour, when the land flattened out, and we came to the outlying plantations of Nakhl Mubarak, chief date-gardens of the southern Juheina.
