A little above Wasta we came to Kharma, a tiny settlement with rich palm-groves, where a tributary ran in from the north. Beyond Kharma the valley widened somewhat, to an average of perhaps four hundred yards, with a bed of fine shingle and sand, laid very smooth by the winter rains. The walls were of bare red and black rock, whose edges and ridges were sharp as knife blades, and reflected the sun like metal. They made the freshness of the trees and grass seem luxurious. We now saw parties of Feisal’s soldiers, and grazing herds of their saddle camels. Before we reached Hamra every nook in the rocks or clump of trees was a bivouac. They cried cheery greetings to Tafas, who came to life again, waving back and calling to them, while he pressed on quickly to end his duty towards me.
