The ranks behind could not see where they were going, which was difficult for them, as the hillocks came closer together, and the riverbed slit into a maze of shallow channels, the work of partial floods year after year. Before we gained the middle of the valley everything was overgrown by brushwood, which sprouted sideways from the mounds and laced one to another with tangled twigs as dry, dusty and brittle as old bone. We tucked in the streamers of our gaudy saddlebags, to prevent their being jerked off by the bushes, drew cloaks tight over our clothes, bent our heads down to guard our eyes and crashed through like a storm amongst reeds. The dust was blinding and choking, and the snapping of the branches, grumbles of the camels, shouts and laughter of the men, made a rare adventure.
