“ Thus the Touareg call themselves, from the veil or tagilmus which hides their fierce Berber faces from all eyes. Coralie Smith, however, appeared not to hear the warning; she gazed down the rocky slope at the valley beyond, her blue eyes bright and eager. Beside her the Touareg's eyes smote sharply from the slit of his dark blue veil and headcloth; his two slaves, veiled and armed like himself, followed his uneasy glances. One would have said that the white woman was less afraid than were these three riders of the secret tribe. ”
