"Just to north of that gash—that wady, or gully, making down to the beach. You see it, eh?"

Slowly the French ace swept the glasses along the surf-foamed fringes of that desolation. Across the lenses no tree flung its green promise of shade. No house, no hut was visible. Not even a patch of grass could be discerned. The African coast lay stretched out in ivory nakedness, clean, bare, swept and garnished by simooms, by cruel heat, by the beatings of surf eternal.

Back of it extended an iron hinterland, savage with desert spaces of sun-baked, wrinkled earth and sand here and there leprously mottled with white patches of salt and with what the Arabs call sabkhàh, or sheets of gypsum. The setting sun painted all this horror of desolation with strange rose and orange hues, with umbers and pale purples that for a moment reminded the Master of the sunset he had witnessed from the windows of Niss'rosh, the night his great plan had come to him. Only eight days ago, that night had been; it seemed eight years!

"I see them," the Master answered. "And the green flag—the flag of the Prophet—"

"The flag, oui, mon capitaine! There are many men, but—"
