The Jebel es Zubleh is a mountain fifty miles and more in length, and so narrow that its tracery on the map gives it a likeness to a caterpillar crawling from the south to the north. Standing on its red-and-white cliffs, and looking off under the path of the rising sun, one sees only the Desert of Arabia, where the east winds, so hateful to vinegrowers of Jericho, have kept their playgrounds since the beginning. Its feet are well covered by sands tossed from the Euphrates, there to lie, for the mountain is a wall to the pasture-lands of Moab and Ammon on the west--lands which else had been of the desert a part.
