Three men were walking slowly along the causeway which led from the top of the hill down into the valley, but it was only the eldest, who walked in front of the other two, who gave any heed to the sky, the sea, the gulls, and the barren plain that lay silent at his feet. He stopped, and as soon as he did so, the others followed his example. The landscape below him seemed to rivet his gaze, and it justified the disapproval with which he gently shook his head, which was somewhat sunk into his beard. A narrow strip of desert stretched westward before him as far as the eye could reach, dividing two levels of water. Along this natural dyke a caravan was passing, and the elastic feet of the camels fell noiselessly on the road they trod. The leader, wrapped in his white mantle, seemed asleep, and the camel-drivers to be dreaming; the dull-colored eagles by the road-side did not stir at their approach. To the right of the stretch of flat coast along which the road ran from Syria to Egypt, lay the gloomy sea, overhung by grey clouds; to the left lay the desert, a strange and mysterious feature in the landscape, of which the eye could not see the end, either to the east or to the west, and which looked here like a stretch of snow, there like standing water, and again like a thicket of rushes.
