Seven Pillars of Wisdom by T.E. Lawrence

To townsmen this garden was a memory of the world before we went mad with war and drove ourselves into the desert: to Auda there was an indecency of exhibition in the plant-richness, and he longed for an empty view. So we cut short our second night in paradise, and at two in the morning went on up the valley. It was pitch dark, the very stars in the sky being unable to cast light into the depths where we were wandering. To-night Auda was guide, and to make us sure of him he lifted up his voice in an interminable Tio, ho, ho' song of the Howeitat; an epic chanted on three bass notes, up and down, back and forward, in so round a voice that the words were indistinguishable.

After a little we thanked him for the singing, since the path went away to the left, and our long line followed his turn by the echoes of his voice rolling about the torn black cliffs in the moonlight.
