Night came down, and the valley became a mind-landscape. The invisible cliffs boded as presences; imagination tried to piece out the plan of their battlements by tracing the dark pattern they cut in the canopy of stars. The blackness in the depth was very real⁠—it was a night to despair of movement. We felt only our camels’ labour, as hour after hour monotonously and smoothly they shouldered their puny way along the unfenced level, with the wall in front no nearer and the wall behind no further than at first.

About nine at night we were before the pit in which lay the water and our old camp. We knew its place because the deep darkness there grew humidly darker. We turned our camels to the right and advanced towards the rock, which reared its crested domes so high over us that the ropes of our headcloths slipped back round our necks as we stared up. Surely if we stretched out even our camel-sticks in front of us we should touch the facing walls: yet for many paces more we crept in under their horns.
