We had the accustomed calm run to Jidda, in the delightful Red Sea climate, never too hot while the ship was moving. By day we lay in shadow; and for great part of the glorious nights we would tramp up and down the wet decks under the stars in the steaming breath of the southern wind. But when at last we anchored in the outer harbour, off the white town hung between the blazing sky and its reflection in the mirage which swept and rolled over the wide lagoon, then the heat of Arabia came out like a drawn sword and struck us speechless. It was midday; and the noon sun in the East, like moonlight, put to sleep the colours. There were only lights and shadows, the white houses and black gaps of streets: in front, the pallid lustre of the haze shimmering upon the inner harbour: behind, the dazzle of league after league of featureless sand, running up to an edge of low hills, faintly suggested in the far away mist of heat.
