This storm lasted for eighteen minutes, and then leaped forward from us as suddenly as it had come. Our party was scattered over a square mile or more, and before we could rally, while we, our clothes and our camels were yet smothered in dust, yellow and heavy with it from head to foot, down burst torrents of thick rain and muddied us to the skin. The valley began to run in plashes of water, and Dakhil-Allah urged us across it quickly. The wind chopped once more, this time to the north, and the rain came driving before it in harsh sheets of spray. It beat through our woollen cloaks in a moment, and moulded them and our shirts to our bodies, and chilled us to the bone.
