The mudflats were bone-dry and afforded perfect going. Our tyres left only a faint white scar across their velvet surface, as we twisted about the spacious smoothness at speed, skirting clumps of tamarisk and roaring along under the great sandstone crags. The drivers rejoiced for the first time in nine months, and flung forward abreast in a mad race. Their speedometers touched sixty-five; not bad for cars which had been months ploughing the desert with only such running repairs as the drivers had time and tools to give them.

Across the sandy neck from the first flat to the second we built a corduroy road of brushwood. When this was ready, the cars came steaming and hissing along it, dangerously fast to avoid getting stuck, rocking over hummocks in a style which looked fatal for springs. However, we knew it was nearly impossible to break a Rolls-Royce, and so were sorrier for the drivers, Thomas, Rolls and Sanderson. The jolts tore the steering-wheel from their grip, and left them breathless with bleeding hands after the crossing.
