down the mudflats towards Mudowwara.
The cars were now at Guweira, in permanent camp. Gilman and Dowsett, with their crews and fifty Egyptian soldiers, had spent months in Wadi Itm, building, like engineers, a motor road through the gorge. It had been a great work, and was now in order to Guweira. So we took the Rolls tenders, filled them with spare tyres, petrol, and food for four days, and set off on our exploring trip.
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.
We lunched and rested, and then had another burst of speed, with a wild diversion in the middle when a gazelle was sighted over the flat, and two of the great cars lurched aside in unavailing chase.
At the end of this second flat, the Gaa of Disi, we had a rough mile to the third flat of Abu Sawana, across which we had a final glorious sprint of fifteen miles, over the mud and over the equally firm flint plains beyond.
