Next day, in the early heat, we were near Guweira, comfortably crossing the sanded plain of restful pink with its grey-green undergrowth, when there came a droning through the air. Quickly we drove the camels off the open road into the bush-speckled ground, where their irregular colouring would not be marked by the enemy airmen; for the loads of blasting gelatine, my favourite and most powerful explosive, and the many ammonal-filled shells of the Stokes’ gun would be ill neighbours in a bombing raid. We waited there, soberly, in the saddle while our camels grazed the little which was worth eating in the scrub, until the aeroplane had circled twice about the rock of Guweira in front of us, and planted three loud bombs.

We collected our caravan again on the path and paced gently into camp. Guweira was thronged with life, and a mart for the Howeitat of both hills and highlands. As far as the eye reached the plain was softly moving with herded camels, whose multitude drained the near water-holes each morning before dawn, so that late risers must travel many miles to drink.
