The cloud was nearly as high as the hill. While it approached, two dust-spouts, tight and symmetrical chimneys, advanced, one on the right and one on the left of its front. Dakhil-Allah responsibly looked ahead and to each side for shelter, but saw none. He warned me that the storm would be heavy.

When it got near, the wind, which had been scorching our faces with its hot breathlessness, changed suddenly; and, after waiting a moment, blew bitter cold and damp upon our backs. It also increased greatly in violence, and at the same time the sun disappeared, blotted out by thick rags of yellow air over our heads. We stood in a horrible light, ochreous and fitful. The brown wall of cloud from the hills was now very near, rushing changelessly upon us with a loud grinding sound. Three minutes later it struck, wrapping about us a blanket of dust and stinging grains of sand, twisting and turning in violent eddies, and yet advancing eastward at the speed of a strong gale.
