See!" Again a picture formed.

The sky was full of aircraft which rained down fire like flashes of lightning upon cities beneath.

From these cities leapt up other fires that destroyed the swift-travelling things above, so that they fell in numbers like gnats burned by a lamp.

Still more and more of them came till the cities crumbled away and the flashes that darted from them ceased to rush upwards.

The Sons of Wisdom were driven from the face of the earth.
Again the scene changed.
