John was bringing them down faster than ever, and Revel must needs split up his small force even more, sending miners to each wreck to catch as many entities as possible. Many spheres of gold managed to rise into the sky, where they found sanctuary in other saucers: some zanphs went scooting for shelter in the rocks and bushes, but most stayed to fight and die. He yearned to check his forces back on the hill, those protecting John's machine, and the men who still fought the gunmen in the upper end of the valley. But he dared not take his encouraging presence from the miners here. A button came swooping to earth not three yards from him, spraying him with clods of dirt, unbalancing him by the shock; a zanph gained purchase on his shoulder and tore flesh and sinew and muscle so that his left arm lost much of its strength and cunning. He killed it with the pick handle and struggled on into a mob of the brutes, panting now and blinking blood from his eyes. Of his original two hundred, less than seventy remained. Still he dared not draw any from the protective ring. Where were the rebels that Vorl and Sesker and the others had gone to rouse? Probably raiding mansions miles away. He should have told them ... oh, well. Surely the concentration of noise and buttons and gods above the valley would bring them soon. A moment's respite allowed him to look at the sky. It was lightening a little for the early dawn, and the buttons were less bold; most of them hovered near the horizon, only an occasional one bravely sailing in at a terrific speed to make a try at bombing the valley. John, perhaps with Nirea helping him, had managed to bring down every one so far. But John and Revel would run out of luck some time, as every man does; then John would miss, Revel's arm would fail, and they would all die. * * * * * Even as he lowered his head a gargantuan blast shook the world below him. He fell into a mob of zanphs, who were fortunately so demoralized by the explosion that they ignored him till he could gain his feet and begin to murder them once more. From the tail of his eye he saw a mushroom cloud lowering just beyond the hill; he flicked his gaze at the crest where his men had been stationed to guard the _antiforcescreenthrower_--no human form showed against the gray sky. The blast had hurled them to dust, together with every tree on the skyline. Finally--the gods knew how long he had fought--he found with amazement that no more foes were in sight. The buttons that had fallen were all cleaned out. Zanphs lay thick in heaps and lines, emptied sacks of globes dotted the bloody grass. He listened for the sound of firing from the upper valley; yes, there were still isolated shots. His forces there still held, then. He glanced again at the sky. No buttons in range. They were giving John a respite--or was it a trick? Revel's tired mind wondered if John and Nirea were dead, and the gods playing with him this way....
