"If they were trying to smack us, they could stand a refresher course in pin-pointing ... let's get the thrower out here fast. Too many saucers directly above us for comfort."

"There went another quarter of Dolfya," said Rack. "What power they have!"

"You'll see their power come plummeting to earth if I can work the machine," said John urgently. "Bring it out!"

The miners hauled it out, a titanic job even when men pressed tight against men and uncounted hands lifted the great burden. John showed them where to put it on the rock shelf. "Hoist me up on top," he clipped. It was done. "Now watch."

Revel stared at the sky till his eyes began to ache. At last John shouted, "I'm ready, but listen—I see a lot of torches coming up the valley, and the men holding 'em are mounted!"

"Our rebels, likely," said Jerran.

"Send men to meet them," yelled Revel. "They might be gentry. Pickmen and those with guns. Fast!"

"Okay, son," said John then, "watch the buttons just over us."

All heads tilted. A strange clanking came from the great box, a beam of thick-looking purple light lanced upward from the gun-like projection on top and fingered out toward the buttons. "Be ready," called John from the top of the machine. "This'll nullify the diamond rays for a few minutes, but then the things will be able to rise again. Your men must go out and break into the buttons before the globes can get 'em up!"

Revel issued his orders quickly. The purple light had now touched a button, which wavered from its fixed position, then as the beam caught it fully, dropped like a flung stone. Hundreds of voices bellowed the rebels' joy. Half a hundred miners leaped off into the night to attack the fallen ship, which struck the earth some distance up the valley with a shattering crash.
