"Get your electroscopes out and spot him a hundred yards from this truck."
"Very well, Doctor."
he men with the instruments spread out along the path of the borer. Briskly they rubbed their sleeves with the rubber rods and charged their instruments. Almost as fast as they charged them, the tiny bits of gold-leaf collapsed together. Presently the man on the end of the line shouted.
"Maximum discharge!" he cried.
Dr. Bird looked around. Every man stood ready at his post. The next man signalled that the borer was under him. Carnes felt himself trembling. He did not know what the doctor was about to do, but he felt that the fate of America hung in the balance. Whether it remained free or became the slave of Soviet Russia would quickly be decided.
Slowly the borer made its way forward. With a pale face, Jones signalled the news that it had reached the point the doctor had indicated. Dr. Bird raised his hand.
"Power!" he cried.
The electrician closed a switch and power surged through the cables around the bar. The earth rocked and quivered. A hundred yards east of the bar a flash of intolerable red light sprang from the ground with a roar like that of Niagara. Toward the bar it moved with gathering momentum.
