Ross read it with a sinking heart. Los Angeles! A city of two million people, destroyed! Then it was Horta who had wiped out Nagasaki!

Moore pounced on that thought. "Nagasaki, then Los Angeles!" he muttered.

Ross turned to Artana. "Any other news?"

Artana shook his head. "No. But I have a plan. You know that when the rains come we store them in the great reservoirs, so that our under-world may not be flooded. Then why not loose the waters in the reservoirs, and flood the caverns?"

Ross stared in admiration. But he slowly shook his head. "You'd have to kill half your people, Artana, just to dispose of Horta."

"But," argued Artana desperately, "Horta will destroy half our people himself, to seize the Kingdom. And he will destroy the Earth folk, too!"

Moore spoke up. "The reservoirs are full?"

"No," admitted Artana. "The rains have not been heavy. The reservoirs are but half full." He sighed. "Horta might escape the flood."

"That's no good, then," Ross said emphatically. "Tell you what, Moore and I will go and scout the Cavern on foot. We may be able to get near enough to the ray works to smash 'em."

"You would die," Artana said somberly. "Horta guards his Cavern well."
