"Thank you," breathed Grizquetr in all sincerity.
"Here's what I'll do," said Green. "I'll roll this island back and forth until the soldiers are thoroughly panicky and seasick. And the walls around the cave are tumbled down. Then we'll lower to earth again and give the rats a chance to desert the ship. But we're no sinking ship, not us. After everybody that's able has fled to the plains, we'll take off at top speed for Estorya."
Fascinated, the boy watched the screens and saw the soldiers run off into the early morning light, yelling, their eyes and mouths bulging with horror. Some, wounded, crawled off.
"I feel sorry for them," said Green, "but somebody's got to get hurt before this is over and I'd rather it wasn't us."
He pointed to the 'scopes, which still indicated the ring of towers.
"As long as this island was on automatic it couldn't pass those inhibitories. But I've by-passed that with this switch. Now, we go ahead, and not over the towers, as we could easily do, but through them. I think we've got the weight behind us."
There was a slight shock, the rooms trembled, then the towers before them were gone and they were speeding across the plain. Minute by minute Green increased their rate, until he thought they must be making about a hundred and twenty-five miles an hour.
"Those dials are probably telling me my speed," he said to Grizquetr. "But I can't read their alphabet or numerical system. It doesn't matter."
He laughed as he watched 'rollers wheel hard aport or hard to starboard in a frenzy to get out of their way. The rails and ratlines were lined with white faces, like rags of terror fluttering in the breeze of the island's passage.
"If there were time to send a message, I imagine we'd encounter the whole Estoryan fleet," said Green. "What a battle that would be! Rather, what a massacre, for this craft is built for eating up whole navies."
