"If the gods are so wonderful why did they kill your other two children?" asked Miran sourly. "And why did they kill my Clansmen, and why did they smash my Bird? Why...?"

"Shut up!" said Green. "This is no time to cry about anything. We have to get out with whole hides. The philosophizing and tears can come later."

"Mennirox is an ungrateful god," muttered Miran. "After all I did for him, too."

Amra dried her tears and said, "How did you escape? I thought all the males who hadn't been killed in the wreck were speared?"

"Almost everybody was," replied Grizquetr. "But I crawled down into the hold and slipped through to a hiding place beneath one of the fish tanks, which had overturned. It was wet there, and there were dead fish nestling beside me. The savages did not find me, though doubtless they would have when they began salvaging. It was thinking about that that decided me to crawl back out on the other side of the 'roller away from the savages. I did so, and I found that I could belly my way through the grass growing on the edge. I almost died of fright, though, because I crawled head on into Miran. He was hiding there, too."

"I was thrown off the foredeck by the impact," interrupted the captain. "I should have broken every bone in my body, but I landed on a hull sail, which had come down and was lying on the starboard side, supported by the fallen mast. It was like falling into a hammock. From there I dropped into the grass and snaked along the very edge of the island. Several times I almost fell off, and I would have if I'd been a pound fatter, an inch wider. As it was...."

"Listen," said Grizquetr, breaking in. "This island is the wuru!"

"What do you mean?" said Green.

"While I was clinging to the edge of the island I thought I'd hang down over it and see if there was any place there to hide. There wasn't, because the underside of the island is one smooth sheet. I know, because I could see in the moonlight clear to the other side. It was smooth, smooth, like a slab of iron.

"And that's not all! You know how the grass on the plains hereabouts has been tall, uncut? Well, the grass just ahead of the edge was uncut. But the grass underneath the island was being cut off. Rather, it was vanishing! The top of the grass was just disappearing into air! Only a lawn of grass about an inch high was left!"
