Isbel nodded. She said nothing; she was listening. Then she said: "They will have been talking, all sitting round as they were to-day. Sru will have been making plans to come here and kill us. Then when all their minds went together like men with spears they shouted like that and jumped to their feet and started."

She spoke like a person who was watching it all in some magic glass, slowly and in a dreamy manner and with a detachment as though what she were viewing had nothing to do with them.

"They'll start more before I have done with them," said Floyd viciously.

The events of the day, the tension of waiting, and that shout, cruel as a barbed spear coming out of the night, had raised the fierce fighting spirit of his race, a spirit all the more potent and terrible from the underlying sobriety that tempers its fierceness and levity.

"It's funny to think we may be knocked out before the sun rises again," said he. "What do you think happens to a man when he's dead, Isbel?"

"I don't know. It is, I think, all the same as before he is born. He doesn't know."

"That's what I have often thought myself," said he. "Look! What is that?"

Away toward the far end of the reef they saw moving points upon the coral. Huge insects seemed crawling here and there, aimlessly at first, and now approaching nearer.

"They are coming," said Floyd, seizing a rifle. "They are spreading themselves out, and that confounded coral gives them good sheltering places. We must stop them if possible."

He stood up, and, putting the rifle to his shoulder, aimed it at the nearest moving spot and fired. He continued blazing away till the chambers were empty. The movement ceased, but almost immediately it recommenced, and now they could see the brown figures crouching and crawling, spread out fanwise, taking cover at every projection, and always advancing closer.
