But very soon the girls crept back.

“I don’t like sacrifices,” Jane said. So she and Anthea went and talked to the priest, who was no longer lying on his face, but sitting on the top step mopping his forehead with his robe, for it was a hot day.

“It’s a special sacrifice,” he said; “usually it’s only done on the justice days every five years and six years alternately.

But this today is because the City’s so upset by the odd noises from the sea, and the god inside the big mountain speaking with his thunder-voice. But all that’s happened so often before. If anything could make ME uneasy it wouldn’t be that.”

You know rats won’t stay on a ship that’s going to be wrecked. If anything horrible were going to happen to us, it’s my belief those Lemmings would know; and that may be why they’ve fought shy of us.”
