“What is it you’ve fallen into？” asked Scrubb.
“It‘s a kind of trench， or it might be a kind of sunken lane or something，” said Jill. “It runs quite straight.”
“Yes， by Jove，” said Scrubb. “And it runs due north！ I wonderis it a sort of road？ If it was， we’d be out of this infernal wind down there. Is there a lot of snow at the bottom？”
“Hardly any. It all blows over the top， I suppose.”
“What happens further on？”
“Half a sec. I‘ll go and see，” said Jill. She got up and walked along the trench； but before she had gone far， it turned sharply to the right. She shouted this information back to the others.
“What’s round the corner？” asked Scrubb.
Now it happened that Jill had the same feeling about twisty passages and dark places underground， or even nearly underground， that Scrubb had about the edges of cliffs. She had no intention of going round that corner alone； especially when she heard Puddleglum bawling out from behind her：
“Be careful， Pole. It‘s just the sort of place that might lead to a dragon’s cave. And in a giant country， there might be giant earth.worms or giant beetles.”
“I don‘t think it goes anywhere much，” said Jill， coming hastily back.
