"Of course."

"It's a bully hiding-place," said Horace, "but how about food?"

"I've a whole storehouse here."

"And air?"

"None too good. I drove a length of iron pipe upwards to the surface of the ground. Just where it comes out I don't know. I never had a chance to look. It isn't much, but it's something."

"How much longer do you expect to stay here?" asked Horace.

"Not a minute longer than I can help. I'm clearing out to-night."

"To-night?"

"Just as soon as things quiet down, we start. It's our last chance. To-morrow the troops will march on, Liége will be put under regular German rule, patrols and sentries will be established and we'll be trapped. It's to-night or not at all. We have got to escape in the confusion of this last day's bombardment."

The boy thought a moment.
