"I rather imagine they have gotten away as fast as they could after the Germans began blowing down the tottering walls. Those fellows we saw back there in the tunnel were possibly trying to get away by that route," replied David. "I intended bringing you here when we left the cellar where the rats were. I thought the way was clear."

"How did you happen to be there?" asked Ned.

"I got tired of being a prisoner," answered David. "Naturally, when the chance offered, I just slipped into the passage and started. I counted my steps to the end and found I must go the other way. When I had reached the cellar where you were I was exploring it when I heard the noise overhead. I just stayed in the dark until you made a light."

"Then you thought you'd help us out?" asked Harry.

"Yes," was the reply. "I felt that you needed a guide, and I had to do one good turn a day, you know. I thought that would be one."

"Sure, we know," Harry stated in a low voice. "I guess that was pretty nearly three good turns, wasn't it, Ned?"

"We'll count it as three, anyhow," responded Ned heartily.

"Now, you're hungry," interrupted David, rather loath to hear his own praises. "Come over this way and we'll see what we can find."

As David had predicted, the boys found a smaller room opening off the large one in which they were gathered. There was a miscellaneous collection of articles comprising food, ammunition, arms and many other things. They at once attacked the food supply.

Harry gleefully announced the discovery of a can of beef from Chicago, while Jack went into ecstacies over a can of beans.
