A flash of lightning illuminated the startled faces of the five boys. With one accord they rushed into the hallway. It was a narrow place, heavy with dust, and their feet thudded heavily on the mouldy flooring.

Crash!

At the far end of the hall they had a glimpse of falling plaster that fell in a great heap to the floor. A dense cloud of dust arose and filled the narrow chamber.

“Run for your lives!” yelled Frank.

But no sooner were the words out of his mouth than there came a ripping, crackling sound from overhead. Immediately above them, a large part of the ceiling, disturbed no doubt by the vibrations of their feet as they ran into the hall, had given way. A wide crack that showed in the plaster quickly became wider, and then, with a terrific roar, half the hall ceiling came tumbling down upon the lads.

They were buried in dust and lathes and plaster that came upon them in such an avalanche that they were thrown to the floor. The splintering of wood and ominous crackling that followed, indicated that more of the ceiling was about to go, and then came a roar even louder than the first, as another avalanche of débris rolled down upon them.

Was the Polucca house falling in?

CHAPTER III

Empty Tool Boxes

When he was knocked off his feet by the impact of falling débris, Frank Hardy crouched down, protecting his head as well as possible, until the downfall was over. Although a great deal of rubbish descended, it was not heavy material and when at last the rain of plaster and splintered lathes had ceased Frank knew that he was uninjured, although he was almost buried in the heap and half smothered by the thick dust that rose all about him.
