Walter searched carefully, but in vain, for any lock, bolt, or other fastening.

"If I only had a sledge, or hammer, and cold chisel, I'd cut these grates off, short notice."

"I saw a crowbar outside, among some garden tools," said Ned.

"Get it; that's the thing."

Walter plied the bar upon the grates till the sparks flew from the iron, and the sweat dropped from his forehead; but it resisted his efforts.

"Let me spell you, Wal."

"Try the wood below, Ned."

"It is oak, and studded with iron; but I'll try it."

After a few blows, the door flew open of its own accord. Ned, by a random stroke, had moved the spring.

"That's good luck, Ned. Go ahead."
