It would be superb to have the old factotum pulling away at his rope and fancying he was fulfilling his duty when the tongueless bell was swinging silently on its pivot.

Berry worked the tongue this way and that, but it was a difficult job. The inside of the bell was as dark as the inside of a wolf, to use a hunter’s simile; he had to feel everything, and the metal was terribly cold.

However, at last he managed to unhitch it. He deliberated what to do with it, now he had it. He put it in his pocket, and descended as quickly as was consistent with security.

“Off with the ladder,” was his first order.

“What are you going to do with it?” asked Millward, alluding to the rusty tongue which Berry exhibited.

“I think I shall leave it at the bottom of the turret. If I take it away they’ll know some one’s been up, but if we leave it here they’ll think it’s dropped down.”

“Let’s hope they will,” said Culverwell, dubiously.

“At any rate, I’ll chance it,” continued Berry. “So you fellows will be able to have a tall time to-morrow morning; we sha’n’t get called till half-past eight, at the earliest.”
