“So ’tis,” assented Culverwell.

“Then I must get up to the ledge with a ladder, and then pull it up after me.”

“You’re a plucky beggar!” exclaimed Millward, in admiration. “Shouldn’t we have a jolly snooze in the morning if you could stop that old bell’s jaw!”

“I will, too,” said Berry. “There must be a ladder somewhere about.”

“There’s the one John uses to clean the outside of the windows,” suggested Millward, “but it isn’t long enough.”

“It may do,” said Berry. “Come along, let’s get hold of it. This is just the time; it’s dark, and ’tisn’t tea-time for half an hour.”

It was just five o’clock and nearly every boy was indoors; few cared for sliding on a worn slide in the dark, and a game was out of the question. So the three boys had small fear of being discovered as they prowled about in search of John’s ladder.

That worthy was having his tea, and was not likely to be disturbed by any noise, for he was stone deaf. The boys hauled out his ladder almost from under his nose without his hearing a sound. Culverwell kept “cave” while Millward held the ladder for Berry to ascend.

It was a plucky if not perilous feat to attempt in the dark. But Berry was abounding in pluck, and the spirit of the adventure made him keep his nerve. He soon found himself on the ledge, and managed to haul up the ladder after him. It was an assistance instead of an incumbrance in crossing the roof, and he soon was within a dozen feet of the turret.

The boys below anxiously waited for his reappearance. But he had a job before him. His idea was to unship the tongue of the bell. He had a glorious reward if he could succeed, for John would never know if the bell rang or not!
