“The old mill's got under way,” cried Shep. “She's going to tune up for Kingdom Come.”

A furious head of water was rushing along the race; the great wheel creaked and swung over, and with a shudder the old mill awoke from its long sleep. The cogs clenched their teeth, the shafting shook and rattled, the stones whirled merrily round.

“Now she goes it!” cried Shep, as the humming increased to a tremor, and the tremor to a wild, unsteady din, till the timbers shook and the bolts and windows rattled. “I just wish father could hear them old stones hum.”

“Oh, this is awful!” said Dorothy. She was shivering and sick with terror at this unseemly midnight revelry of her grandfather's old mill. It was as if it had awakened in a fit of delirium, and given itself up to a wild travesty of its years of peaceful work.

Shep was creeping about in the darkness.

“Look here! We've got to stop this clatter somehow. The stones are hot now. The whole thing'll burn up like tinder if we can't chock her wheels.”

“Shep! Does thee mean it?”

“Thee'll see if I don't. Thee won't need any lantern either.”

“Can't we break away the race?”

“Oh, there's a way to stop it. There's the tip-trough, but it's downstairs and we can't reach the pole.”
