Banks stayed on for another couple of hours, plodding about the building, examining doors, the extinct forges and furnaces, looking at the bands of the huge lathes, and displaying a curious kind of energy, as by means of a small bull’s-eye lantern he peered in and out of all sorts of out-of-the-way places.

“There’s no knowing what games Master Sim might try on,” he remarked to himself; “blowings up and cutting bands, and putting powther in the furnace holes; he’s shack enew for ought, and I dessay some on ’em will be stupid enough to side wi’ him. What’s that?”

He stopped and listened, for it seemed to him that he had heard a noise below him in the ground floor.

The sound was not repeated, so he went on cautiously through the great black workshop, with its weird assemblage of shafts, cranks, and bands, looking, in the fitful gleams cast by the lantern, like a torture-chamber in the fabled Pandemonium.

A stranger would have tripped and fallen a dozen times over the metal-cumbered floor; but every inch and every piece of machinery was so familiar to the foreman that he could have gone about the place blindfold, even as he did once or twice in the dark when he closed his bull’s-eye lantern, thinking he heard a noise.

All seemed right in this workshop, so he descended to the foundry, going over it and amongst the furnaces, now growing cold.

Then he threaded his way amongst the sunken moulds for castings; looked up at the cranes, paused before the massive crucibles used for melting bell-metal or ingots for the great steel bells, and ended by stopping again to listen.

“I’ll sweer I heerd a noise,” he muttered, taking a short constable’s staff from his pocket, and twisting its stout leather thong round his wrist. “It will be strange and awkward for somebody if I find him playing any of his tricks here.”

He went cautiously on tip-toe in the direction from which the noise had seemed to come, going up a short ladder to a raised portion of the foundry, which formed an open floor where lighter work was done.

He advanced very cautiously in the dark, holding his staff ready to deliver a blow, or guard his head, and the next minute there was the sound of some tool being moved on a bench, and then something alighted at his feet, setting up a soft purring and beginning to rub up against his legs.
