There was a large, round beam of wood, overhead, slowly revolving.

There were wheels upon it in different parts, with straps passing around these wheels, and also around other wheels connected with the machines below.
Oliver saw Jonas walk to a man who was writing at a desk in the corner of a room, and say something to him.

Oliver could not hear what it was.
Jonas pointed, while he was talking to the man, to the great bundle of wool.

Presently the man came and took the bundle of wool, and dragged it off to one of the machines, which was not in motion.

He called a girl to come and tend it.
At one end of the machine was a broad band of cloth, passing around two rollers.
