the Priory. Priory Water Mill was in use from the medieval period until 1876, and a large lake called the Canch was formed in 1820, by constructing a dam across the leat which fed it. The Canch gradually became polluted, and was filled in when milling ceased in 1876. The buildings were utilised by William Bramer and Sons for their business of making chairs until they burnt down in 1912, and the site has more recently become the location of a sensory garden. Three channels continue under Priorswell Road through separate bridges, cross Bracebridge field, and join up again near the old High Hoe Road bridge. Below Worksop Continuing under the new High Hoe Road bridge, the river passes the derelict Grade II listed Italianate pumping station built in 1881 to pump sewage away from Worksop, before passing under the Chesterfield Canal again, through a 3-arched aqueduct. A feeder, which is at a higher level, passes under the canal through a culvert, and joins the canal through a sluice just below Kilton lock, after which the river and canal run parallel, until they pass through separate arches of a nine-arched viaduct which carries the Sheffield to Lincoln Railway line, opened in 1849. The river then follows a winding course through the estate of Osberton Hall and the village of Scofton, turning north to skirt the western edge of Ranby. Ranby Chequer Bridge marks the point at which the river, having flowed eastwards for most of its course, turns to the north west. The bridge itself can be reached from Ranby village by a footpath which runs along the central reservation of the A1 road for a short distance. The next major crossing is the B6045 at Hodsock Red Bridge, its three arches constructed of red bricks with stone lining, after which an early 19th-century Grade II listed twin-arched bridge carries the drive to Hodsock Priory over the river. Then comes the A634 to the west of Blyth. The bridge here has three arches, was built for William Mellish of Blyth Hall around 1770, probably by the architect and bridge designer John Carr of York, and is a Grade I listed structure. Despite its age, it is called Blyth New Bridge, to distinguish it from Blyth Old Bridge which carries the same road over Oldcotes Dyke, a little further to the west. Before the next crossing of the B6045, the river
