Figure of Three

Figure of Three locks stonework

I think that you can see that John Smeaton, engineer on this stretch of the Calder & Hebble Navigation, had previously worked on lighthouses. This 250 year-old stonework withstood the ravages of the Storm Ciara floods in February last year, but the spillway and the island were scoured away. A £3 million repair project took a year to complete, delayed by the coronavirus outbreak.

underpass

On our school cross country, my friend John and I used to jog – or more probably saunter – through this echoey underpass beneath the railway. As we were wearing our football kit we could imagine that it would be something like this in the tunnel at Wembley on Cup Final day. Not that we were keen on football: for me 90 minutes wandering along the school cross country route was preferable to running up and down the pitch. We knew all the short cuts, so we didn’t have to run all the way.

Healey Mills footbridge over the Calder

We cross the Calder here, at Healey Mills, but at that time there was a riveted steel footbridge, now replaced by this box girder bridge.

Healey Mills

Our cross country route took us down the hill behind the gasworks and through the hamlet of Healey Mills. At that time people lived in this small terrace at the entrance to the mill yard.

We sometimes had a bit extra to our route because the school playing fields were another quarter of a mile from the school in South Ossett.

Sketching Smeaton

SmeatonSmeatonWriting my nature diary for the January edition of the Dalesman magazine, I got sidetracked by the story of John Smeaton (1724-1792), ‘the father of civil engineering’. He only has a walk-on part in my article, where he described the rock in Coxley Quarry as ‘the best Blue Stone’ he had ever seen (I’ve come up with a theory of why he described the buff sandstone in the quarry as ‘Blue Stone’).

He visited the quarry in 1760 when he was acting as superintendent engineer on what would become the Calder and Hebble Navigation. The year before he had completed the construction of the Eddystone Lighthouse, which he designed to have the proportions of the trunk of an oak tree.

SmeatonHe’d also recently been awarded a medal by the Royal Society for his work on the mechanics of waterwheels and windmills. His enquiries into the relationship between pressure and velocity for objects moving in air led to a formula for calculating lift that the Wright brothers used in designing their aircraft.

Coxley QuarryI wanted to draw Smeaton looking suitably dynamic for my article but for the main illustration we’re going for an acrylic on board painting that I made on location twenty years ago in 1996.
