Theories put through the mill

Some beautiful stone troughs that stand in the garden of a reader who lives near Durham

I received some wonderful images of stone troughs from a reader who says: “I enjoyed your article on stone troughs as I have been puzzling over how on earth they were made, by whom, and who paid/got rewarded for making them with no more than manual tools. We have six such troughs of various sizes…We brought one small one from Durham, the rest were on site when we came here, origins unknown.”

As the pictures show, they make super containers for plants, flowers and herbs and nestle naturally into their surroundings, far more at home than a modern equivalent, don’t you think?

I’ve also been contacted about the huge millstone on the moor above Kildale. Reader John Buckworth got in touch a few weeks ago because he had been pondering about the massive, unfinished stone for more than 50 years. It has been chiselled out on one side, but left unfinished on the other, and had been abandoned far from any mill that would have been its ultimate destination. Why was it never finished or moved?

Mick Garratt, who blogs about his travels around the North York Moors, has wondered for years about the baffling millstone. He contacted me to discuss his theories and hopes someone reading this might shed more light upon the mystery.

“I’ve been really curious about that unfinished millstone too! I’ve written about it a few times on my blog and speculated some of my thoughts, but I still have so many questions that haven’t been answered,” he says.

On his blog, Mick mentions that in the 18th century there were two mills in Kildale. The first started life as a fulling mill, a process which thickened and matted together wool fibres, but once the wool industry declined the mill was converted into a bleaching mill to whiten linen cloth. The other mill was ‘the first recorded corn mill in Cleveland’, with the earliest record dating it to 1262, and another stating that it ‘was totally destroyed by a great inundation in 1321’ (A History of the County of York North Riding, Volume 2, ed. William Page, 1923). The corn mill was located near Old Meggison waterfall on the River Leven, north of Kildale village, while the bleaching mill was further down the valley, just below the current ‘Bleach Mill Farm’. On the night of 21st July 1840, the corn mill was wiped out and the bleaching mill severely damaged when, according to Bulmer’s History and Directory of North Yorkshire (1890), ‘Two artificial lakes or fish ponds, which added greatly to the charms of this picturesque vale, unable to bear the pressure of the water which the flood poured into the ponds, were completely swept away, and very considerable damage done by the water.’

Mick suggests: “Maybe the millstone was destined for the corn mill in Kildale but the flood of 1840 caused its manufacture to be abandoned. Purely a guess of course.”

Mick has another suggestion relating to the quality of the stone. “The North York Moors Historic Environment Record dates it to ‘post medieval’, which is any time between 1540 and 1799. The bedrock at this location is recorded as ‘undifferentiated sandstone, siltstone and mudstone’, none of which make particularly good millstones, but probably good enough for grinding proggin (cattle food). At Rievaulx, French burrstone (a sturdy limestone) was used for grinding wheat for flour, and millstone grit from the Derbyshire Peaks for proggin. Our unfinished millstone points then to a poor quality…Perhaps that’s the reason it was abandoned…perhaps a flaw was found.”

Mick also describes the method of carving a stone of sufficient quality to grind fine flour: “Once the millstone is shaped and transported to the mill, it would have to be finally dressed. The miller would ensure the grinding face was flat by proving it with a staff smeared with red rudd (a soft red stone collected from riverbeds and often used to colour front steps of cottages). Next, furrows or grooves would have to be chiselled out using a mill bill or pick. Furrows must be of the correct depth with a straight and sloping side. They act as scissors with those on the top stone during the grinding.”

Solid as a rock

What happens when you suddenly pay attention to something that has not been on your radar before? That thing starts popping up everywhere! A couple of weeks ago I mentioned I’d spotted an old stone trough in the garden of a house near York that piqued my attention. Since then, I have seen them all over the place, in gardens, on roadsides, on footpaths and in fields. Clearly, the stonemasons of North Yorkshire were kept very busy a few centuries ago.

I posed a few questions in the hope that a knowledgeable reader would help me flesh out the history of these troughs. Stan Willis is that knowledgeable reader: “I was fascinated to read your article on stone troughs…The trough would certainly have been cut from a solid piece of rock. To cut a rock that size out of a quarry would have been an achievement in itself. Then it would be to square up before any cutting out was done. It would be dragged to its intended site. The mason wouldn’t risk many weeks of chipping out before transport in case the finished article broke on the final journey. Pickaxes would not be used to cut out the trough…The main cutting would be done with a hammer and cold chisel, a laborious task which probably took several weeks.”

The one pictured with my column was between five and six feet long, about two to three feet wide and almost the same in depth. Stan informed me that such a piece would have been transported on wooden rollers pulled by horses, and that it was likely a drinking trough for large livestock.

He added: “I had the privilege to meet a man from Barnard Castle who probably cut out the last one in the area 50 years ago. He also ran a haulage business; I think is name was Marwood.”

Gurli Svith, who contacted me all the way from Denmark, reads my columns online. She said: “When I saw the picture of a trough, my first thought was ‘The Curse of the Golden Trough’, written by your father.” Gurli was referring to the 5th book in Dad’s Inspector Montague Pluke series, where the eccentric inspector’s hobby, between solving murders, is to seek out and catalogue long forgotten drinking troughs on the North York Moors.

Gurli continued “I do not know much about troughs (we had one at home when I was a child), but since I read your father’s book I notice every trough I see. On some occasions I just take a look at it or into it, and at other times I take photos. But from now on I am sure I will look at the pattern if I see one.”

My column also prompted John Buckworth to contact me on a related subject: “Your article on the stone trough reminded me of the huge millstone in the middle of the moor west of Kildale…I’ve visited it a few times but it is not on a public footpath and difficult to locate when the bracken is up. It is about seven feet in diameter and the top face is finished and ready to flip over and face off the other side. It would take a good team of horses to move it. The nearest water source would be Kildale I assume. I have known about it for 50+ years…I would love to know more about it.” John, like me, imagined that it would have taken the mason many hours of hacking the stone out, and yet the other side remains unfinished. Why, after all that hard work, did he not complete the job?

I wonder if there are any readers out there who know the stone and the history of the area who has any suggestions as to why that is the case? (Please note: I have deliberately not published the exact location due to the fact it is not on a public footpath and there are nesting game birds that should not be disturbed).

Last time I wrote about troughs, I also bet that my dad had a file on them. Sure enough, on my last trip home I found it. But I’ve now run out of space, so I will have to leave what I have discovered for another day.
