Rule’s Shaft winding engine

Remains of a whim at South Caradon Mine

Rule's Shaft winding engine loadings

One of the most interesting, but least visually prominent of the South Caradon engine houses.

It housed a horizontal 22″ (or 24″) single cylinder engine, a type pioneered in Cornwall by William West.

The building has been demolished and stone robbed but its outline can still be identified.  A deep hollow to the east identifies the location of its boiler house. The chimney still stands behind the boiler house.

The prominent blocks of masonry are the granite loading for the winding gear. It does not however appear to line up with the shaft. The Brenton Symons map shows the engine as WE to the north of what is marked as “New Shaft”.

Brown and Acton state that the engine powered two drums fitted with clutches enabling both Rule’s and Holman’s shafts to be wound. The rubble to the right marks the site of the engine house

South Caradon Mine in 1843

A Victorian Mine through Victorian eyes

As a bit of a break from the string of posts covering the engine houses at South Caradon, I have dipped into the old website and pulled out one of the contemporary reports, given it a bit of a freshen up, and added some new photographs. Hope you enjoy the read.

“The prospects are exceedingly brilliant, and not surpassed by any other mine in Cornwall”

South Caradon Mine was on the up in 1843, a star of the British mining scene. This report from the mining commentator and share dealer J.Y Watson reflects its high status in the eyes of the industry.

A compendium of British Mining, Watson 1843

“In the parish of St Cleer near Liskeard was originally searched for tin, and when the lode was first discovered in Caradon Hill, and found to contain a quantity of gossan, it was considered so favourable to the existence of tin, that it was with difficulty a company was formed to work it; but the messrs. Clymo who has obtained the sett, persevered and three rich copper lodes were soon opened. The original outlay to the adventures before the mine made returns in August 1837 was only £327 8s 5d and from that time to the 31st March 1840 they sold copper ores to the amount of £15,635 10s 7d., paid all costs for machinery, including two steam engines and a whim; from that time to November, 1842 they have divided, altogether, a profit of £19,168 and are now receiving at the rate of £10,000 a year, with every prospect of greatly increasing the returns. Some mine agents have asserted that there is £150,000 worth of ore discovered in this mine; but be that as it may, the prospects are exceedingly brilliant, and not surpassed by any other mine in Cornwall. A great part of the workings are in Caradon Hill, which is 1,298 feet high. The monthly cost of working is about £18600”


This report was written at a time when the mine was growing,  but in a period when theMinerals in the South Caradon waste mines in the West of Cornwall had started to suffer. It had only been seven years since the Clymo’s had discovered the copper, and yet the figures being stated in this report are huge. It is no wonder the mine was being described in such superlatives as “exceedingly brilliant”.

The success of the mine was putting a strain on the local infrastructure. The roads proved incapable of providing the transport capacity required down to the port of Looe and a survey was commissioned in 1842 by a group of mine owners to build a railway from Caradon down to the Liskeard and Looe Canal. The route was surveyed by Robert Coad and the line was in operation by 1846.
This was a period of mass immigration of miners from the west of the Duchy. Over the next decade the population of many of the villages around was to double causing overcrowding and poor housing conditions. Drinking houses, brothels and makeshift miners camps allegedly grew up to serve the rapidly expanding workforce.

1843 was the year that the Clymo’s had started the lead mining boom in nearby Menheniot, with the launch of Wheal Trelawney.

Other events in 1843

To put the year in perspective.

  • Queen Victoria was on the throne
  • Robert Peel was Prime Minister
  • Marc Isambard Brunel’s Thames Tunnel, the first tunnel under the River Thames was opened
  • Isambard Kingdom Brunel’s SS Great Britain was launched
    Charles Dickens’s A Christmas Carol was published

Holman’s Shaft Pumping Engine

Navsbooks>South Caradon>Views> Holman’s Shaft

Back westwards across Caradon Hill in this post to return to the group of buildings around Rule’s and Holman’s Shafts.

Holman's Shaft from the west

The ‘Man in the Mine’ at South Caradon

This is the most imposing engine house on South Caradon Mine; dominating Caradon Hill’s southern slopes with its massive bulk and its well known  “Man in the Mine” shaped collapse in its western wall. A feature that has recently changed shape after stabilization work. It now resembles a ‘Lady in bobble hat’.

Being built in 1875 this engine house is not shown by Symons in his 1863 map of the Liskeard Mining District.

Holman's Shaft bob wall
Holman’s shaft is situated on the southern slope of Caradon Hill mid-way along the line of the southern lodes. It is located close by the less well preserved remains of Rule’s shaft. Around the shaft is a complex of buildings, tracks, tramways, tips and tunnels. With a prominent location on the southern slopes of Caradon hill the tips and engine house can be seen for many miles across South East Cornwall.

The shaft is sometimes called New Engine Shaft, with Sump Shaft being the original engine shaft.

Holman’s engine house has walls still standing to full height although some collapse has occurred around the openings. A result of the collapse on the southern side is a hole the shape of which resembles the outline of a hatted man who has run through the wall! The shaft on the eastern sideHolman's engine House in 2002 of the building is choked with rubbish and is subsiding. On the opposite side is the substantial remains of the boiler house which is sunk below ground level. No chimney exists as it was believed to share the stack with the nearby Rules shaft. Beside the engine house can be seen the remains of a tramway and a track tunnel passing under the spoil tips.

The 70″ engine it housed was built new for the mine by Harvey and Co in 1875. It was installed as a result of the adjacent Rule’s Shaft engine being unable to keep pace with the extra drainage required of the expanding workings underground.
On closure of South Caradon it was bought by West Wheal Grenville where it was restarted in in 1888.

The South Caradon remains plotted

Before looking at the last set of engine house at the South Caradon Mine I have had quick diversion into maps, a diversion that gave me the opportunity to play on the OS maps online website

South Caradon Mine panorama

The South Caradon explored with Grid References

‘Minions- An archaeological survey of the Caradon Mining District‘ by Adam Sharpe without doubt is the definitive resource on the industrial archaeology of Caradon Area. And now that the OS Maps on-line website has arrived there is a wonderful opportunity for armchair archaeology. Type in the grid references in the book into the webpage search, pinpoint the site and then switch on the aerial layer- a great way to read the book.  To reduce some of the typing for the South Caradon mine here is a list of hyperlinks to the locations. Enjoy exploring.

Copies of the book are hard to come by, so grab one when you see it.

South Caradon Mine’s most easterly shaft

The Caradon website resurrection has continues apace, this time looking at maps and views that cover the last three engine houses described.

Kitto’s shaft is South Caradon’s most easterly workings, lying close the boundary with East Caradon Mine. It is a collection of remains close to the car park at Tokenbury Corner that lie hidden behind extensive waste tips.

Although the engine houses are in a poor condition, none are standing more than a metre high, it is still a fascinating collection of remains. It is a historical set of remains as well, for this is the location of the last man engine installed in Cornwall.

In addition to the engine houses this map shows the tramway and leat layout. The tramways link the shaft with the tips, and also the dressing floor in the Seaton Valley. The leats  run westwards to supply the engine houses that lie across the slopes of Caradon Hill.

Kitto’s Shaft Winding engine

An elusive engine house site at South Caradon Mine

The site of Kitto's Shaft Winding engine

Only a short South Caradon Post this time, a short post because there is so little to see of this engine house.

This is last of the trio of engine houses at Kitto’s Shaft; and it is one easily missed when visiting the site. Kitto’s whim was located to the south of the more visible man engine remains. All that can be found there are are some grassed mounds and undulations. This engine has left even less remains than the piles of rubble that identify Jope’s Whim.

The whim was a 22″ beam engine which was sold when the man engine was installed at the shaft. Wheal Strawberry (St. Austell District) bought the engine in 1886.

The lack of remains is probably the result of its house being demolished to provide stone for the man engine house.

Kitto’s Shaft Pumping Engine

The most easterly of South Caradon Mine’s shafts

The diversion of these posts into Man Engine related topics has left it at the easterly end of the South Caradon Sett, and so this is where it will resume its journey through the engine houses of this famous Cornish mine.

Kitto's Shaft at South Caradon Mine
Kitto’s Shaft looking East. The pumping engine is on the left.

This engine house is often overlooked by the many walkers that use the track from Tokenbury corner; its low remains hidden behind the tips upslope from the track.

The Shaft

The shaft was sunk as part of the mine’s extension eastwards across the southern slopes of Caradon Hill. An extension that followed the rich trio of long loads, including the famous South Caradon Caunter lode. This expansion occurred in 1862-64 after an extended lease was agreed with Rev. Norris.

The shaft was unusual in having three shafts, accessing three lodes, in three directions from one collar. NW, NNW, SE. This can be seen in Dr.Russ’s amazing model of underground Cornwall found on his facebook page. Abandoned Mine Models> 

Kitto’s shaft is best identified at 2:23 into the video.

The Engine

Like several engines on this mine, author’s disagree on its size. The Minions report and Kenneth Brown State 35″, but Webb and Geach state 32″. Either way it was not a particularly large engine.

The engine was located to the north of the shaft with its boiler house lying to the east. Only lower part of engine house remains, although substantial balance pit exists. The Chimney now only stands about 1 metre high.

Two sources of information to look out for

Exploring Cornish Mine’s Volume 2 is a great resource for anyone wishing to explore South Caradon Mine. It is written by Kenneth Brown and Bob Acton, but unfortunately is now out of print. The footnotes are well worth a read, for this is where Kenneth Brown’s technical and historical information can be found.
