The face-stones and through-stones will be packed with rubble: smaller stuff to fill the middle of the wall and the awkward chinks and gaps in the faces. A day's work will be a 'lift' or 'course' of 400-450 mm vertical which is finished to a horizontal level from which to start the next day's work. They were quite fussy about these horizontals: we have slates and fire-brick shards embedded in the wall to bring up a bit of a dip. It was never intended that the structure of the wall would be revealed to human gaze - we spent a lot of time chipping off the plaster, which gave the rooms a smoothe public face, to reveal the bricolage of structural function.
A mason once told me that the trick was to never return a rock to the pile - find a place for it somewhere. in the work. And in ainm Dé, wear steel-capped boots! Rubble-in-courses won't do for the [door and window] openings. These are often finished in bricks which cost ready money, but have uniform dimensions and make a definitely straight vertical edge which makes the carpenter's work easier. The lintels are typically made of roughly squared granite slabs which have been split from the living rock with hammer and wedges.
You can see the wedge marks both on the lintels and on the lump of rock which got left behind on the hill. I've clipped a detail [L] to show the wedge-marks highlighted in the oblique light of the setting sun. It also shows that the lintels typically come as a pair so that they can bridge the half-metre thick granite walls. The pair shown left are 2700mm = 9ft long and they have both been i) split from a suitable boulder on the hill ii) brought down to the yard on a sled iii) lifted unto the wall-top. All without the help of petrol or steel-capped boots. We live in The House the Bomb Fell On in 1941. Actually we don't, that would have been wet and draughty with half the roof blown away. We live in the house constructed from the rubble in the Summer of 1941. We know the stone-mason's name because someone told us when we arrived. But also because he humbly left his mark on two smears of sand-and-cement on the gable-end of one of the sheds which was also reconstructed at the time [see pics at top]. We have no idea who his mate was; it may well have been a rotating meitheal of local men who'd be happy to help re-house their neighbours if it was too soggy to make hay.brown touristic interest sign the size of a bed-sheet that the county council installed at the bottom of the lane a couple of years ago. I could have been over my dead body about it; but I firmly believe that we don't own the house, let alone the Ringstone, we are holding it for future generations. "We have not inherited the land from our fathers, but have borrowed it from our children.” Probably not Chief Seattle: more likely Wendell Berry. [prev]. Nevertheless, the sign is on Friendface, GooglerMaps which means a trickle of randomers appearing in our yard for their Sunday afternoon entertainment. I usually make time to chat, especially if the visitors have asked about parking rather than, like, parking.
