Does anyone know of any printed references which give details of the
hydraulic pumping engines and Water Balances at the Penrhyn Quarries at
Bethesda ? I seem to remember one I read years ago, but can't remember
where. Or does anyone have any photographs of the "inner" side of the water
balance cage which used to be in the headgear just outside the quarry
office ? It seems to have been removed in recent years, and when I saw it
in the early 1970's I neglected to take other than the "standard" 3/4 on
view of the whole headgear which shows the "outer" side. Finally does
anyone know what the arrangements at the foot of the shafts were ?
Any help would be appreciated.
