This photograph shows Mr George Ellis, a retired quarryman, demonstrating the 'car gwyllt' - a seat on wheels - which was used by the quarrymen to descend the three inclines down from Graig Ddu quarry at the end of the working day. The 'car gwyllt' was usually made by the quarrysmith for some 5 shillings and was light enough to be carried on the shoulder between each incline. At the end of the journey near Bethania chapel, the 'car gwyllt' was put in a wagon and winched up to the top of the quarry, ready for the next working day.
