Two workmen working on the channelling machine for Slate at Oakeley Slate Quarry.
The work of a channelling machine. A series of holes are bored close together through the thickness of the block it is desired to remove. When the partitions between the holes are removed by a cutting tool there is a deep channel seperating a lower block from the slate that is still in position.
