Description: Silver Grey Quarry, Creetown. Kirkcudbrightshire. A large granite block being prepared for splitting on the quarry floor by means of 'plug and feathers' method. Two quarrymen can be seen inserting the 'plug and feathers' into a large granite block. A recently separated block can be seen in the foreground. A series of narrow holes a few inches apart were drilled by a pneumatic drill. Two half cylinders of steel called 'feathers' were inserted into all the holes. A steel wedge-shaped 'plug' was then inserted. The plugs were then hit in succession with a hammer and a straight split in the granite block would result.
