Stone Dusting minimises the danger. Stone Dust is easily and cheaply made if you have one of Alien’s Special Stone Dust Making Plants. They are simple, strong and self-contained. They have many advantages over other types of machines. If you do not yet know about them, write at once for details ! Edgar Allen & Co. Limited, Imperial Steel Works, SHEFFIELD. D.
