saw is operated much in the same manner as a circular saw for 

 sawing wood. The planer consists of a heavy steel blade about 

 8 inches wide mounted so as to remain stationary while the 

 slab of slate passes under it on a sliding- table. By setting the 

 blade at the proper distance the slab can be trimmed and 

 smoothed down to a level surface. 



The most striking feature that is presented to a visitor in the 

 slate region is perhaps the enormous piles of waste material. 

 The waste in slate quarrying exceeds that from the quarrying 

 of any other material, the dump often claiming 60 per cent of 

 the total slate quarried. Some of the waste slate is ground and 

 utilized in making paints and pigments while attempts at its 

 utilization in cement and brick making have been made.
