In addition to above there was $93,000 of manufactured stone 

 sold for building and other purposes. 



As these figures represent nine-tenths of all the blue-stone, which 

 is quarried in the State, the total output may be safely stated to be 

 6,400,000 feet, and its value, in round numbers, $1,750,000. 



Slate. 

 The output of red-slate, in roofing, for 1887, is reported by W. A. 

 Nixon of Middle Granville, to amount to 5,000 squares.
