ments has worked to the detriment of the trade in flagstone and 

 curbstone. As a partial counterbalance to these losses, a tremendous 

 development has occurred in the crushed stone business through 

 the requirements of concrete construction and road building; yet 

 altogether the changes in progress mean a positive loss industrially, 

 since they involve the substitution of cheap mechanical operations 

 for the trained skill of manual labor.

If the output of stone is distributed according to use it will be 

 found that more than 50 per cent of the product in value is repre- 

 sented by crushed stone. Limestone and trap are the principal 

 varieties employed for crushing. About 10 per cent of the value 

 consists of building stone, with sandstone, marble and granite as 

 the principal kinds. Curbstone and flagstone account for somewhat 

 less than 10 per cent of the value, and are restricted practically to 

 sandstone which lends itself most readily to such employment. 

 Among other applications that call for appreciable quantities may 

 be mentioned lime and furnace flux, for which limestone is the main 

 representative; paving blocks (sandstone and granite); monumental 

 s tone (marble and granite) ; and rubble and riprap (various) .
