This process of splitting stone with wedges is said* to have been first 

 brought into general use in this country by a poor mechanic named

 quairymen of that place. So much did the adoption of this simjile 

 method facilitate granite working that the price of the cut material 

 dropped within the space of a few months over GO per cent. Prior to 

 this time the stone after being blasted from the quarry in irregular 

 blocks was squared down to the proper size by cutting a groove along 

 a straight line with a sliarp-edged tool called an axhammer, and then

 groove until the rock was broken asunder.t
