 common laborer. Now all these things are done by machinery. 

 The coal breaker and coal screen moved by steam have taken 

 the work from those who formerly had nothing else to depend on. 

 But, on the other hand, they are important elements in a trade 

 that has so increased as to employ thousands in the place of the 

 former tens. So, also, of the match machines, in consideration

 we suppose, that even a huge wood-splitting machine will benefit 

 the class that it now competes with injuriously.

 that secure the bur-arbors, in place of being fixed to the frame, 

 are made to move on pivots; so that while the burs rise and fall, 

 the journals remain centered in the boxes, while screw washers 

 adjust the proper and shake. 3d, The bui-sare hollow cylinders, 

 placed in the arbors, and hence can be removed for sharpening, 

 and others substituted without removing the arbors.
