FAKM IMTU'IMKNTS. 127 



Crossbill's Clod-crusher is a much heavier implement 

 than either of the preceding, but is the same in principle 

 except that the discs or sections are serrated and are 

 of two sizes, one being bored much wider than the axle 

 while each alternate one is bored to tit it exactly. This

arrangement permits the loose discs to eject any clods 

 that may get jammed between the closer fitting discs. 

 The Crosskill is principally used to pulverize hard clods 

 but it is more desirable to plough the land when it is 

 iu a friable condition, thereby rendering it unnecessary 

 to use such an heavy implement. Cost, fifteen to twenty 

 pounds.
