THE OLWER PLOW BOOK 



f the plow bottom shown in illustration G. Observe that the 

 ground is very finely pulverized and the few clods are flat. The surface 

 of the ground is level; furrow crowning is imperceptible. The furrow

have clay in their composition. This bottom thoroughly 

 pulverizes clay if the soil is in a condition to be plowed. 

 The shape of this mouldboard is such as to cause the 

 earth to separate in layers rather than to break into 

 lumps. It is distinctly noticeable in a field plowed with 

 this bottom that the few clods left are always flat shaped 

 and very frequently will fall into pieces when picked up. 

 Naturally, a bottom that does this kind of work requires 

 more power than one which does not pulverize the 

 ground as effectively.
