METHODS OF PLOWING 141 



furrow is too wide in proportion to its depth; to 

 correct this, the clevis must be moved to the left. 

 If the furrow stands too nearly on edge it is narrow 

 in proportion to its depth; move the clevis to the 

 right. A plow that is properly adjusted should 

 run in the soil for some distance without being 

 held, cutting a furrow of even depth and width, 

 provided the soil is free from stones and other 

 obstructions. If it will not do this either the plow 

 is a poor one, or, what is more likely, it is not cor- 

 rectly set up or adjusted. When it runs all right, 

 lower the beam wheel until it just touches the sur- 

 face. Thus adjusted the plow will do its best 

 work as easily as it can be made to run.
