Field plowed and harrowed with an 

 ordinary peg-tooth harrow. The stalks

 the clods and air spaces that stop the 

 upward trend of moisture 



Field showing disked stubble plowed, 

 disked and harrowed. Can you imagine 

 a better seed bed for the planting of 

 corn or any grain 



Illustration showing the field above 

 planted with corn and small grain. The 

 farmer is never certain of his crop.

 tion, and are of no service as fertilizer 

 when left in this condition

 in the illustration above, with corn 

 and small grain planted. The ground 

 is in perfect condition for the reception 

 of the seed, and the farmer has good 

 assurance that he will grow a crop
