perfect as possible; and how indispensable it is for the suc- 

 cessful growth of crops, that the implements used to effect 

 this purpose should be most perfectly adapted for it. 



Harrowing will be the most effective and useful the soon- 

 er it follows the plowing. As soon as the soil% turned it 

 begins to dry very quickly; and if at all adhesive, it forms 

 intractable clods which resist all efforts to pulverize them. 

 But when the harrow follows the plow, the moist soil is eas- 

 ily and quickly reduced to a fine tilth, and when well pul- 

 verized it does not dry out as when left untouched for a few 

 days after the plowing. This is very important when pre- 

 paring the soil for fall crops, because the plowing should be 

 done as early as possible and before the dry weather bakes 

 and hardens, it. Then an immediate harrowing breaks it 

 up and mellows it, and repeated harrowings consolidate it 

 and fit it in the best manner for the seed.
