surface soil. Burned lime should be worked into the sur- 

 face soil as soon as practicable after application and before 

 it has had time to change to the carbonate form. A uni- 

 form distribution is not difficult when machinery is used. 

 Lime distributers are very efficient and make a profitable 

 investment. If no machinery is available and the lime is 

 spread by shovel from the back of a wagon, the soil should 

 be worked very thoroughly immediately after application. 



Analysis and guarantee. 



Nearly all states now require guarantees showing chemi- 

 cal and mechanical analyses of all forms of lime, and the 

 farmer should be careful in the purchase of lime to require 

 such an analysis and guarantee. Such an analysis should 

 show the form of lime, the percentage of actual lime, the 

 percentage of magnesia, the impurities and the fineness 

 of division in the case of carbonate of lime.
