 bine enough water with the lime to change 

 it to hydrate form, and that adds 18 pounds 

 weight. It is run through a sieve to remove 

 any coarse material, and then packed in 

 bags which help to exclude the air. The 

 small packages in which it comes upon the 

 market make handling easy, and this helps 

 to bring it into demand. Its good physical 

 condition makes even distribution possible, 

 and thus permits maximum effectiveness to 

 be obtained. It is only slaked lime, identi- 

 cal in composition and value with lime of 

 the same purity slaked on the farm, but 

 some dealers have been able to create the 

 impression that it has some added quality 

 and peculiar power. This does no credit to 

 the public intelligence, but the hunger of 

 soils for lime is so great that investment at
