RIGHT USE OF LIME IN SOIL IMPROVEMENT 



such that a relatively heavy application can 

 be safely made. The distribution is neces- 

 sarily uneven, and if the required amount 

 goes upon all the surface, a great excess is 

 sure to go upon a portion of it. Very often 

 an excess of water puddles much of the lime 

 in the pile, and lumps may be seen lying in 

 ineffective form in the soil for years. The 

 practice is responsible for much of the ex- 

 cessive application that brought the use of 

 caustic lime into disrepute. 



Slaking In Large Heaps. A preferable 

 method is to put the lime in flat heaps of 

 large size and about four feet deep, so that 

 water may be applied or advantage be taken 

 of rainfall. The value of the lime is so 

 great that one can well afford to draw water 

 and apply with a hose so that the quantity 

 can be controlled with exactness. When 

 fresh burned lime is perfectly slaked, each 

 56 pounds of pure lime becomes 74 pounds 

 of hydrated lime, water furnishing the 

 added weight. 



Hydrated Lime on tKe Market. A pop- 

 ular form of lime on the market is the 

 hydrate. Manufacturers first burn the 

 stone, and in the case of a pure limestone 

 they drive off 44 pounds of each 100 pounds
