RIGHT USE OF LIME IN SOIL IMPROVEMENT 



exists for the product of all large plants, 

 while the number of small pulverizers mul- 

 tiplies rapidly. The very large areas that 

 have no limestone at hand must continue to 

 buy from manufacturers equipped to sup- 

 ply them, and farmers within a zone of 

 small freight charges should be able to buy 

 from such manufacturers more cheaply 

 than they could pulverize stone on their 

 own farms. 



An individual, or a group of farmers, 

 will buy a machine for pulverizing lime- 

 stone at a cost of a few hundred dollars 

 when costly equipment would be out of the 

 question. If he has a bed of limestone of 

 fair quality, and the soil of the region is 

 lacking in lime, an efficient grinder or pul- 

 verizer solves the problem and makes pros- 

 perity possible to the region. Within the 

 last few years much headway has been made 

 in perfecting such machines, and their man- 

 ufacturers have them on the market. Any 

 type should be bought only after a test that 

 shows capacity per hour and degree of fine- 

 ness of the product. As a high degree of 

 fineness is at the expense of power or time, 

 and as the transportation charge on the 

 product to the farm is small, there is no re-
