safe to use in fairly large amounts on the land. 
Probably no harm would result from using as much 
as six tons to the acre of air slaked lime. One may 
burn his own lime and, putting it in piles, let it air 
slake on his own farm if he has time to wait, or he 
may buy it cheap from the refuse about the kilns. 
Bear in mind that it has gained in weight in slaking, 
and is only about two-thirds as strong as the fresh 
burned lime. a 
Ground lime is fresh-burned lime ground ready 
for use. It is very convenient to distribute, and 
there may possibly be some virtue in having it slake 
in direct connection with the land. The only objec- 
tion to its use is that manufacturers often charge 
pretty well for grinding it. The farmer can some- 
times grind it at home, or he can buy lump lime and 
slake it at home at almost no cost. He can pile the 
lime in little piles of a bushel in a place over the 
field ‘and let it slake by absorbing moisture from the 
soil; then when it is in powder spread it at once with 
the shovel. Or he can slake it to powder in a large 
pile and apply it with a lime distributor or by use 
of the manure spreader. To first lay down in the 
manure spreader a thin layer of chaff or manure 
and set the machine on the slow speed, will make it 
work very well. Many manure spreaders are now 
made with special lime distributors. 
Time to Apply—When is the right time to put on 
caustic lime? Not in direct connection with manure, 
since it will doubtless attack the manure and set 
free more or less nitrogen that may possibly be
