find the wagon box as suitable, and many people 
prefer it. 
In mixing, spread the materials over the floor 
to the depth of five to ten inches, putting the bulk- 
iest fertilizer first; on top of this, spread layers of 
the remaining materials; and then mix thoroughly, 
shoveling over several times. When a great many 
tons are to be mixed this operation will need to be 
repeated often and the material bagged as mixed. 
In case you find any unmixed material has become 
hard and lumpy in the sacks, first put it in a sepa- 
rate pile and break up finely with a maul or shovel. 
This done, it is ready for the mixing pile to be 
handled as described above. 
WHAT KINDS TO USE 
You will, of course, decide what materials you 
wish to use, and in doing this you should be gov- 
erned by the commercial value rather than by the 
name. The State Experiment Station will assist 
you in suggesting a formula to use and the materi- 
als to buy. 
Here are a few general suggestions it is well to 
bear in mind in doing the work: 
1. Nitrate of soda is immediately available when 
mixed with the soil. Therefore it should furnish 
no more than one-third or one-half of the nitrog- 
enous part of the fertilizer. 
2. Sulphate of ammonia is open to the same 
objection as nitrate of soda, but to a smaller de- 
gree. 
3. Cottonseed meal decays slowly, and at the 
price for which it can be bought at present, may 
be used with economy as a nitrogen carrier.
