phate is placed, next a layer of cottou seed, this alternation 

 being oontinued until the materials are exhausted. 



The cotton seed employed in the compost should be 

 moistened thoroughly, and the heap after its completion, 

 should be saturated with water containing 100 pounds of 

 Kainitein solution. The heap shouli be covered with a layer 

 of rich earth or vegetable mould, or better still with a thin 

 layer of gypsum; any liquid drainings from the stable 

 which may be at hand, can be used to advantage in moisten- 

 ing the heap from time to time. The bed should be pro- 

 tected from rains by a shelter, and the heap should be left 

 undisturbed for a period of from three to six weeks. When 

 ready for use, the heap is broken up and the materials are 

 thoroughly mixed and incorporated with each other. The 

 quantities of this compost applied to the soil should be just 

 about double the quantities of the average complete fer- 

 tilizer ordinarily used on the soil or crop in question, 

 i, e. — from 300 to 600 pounds of the compost per acre. 



The composition of such a compost would be approxi- 

 mately as follows : 





500 ft) Acid Phosphate . 



700 " Cottonseed 



800 " Stable Manure. .

The percentage composition would be :

Potash .64%. 



The addition of the kainite will increase the potash per- 

 centage to about 1.2, and the fertilizing value of the complete 

 mixture, calculated on a fertilizer basis, will be about $9.70,
