a board floor and given only suflBcient moisture to insure 

 active fermentation without leaching. In other words, the 

 composts were kept under the most favorable conditions for 

 about one month, or until April 16, when composts, fresh ma- 

 nures and commercial fertilizers were placed in the drill. Low 

 beds were then thrown up above the fertilizers. Peerless cot- 

 ton was planted April 19 in a seed bed, that was too loose on 

 all plots. 



The following table shows the character of fertilization 

 and the yields of seed cotton :

The figures in the above table show plainly that there was 

 no advantage in composting acid phosphate, stable manure, 

 and cottonseed meal, but that on the other hand the plots re- 

 ceiving this compost yielded 54 pounds of seed cotton per acre 

 less than the plots to which the same fertilizing materials were
