The land was not uniform in natural productiveness, but 



improved in quality from the first to the last plot. While 

 the results are not perfectly uniform, the pulverized raw 

 phosphate evidently produced as good, if not better, results 

 than the acid phosphate whether used alone, or mixed with 

 cotton seed and cotton seed meal. 



EXPERIMENTS IN THE CHEMICAL LABORATORY. 



Anticipating these results experiments were carried on in 

 the laboratory during the summer to determine whether they 

 are due to the fact that decomposing organic matter converts
