PREFATORY NOTE. 



SIR : In submitting to you the results of Mr. Hubert Edson's work at 

 Calumet Plantation, La., during 1888, I desire to call your particular 

 attention to the fact that the yield of sugar by the milling process 

 reached the unprecedented amount of over 200 pounds per ton. This 

 remarkable yield was the result of a rich crop and careful chemical and 

 technical control of the factory. 



It is believed that the data of this work here published will prove of 

 great benefit to the sugar planters of the country. 

 Eespectfully, 



H. W. WILEY, 



Chemist. 

 Hon. J. M. KUSK, 



Secretary.
