SIR : I have the honor to submit herewith for your inspection and 

 approval the results of the experimental work carried on by your direc- 

 tion in Louisiana during the manufacturing season of 188G by Mr. G. 

 L. Spencer, assistant in the Division of Chemistry. 



The information collected is of the highest interest to Louisiana sugar 

 growers, and is made still more valuable by some comparative studies 

 of the Cuban sugar industry. 

 Very respectfully,

SIR: 1 have the honor to submit the third report of the Department's

Included in this report is a brief statement of the work of three Cuban 

 sugar-houses, indicating certain economies that it would be well for the 

 planters of this country to adopt.

 my reqiiCvSt by Dr. C. A. Crarnpton. This contains a valuable tabli-, 

 devised by Dr. Crarnptoii some years since, and which is now employed 

 at the Department's stations for the calculation of analyses.
