REPORT OF THE COMMISSIONER OF AGRICULTURE. 



before and after clarification. The rest of tlie samples were taken at 

 intervals from tlie presses and from every third clarifier of juice. 



The average of these results will represent, as nearly as possible, 

 the same juice before and after treatment. 



Table XI. — Shoiving analyses of juices before and after treatment by Kleemann 



proce^. 



Average increase in coefficient of purity — 3.14. 



In the preceding table, column A represents raw juices; column B, 

 juices treated by Kleemann's process. Referring to table, we find the 

 average increase in the coeflScient of purity by the ordinary process to 

 be 1. 24. Table XI shows an increase of 2. 14 by the Kleemann process. 

 This large increase in the purity of the juice would give a decided 

 increase in the yield of sugars. 



THE ALBUMINOIDS. 



The reduction in the percentage of albuminoids was not as large as 

 by the ordinary process. By the Kleemann process an average of 

 35.17 percent, of the albuminoids were removed; by the ordinary 

 process the reduction was nearly 45 per cent. I do not know to what 

 extent this difference in the albuminoids would affect the working of 

 the sirup. The sugar-maker reported that the sirup made by the 

 Kleemann process in this test worked as easily as by the ordinary. 



. ADVANTAGES OF THE KLEEMANN OVER THE ORDINARY PROCESS. 



The increased coefficient of purity is not the only advantage this 

 process has over the ordinary. There is an increase of sugar from 

 the rapidity of working both juice and sirup. The quantity of 

 sugar lost in the scums is reduced to a minimum. The expense for 

 labor is less and the value of the press cake is greater, since it is in a 

 better condition mechanically for use as a fertilizer. 



This process certainly merits a thorough test by our sugar planters. 

 Lignite of a good quality is abundant near the sugar area of Louisiana 

 and can be obtained at a small cost.
