REPORT OF THE CHEMIST. 



tained, 440 hogsheads, nt 1,150 pounds each. Total amount of sugar, 

 500,500 pounds; 1,000 barrels of molasses, at 43 gallons, 12 pounds per 

 gallon, equal to 510,000 pounds. Sugar and molasses, total, 1,0^2,500 

 pounds. 



The production of saccharine matter was G.40 per cent, of the cane 

 worked. Now, if the result obtained had been the same as that by dif- 

 fusion, 10.07 per cent, (from very inferior and deteriorated cane, the 

 juice of which weighed only 0.06 Beaume), the result would have been, 

 sugar and molasses, total, 1,703,079 pounds, which is a surplus gained 

 of 080,579 pounds. To sum up, if the cane on Messrs. McCall's planta- 

 tion had been worked by diffusion, and would have had only the same 

 weight of Beaume, 0.00, and had deteriorated besides, the result ob- 

 tained would have been 203 hogsheads of sugar and 005 barrels of mo- 

 lasses, more than was obtained under the old process. 



Col. Amedee Bringier stated that he had chosen the finest cane on 

 his place in order to test as exactly as possible how much could be ob- 

 tained by one of the best mills in the State, and one of the most econom- 

 ically-conducted sugar-houses. Fifty one acres, at 57,704 pounds per 

 acre, are 2,047,500 pounds; the cane juice weighed 8° Beaume\ 



Production of sugar pounds.. 135,272 



Production of molasses do 74,97G 



Total green sugar 210, 248 



Or 7.13 per cent, of saccharine matter to cane worked. 



The great preponderance of sugar over molasses in this result is due, 

 first, to the good condition of the cane; secondly, and principally, to 

 superior handling and working of the cane juice after leaving the 

 rollers. 



Assuming he had obtained the result gained by the diffusion process, 

 he would have had 314,498 pounds of sugar and molasses, which is a 

 surplus over this result of 104,250 pounds; or, calculated in the same 

 proportion as his relative quantities of sugar and molasses — total sur- 

 plus sugar, 07,304 pounds; also surplus molasses, 3G,8G0 pounds. 



As a matter of special interest, the report of Mr. Ludwig Kolhnan, . 

 techuical director of these experiments, is here given: 



On this place the weight of the cane was carefully registered during 

 our work : the quality of the cane was tested from time to time by pass- 

 ing a few canes through a small set of hand-rollers and the juice weighed 

 with a very delicate saccharometer. During this our first week's run, 

 the analyses of the mill juice and diffusion were as per table following: 



To avoid all misapprehension it must not be forgotten that for every 

 100 gallons of mill juice we had 113 gallons of diffusion juice, which ac- 

 counts for the apparent higher rating by saccharometer in mill than in 

 diffusion juice.
