When extra care was taken in washing the cakes, as in the case of 

 the Louisiana experiments, to be later described, only a trace of sugar 

 was left in them. 



A glance at the composition of the cake will show its value as a fer- 

 tilizer. 



The quantity of liine used was nearly 1J per cent, of the weight of 

 the cane entering the battery. 



RESULTS OF WORK. 



The average weight of chips in the cells was 1,900 pounds. 



From the beginning of the first attempts to run the machinery (Sep- 

 tember 13) until it was found possible to save the product (September 

 29) 499 diffusions were made, amounting to 948,100 pounds. After be- 

 ginning to save the product (September 29) until suspension of work 

 (October 26) 1,945 diffusions were made, amounting to 3,695,500 pounds. 

 The total weight of cane, seed, and blades received from the field after 

 September 19 was 3,120 tons. 



The weight of chips diffused was 2,322 tons. The weight of seed, 

 tops, blades, and cleanings (by difference) was 798 tons. 



Following is the number of cells of chips used each day after Sep- 

 tember 19. Before that date no separate daily account was kept: 



About one-third of the cane received was partly stripped of its blades. 

 1 1 appears from the above figures that the seed tops, blades, and sheaths 

 of the cane will amount to nearly 30 per cent, of the entire weight. It 

 must also be remembered that much of the blades, sheaths, &c., was not 

 ivmoved by the very imperfect cleaning apparatus employed, and this 

 weight is included in that of the " clean chips."
