occur, and to what degree they affect the final results in 

 many instances. The following statement is presented as a 

 fair one, and may serve the purpose just specified : — 



One hundred parts of sugar-beet roots, under fair manage- 

 ment, are liable to lose sugar as follows : — 



Per cent. 



In the pits by degeneration 2.00 



By change into grape-sugar 0.54 



In process of filtration of the juice . . . .0.14 

 In defecation and carbonization .... 0.21 

 In juice left in the press-cake . . . . . 0.76 



Total loss 3.65 



One hundred parts of sugar existing in the beet-roots 

 were, in one case, accounted for in the following way at the 

 close of manufacture : — 



Per cent. 



Crystallized sugar 62.46 



Sugar left in the molasses 14.75 



Lost during manufacture 22.79 



Left in the pi'ess-cakes 11.48

Eight per cent of sugar from the beet is at present assumed 

 to be the actual result of most factories with improved modes 

 of operation and superior sets of apparatus : some factories 

 claim even more. The importance of an increase in the yield 

 of crystallized sugar may perhaps be best inferred from a 

 case reported by W. Crookes, F.R.S., in his late publication 

 on beet-sugar manufacture with reference to England. Mr. 

 Baruchson, the beet-sugar manufacturer, is reported as stat- 

 ing that the factory cost £10,845 ; 150,000 pounds of sugar- 

 beet root has been worked per day for five months ; the ex- 

 penses for labor amounted per year to £5,190 ; the total 

 expenses per year had been £13,980; the total receipts per 

 year were £20,470 ; the profits thus had amounted to £6,490, 

 or twenty-four and three-fourths per cent on the first outlay ; 

 six and a half per cent of crystallized sugar had been the re- 

 sult. He further states that one-half per cent of increase of 

 the yield of crystallized sugar would be equal to seven and 

 a half per cent additional profits. Eight per cent of crystal- 

 lized sugar from every hundred pounds of beet-roots worked 

 would thus insure a profit of forty-eight per cent.
