REPORT OF THE COMMISSIONER OF AGRICULTURE. 



During the first week of onr work there were 987,945 pounds of cane 

 cut. This cane contained 90 per cent, of juice, of which 83 were seiit to 

 the clariliers; therefore obtained (calculating- by the analysis above 

 given) : 



Per cent. 



Crystallizable sugar 8.81 



Glucose 1. 25 



Foreign substances 0. 46 



The loss of juice by clarification, skimmings, and sediments in sirup 

 tanks amounts to about per cent, on the weight of the juice, or 4.98 

 per cent, on the weight of the cane ; therefore, amount of juice really 

 obtained in green sugar, 78 per cent, on the weight of the cane. Of this 

 8.1*8 per cent, crystallizable sugar, 1.17 per cent, glucose, 0.43 per cent, 

 foreign substances. 



According to the established analysis, every pound of foreign sub- 

 stances in cane juice prevents the same amount of sugar from crys- 

 tallizing; and furthermore, through the influence of great heat, long 

 continued in open kettles, a further amount of crystallizable sugar is 

 converted into uncrystallizable sugar. To be on the safe side, double 

 the amount of glucose would represent the disturbing element in crys- 

 tallization of the sugar contained in the diffusion juice, the perturbing 

 action of the heat included. Under these circumstances we ought to have 

 had, in dry substances, 6.68 per cent, of crystallizable sugar, 3.20 per 

 cent, of molasses. 



To compare the above with the results obtained in our run, it will be 

 necessary to reduce the amount of dry substances to the same basis. 



Per cent. 



The amount of water in the sugar is 1.50 



The amount of glucose and foreign substance 0. 7c 



The amount of water in the molasses 20. 0C 



This would give us 6.S3 per cent, sugar, 3.78 per cent, molasses. Total, 

 10.01 per cent., against 10.37 per cent, actually obtained, showing a loss 

 of 0.24 per cent., which has to be charged to profit and loss, attributable 

 to want of control in the sugar- house.
