NORTHERN SUGAR INDUSTRY. 



WEIGHT OF CANE. 



The canes unstripped were brought from the field after the seed heads y 

 with a part of the stalk averaging about 12 inches in length, had been 

 cut off. 



WEIGHT OF JUICE. 



The defecating tanks receiving the juice were two in number. In all. 

 sixty defecations were made in the large tank and five in the small one. 



The avei?age quantity of juice received in large tank was 548 gallons, 

 which multiplied by 60=32,880 gallons. The average quantity of juice 

 received in small tank was 301 gallons, which multiplied by 5 = 1,505 

 gallons. In addition to this must be reckoned juice used for fermenta- 

 tion and other experiments, which may be estimated at 1,000 gallons. 

 The total number of gallons of juice expressed, therefore, from the Early 

 Amber cane is 35,385. The average specific gravity of this mill juice 

 was 1.06, and the w^eight of one gallon 8.84 pounds. 



The total weight of juice expressed was 35,385 x 8.84=312,803 pounds. 



The percentage of juice to gross weight of cane was 41.9. The per- 

 centage of juice to net weight of cane was 312,803-^671,715=46.60. 



A POOR YIELD. 



The yield of juice was remarkably poor. This was due to two causes, 

 viz : (1) The cane was crooked, broken, and tangled, so that it was al- 

 most impossible to get an even feed j and (2) the mill, built on the 

 model of mills designed for tropical cane, was not suited to grinding 

 the weak and yielding stalks of sorghum. 



The mill was constantly choking, the canes, after passing the first 

 rolls, becoming tangled in the "knife" and forming into a wad that 

 would not pass the second rolls. 



In order to make the mill work it became necessary to loosen the third 

 roll somewhat, and this allowed the canes to pass without sufficient 

 pressure. 



WEIGHT OF BAGASSE. 



A few experiments were made to defcermine the percentage of juice 

 expressed by weighing the bagasse. 



On September 14, 6,700 pounds cane gave 2,730 pounds of bagasse 

 and 3,970 pounds of juice = 59.2 per cent. 



On September 27, after the rolls had been opened to allow more rapid 

 work, 3,420 pounds cane gave 1,660 pounds of juice=47.9 per cent. 



On October 1,2,160 pounds cane gave 970 pounds juice = 40.3 per cent. 



On October 3, 2,360 pounds cane gave 1,200 pounds juice=5().8 per cent. 



On October 5, 2,020 pounds cane gave 940 pounds juice=46.5 per 

 cent. 



Since all the juice exjiressed was measured, I did not think it neces- 

 sary to continue these weights. Those that are given, however, only 

 give additional emphasis to the results obtained by measuring the juice.
