Sorghuvi Sugar in New South Wales. 



In a letter recently received from Mr. A. Fairgrieve, President of 

 the Colonial Sugar Refinery Company, Sydney, New South Wales, he 

 gives the following data of experiments in sugar production, from two 

 varieties of sorghum, which he calls the "Black" and the "Yellow.'" 

 He had not enough of the Yellow variety for experiments in sugar 

 making, but obtained a yield of 6 to 9 tons of stalks to the acre, and 

 of 1,200 to 1,800 pounds of seed to the acre. 



From 690 pounds of stalks, " cut just as the seeds were beginning 

 to harden," he obtained 38^ gallons of juice, the mill giving, at the 

 first pressure, 30 gallons, and the bagasse, being again passed through 

 the mill, yielded 8^ gallons additional. 



After defecation with lime, the juice had a density of 10° Beaume, 

 at 80° F., and only 31 gallons of defecated juice were worked for 

 syrup and sugar. 



From the 31 gallons of juice, 41 pounds of masse cuite were ob- 

 tained, which gave, of first sugars, 12| pounds, and, of second sugars, 

 5i pounds, leaving 23 pounds of molasses. 



"it Avill be seen that the mill gave only 48 per cent of the weight of 

 the stalks in juice, but the syrup yielded 44 per cent of sugar and 56 

 per cent of molasses. 



The products, then, from each ton of cane, was 

 52.2 pounds of sugar. 

 5.33 gallons of molasses. 

 5.36 bushels of seed. 



But, as the mill gave only 48 per cent of juice, while 60 should be 

 given by a suitable mill, and since only 80 per cent of the juice ex- 

 tracted was used in making syrup, the above results, with a good mill,
