and the day's work, that is, the 19,000 pounds of 

 boiled stuff (1600 gallons) gives 11, 400 pounds of dry 

 sugar of the first-strike, or sixty per cent of the boiled 

 stuff or again 5, 7 per cent of the weight of the 

 beets. 



The syrup which runs from the turbine and 

 which is called raw syrup, represents 40 per cent of 

 the boiled stuff, or 7,600 pounds. By proper treat- 

 ment this will produce another quantity of sugar. 

 For this purpose, the syrup which gauges 44 to 46 

 is placed in a boiler and it is brought to 30 B by the 

 addition of hot water, and it is clarified with bul- 

 lock's blood, arid powdered animal charcoal. 



CLARIFICATION. The syrup having been reduced 

 to 30 B, } per cent of bullock's blood is taken, say 3 

 quarts p T every 100 gallons, which is diluted with 

 3 or 4 times its volume in syrup and emptied into the 

 boiler. It is we'll mixed and 2 per cent of fine char- 

 coal is added. This is well shaken to mix it, and the 

 temperature is raised to 140. It is heated until 

 boiling point is reached. The albumen of the blood 

 in coagulating, rises to the surface drawing with it 

 all the impurities and leaves underneath a clarified 

 syrup which is filtered in the same manner as the 

 syrups at 27 and then boiled down. The syrup when 

 boiled down takes two or three weeks to crystallize 

 in vessels of a capacity of 4 or 600 gallons, placed 

 in what is called empli in which a temperature of 

 95 is maintained. 



The 7200 Dounds of boiled stuff which we obtain 

 will give, at 30 per cent, 2160 pounds of sugar of the
