travelling conveyor, by whicli it is delivered down a chute to the 

 Mills. 



The Mills consist of a crusher for preparing the cane, and 

 three Mills, each having three rollers weighing some nine tons 

 each, and all driven by one 400-horse-power Engine, followed by 

 a powerful fourth Mill of three 12-ton rollers, driven by one 250- 

 horse-power Engine. The Cane passes in a continual blanket or 

 mat through the successive Mills, and refuse crushed cane — 

 known as bagasse — issuing from the fourth Mill is conveyed to 

 the Boilers and burnt for raising steam. 



The Boilers consist of four Babcock and Wilcox Water-tube 

 boilers and one Westgarth " Nesdrum " Vertical Tube Boiler. 

 There is one chimney of steel plates 150 feet high. 



The Juice extracted by the Mills is passed through strainers, 

 heated and clarified in a large battery of settling tanks, from which 

 the clear juice passes to a triple effect evai)orator, where two- 

 thirds of the water is evaporated off. The resulting liquor, now 

 known as syrup, is then pumped to storage tanks, from which it 

 is drawn into the Vacuum Pans, in which it is boiled to Masse- 

 cuite, that is until the grains of Stigar are formed to the required 

 size, surrounded by molasses as the " Mother Liquor." 



The Vacuum Pans are discharged periodically, when and as 

 the process is completed, the issuing Massecuitc is allowed to cool 

 s-lowly, and then conveyed to the Centrifugal machines, which 

 consist of perforated baskets about 36 in. diameter, lined with 

 fine wire gauze. These I)askets revolve at a high velocity ; the 

 centrifugal force expels the molasses through the gauze and the 

 dry marketable Sugar is left behind in the basket. The Sugar is 

 discharged on to a Conveyor, by which it is carried to a " Jacob's 

 Ladder " elevator and deposited on an overhead floor. From 

 there it is thrown down chutes into bags, weighed and sewn up 

 ready for shipment. 



( )riginally built to crush 500 tons of cane in 24 hours, this 

 Factory has ])een added to year by year until now it is ca])able of 

 crushing 900 tons in 24 hours, equivalent to a weekly output of 

 some 450 tons of dry Sugar. 



Any quality of Sugar can be made here, from Brown Sugar 

 for the Refineries to \\niite (iranulated Sugar for direct consump- 

 tion, without passing over Charcoal Filters.
