passes through all of the mills in order that as much of the juice as possible may be extracted. The cane after it is crushed is termed "bagasse" and is conveyed by a carrier directly to the boiler furnaces where it is consumed as fuel. In many of the factories the cane leaving the second mill and sometimes that from the first mill is sprayed with hot water. This process of spraying water on the crushed cane is known as "maceration" and facilitates the extraction of the sucrose or sugar content in the cane. The component parts of sugar cane are juice and fibre, the juice being known as the water or moisture of the cane with all its solids in solution. The juice is made up of sucrose, moisture and impurities, and these impurities, such as organic acids, nitrogenous bodies, etc., are partially removed from the raw extracted juice by the defecation or clarification process and in part accumulated in the final molasses. The mixed juice coming from all the mills is first strained through wire screens or by Link-Belt strainers to remove particles of floating cane. It is then pumped to the top of the factory building and enters the liming tanks. Here milk of lime, about 15° Beaume, is added to neutralize the acids and is thoroughly mixed with the juice by means of compressed air. The limed juice is pumped into juice heaters where exhaust steam is used to raise the temperature of the juice to 215° to 220° F., and from these heaters the juice is discharged into settling tanks. The combined effect of the lime and the heat results in the formation of many mineral compounds which settle to the bottom of the tank, carrying down, also, some organic impurities which
