EFFECT OF LEAVING CANE STRIPPED IN THE FIELD. 



One part of a patch of Minnesota Early Amber cane was 

 stripped of leaves and left standing in the field from September 

 15 to September 22. It was then cut, and the jaice, together with 

 some that had not been stripped, was analyzed, with the following 

 result : 



Cane stripped for one week,

The diminution of sugar is undoubtedly due to the fact that 

 the latent leaf buds found under each leaf begin to develop into 

 new leaves. These new leaves are formed partly at the expense 

 of the sugar in the cane. 



DEFECATION. 



The juice after it leaves the mill has a more or less green color, 

 due to the presence of large quantities of chlorophyl and other 

 vegetable substances, which must be removed. This process is 

 known as defecation. The defecator, or the vessel in which this 

 operation is conducted, may be of wood. Copper is perhaps the 

 best material, but is much more expensive. The vessel should 

 be furnished with a steam cod, with sufficient capacity to heat the 

 juice to the boiling point in a short time. As soon as the juice 

 is expressed it should be removed to the defecator, where it should 

 be heated at once to about ITS'" F., or just about hot enough to 

 enable a man to hold his hand in the juice without being scalded. 

 Milk of lime, freed from all coarse particles by straining, should 

 then be added until a slip of red litmus paper becomes changed 

 to a faint purple when dipped into the juice. The lime should be 

 added in small portions, the jaice being vigorously stirred with a 

 paddle after each addition. When the right quantity has been 

 added, the juice must be heated as quickly as possible. A thick 

 green scum will soon come to the surface. When the boiling
