vacuum. The sugar thus obtained — after having been 

 cooled — is then put into centrifugal machines to eliminate 

 the molasses. In order to remove the last trace and so 

 to get very white sugar, the product is finally exposed to 

 a fine spray of water or steam. 



The sugar, on leaving these machines, is dried in the 

 sun or artificially and then packed in „krandjangs" (kind 

 of basket) of about 2 picols. 



The molasses obtained by the centrifugal machine 

 still contain sugar. Therefore, they are once more boiled in 

 the vacuum to pass for the second time through the cen- 

 trifugal machine after having been cooled. However, even 

 then they still contain sugar, but it is very difficult to extract 

 it. For this reason, the manufacturers let the molasses run 

 into the rivers or distil, like the Tjomal-mill, alcohol (arrack) 

 from them. 



As said above, dry leaves or the „ampas" which leaves 

 the mills is used as fuel for the machines ; sometimes also 

 wood (seldom coal). In the ovens, specially constructed for 

 this purpose, the wet ampas is used, but mostly it is dried 

 in advance in the sun. 



§ 7. The sugar-manufacturers in Java have two 

 experimental stations where trials are continually made 

 upon the culture and production of sugar by specialists and 

 learned men in the sphere of tropical agriculture. 



§ 8. On an average 11 5 picols of sugar are produced
