Men are sometimes set to work tramping upon sacks filled with rab, in order to separate the syrup from the sugar; again sacks of rab are piled upon a floor with holes for drainage and a well for the syrup that runs off. Weights are often placed upon the bags in order to hasten the process. After the drainage is fairly complete, the rab is dumped into vessels having openings at the bottom and covered at the top by a layer of wet water plants. The water as it passes through the mass of sugar washes the syrup from the crystals and the liquor runs off through the apertures in the bottom. Several days afterward the operation is repeated, and so on until all the syrup has been removed by washing. The resulting sugar is either used in that form, or dried in the sun and worked by human feet in order to lighten its color.
Saiyid Muhammad Hadi, assistant director of the Land Records and Agriculture at Allahabad, has worked out an improved method for making rab which is now widely adopted. Under his plan the furnace heat can be readily controlled, so that the danger of burning the juices during boiling is considerably lessened; neither is there so much risk of decomposition (souring). Besides, the cooled rab is purged of its syrup in a centrifugal machine worked by hand instead of by drainage from wet vegetation. At best, however, the production of sugar by the natives of Hindustan is still at a very elementary stage, and in that country new ideas gain ground very slowly, so that it will be some time before modern machinery and equipment are generally in use.
It would seem that in view of the small production of sugar per acre and the enormous losses in manufacture, a modern plant, with machinery of the latest and best type and large financial resources, should be remarkably successful, but such is not the case. It appears to be impossible to get a steady supply of cane. In India, plantations like those found in other countries do not exist. Instead, there are a great number of extremely small pieces of land all under different ownership. The cane has to be brought to the mill from considerable distances in small quantities, and owing to lack of intelligence or initiative on the part of the farmer it is of indifferent quality. Transportation facilities are far from good and the manufacturers have to make up the shortage in the supply of cane by using rab and gur. If the latter should contain an excessive amount of glucose or be caramelized, it does not lose its value as an article for direct consumption; on the other hand, either of these conditions unfit it for the purposes of refining, and as there is but a slight difference in price between gur and the white sugar into which it is made, the disadvantage to the refiner is readily apparent. Another drawback is that the Hindus do not take kindly to sugar manufactured by the European process, consequently chini, or sugar made from rab by the native method, commands a better price than, sugar made in a modern refinery. Religious and caste prejudices exert a strong influence also. In modern sugar refining, animal charcoal is the principal purifying and decolorizing agent, and this, together with the fact that ox-blood has been used for clarification, causes the Hindus to reject sugar prepared by such means. Finally, there is the apprehension on the part of the high-caste natives that the sugar may have been produced by low-caste labor and that to eat it would bring defilement.
The refiners of India have begun to recognize the advantage to them in using raw European beet-root sugars and raw cane from Java and Mauritius instead of the more costly preparations of rab and gur. As a result, there is a considerable quantity of foreign sugar imported into India which is consumed ultimately by the high-caste native without his being aware of its origin.
The imports during the period from 1908 to 1916 were as follows:
| 1908-09 | 535,664 | tons of | 2240 | lbs. |
| 1909-10 | 556,840 | ” | ” | ” |
| 1910-11 | 608,785 | ” | ” | ” |
| 1911-12 | 508,591 | ” | ” | ” |
| 1912-13 | 675,017 | ” | ” | ” |
| 1913-14 | 802,978 | ” | ” | ” |
| 1914-15 | 428,595 | ” | ” | ” |
| 1915-16 | 515,909 | ” | ” | ” |
Of this tonnage, Austria supplied the greater amount of the beet, Germany the remainder, while the cane came from Java and Mauritius. In 1913 and 1914 the raw beet from Austria and Germany was almost entirely displaced by washed Java raws, the trade name for which is “Java white.” Some sugar is exported, but the quantity is insignificant.
