VARIOUS USES OF MOLASSES. 295 



40 tons to the hectare (16 tons to the acre). If we assume 

 that from the beets at the factory there is obtained 2.5 per cent, 

 molasses,- the said 2.5 hectares, admitting only J is cultivated in 

 beets, will furnish 625 kilos of molasses, which each animal 

 will have at its disposal. This corresponds to 1.7 kilos of 

 molasses per diem during the entire year, which may be readily 

 consumed. 



But it must be noticed that one does not always obtain 40 

 tons to the hectare, and furthermore, that the four-years' rota- 

 tion is not always practicable. It frequently happens that one 

 cow is fed from two hectares. Under these circumstances the 

 farmer would have at his disposal only 500 kilos of molasses 

 per annum, meaning an allowance of only 1.250 kilos per head 

 and per diem. 



However, from what has just been said, it is evident that 

 only under exceptional circumstances one is unable to utilize 

 all the molasses that results from regular farming; that is 

 furnishing the beets to the factory and taking in return 

 residuum, pulps and molasses. 



Efforts have been made during recent years to use this Various uses 

 residuum for the preparation of certain chemical combinations. * J 

 Numerous modes have for many years been introduced for the 

 working of molasses in sugar factories, but have not given th< 

 results hoped for. 



Various means have been resorted to with a view of increas- 

 ing the consumption of sugar and molasses. Among these may 

 be mentioned molasses soap; a special introduction for dyeing: 

 also the idea proposed by Vincent, for the manufacture oi 

 ammonium chlorid and methyl chlorid; the object in view 

 having been to create an excessively low temperature. The 

 methods of Franck and Nycander for the production of fer- 

 ments may also be mentioned, and those of Schering for the 

 manufacture of levulose. 



It may seem astonishing, but the facts prove that the only 

 molasses utilization that has great practical value, when allow- 

 ing for its low selling price, is as a feed. This has not received 

 the attention from the agricultural authorities that it justly 

 deserves.
