The 20 per cent solutions by the Molhant process have a yield 

 equal to the maximum obtained by the regular method. The 

 results for high concentrations up to 25 per cent molasses solu- 

 tions are uniformly good. In every case they are above 80 per 

 cent, the percentage yield that is considered good distillery prac- 

 tice. In fact, the average percentage yields are higher than 

 85 in each case, and the consistence of the results and the sim- 

 plicity of the process make it a valuable method. In the dis- 

 tilleries using nipa juice and molasses the custom of mixing nipa 

 juice with molasses solution in making up the ferment is followed. 

 This is a modified Molhant process, where the nipa juice carries 

 the yeast. Such mixtures usually give excellent results in the 

 early part of the nipa-juice season, but after the middle of the 

 season yields from such mixtures decrease and often become so 

 bad that the use of nipa juice must be discontinued. An inves- 

 tigation 21 by the Bureau of Science shows that the loss of the
