SMITH ON NEW PROBLEMS AND NEW PHASES OF OLD ONES. 145 



expensive and, it must be confessed, clumsy macliinery and methods of 

 manufacturing, will be displaced by simpler, more economical and more 

 efficient apparatus. I have but to refer to the experiments going on 

 in Belgium and also in Austria where, by the use of an electrolytic 

 method the crystalization of the sugar from the purified juices is greatly 

 expedited and is much more economically accomplished. 



It may be rightfully supposed that the chemicals found in nature 

 produce the same results in America that they do in Europe, but much 

 light is needed to answer the question what are the real melassigenic 

 salts? We have condemned certain chlorides and carbonates, to the 

 point of prohibiting the use of water containing them. Others we have 

 pronounced harmless. We have certainly done it without sufficient 

 authoritative experiments in this country. 



In conclusion, I refer to the desirability of improved chemical methods 

 in the factory whereby justice to the patron bringing beets may be 

 better assured and whereby the matter may be somewhat expedited.
