could be obtained in the cell. Further trials, however, of this process 

 on sorghum are needed to decide fully upon its efficacy. 



Since glucose was so largely in excess of sucrose no attempt was made 

 to obtain sugar. The sirup was concentrated into molasses and sent to 

 the molasses-tank. 



CONCLUSIONS. 



While the present season was in Louisiana a most disastrous one for 

 making sugar from sorghum, yet the suscessful application of diffusion 

 in the extraction of the juice from both sorghum and sugar-cane has 

 been abundantly pro.ven. 



From sorghums of fair quaility, such as were raised on this station in 

 1S8G and 1887, it is certain that a large quantity of sugar could be ob- 

 tained. From Early Orange this year with only 7 per cent, sucrose and 

 3.33 per cent, glucose (glucose ratio nearly 50), 31.4 pounds sugar were 

 obtained to ton of sorghum. This same variety showed in 1886 a sugar 

 content of 13 per cent., with a low glucose ratio, and in 1887, a less fa- 

 vorable year, sugar content of 10.5 per cent, and only 13 as the glucose 

 ratio. Could such cane have been diffused this year, a yield of fully 100 

 to 125 pounds per ton might with reason have been expected. 



However, the station will repeat again the experiments next year, with 

 more promise of success.
