FIFTH TRIAL. 



The fifth and last ran of the diffusion battery was begun on January 14 and finished 

 on the 18th. This trial was made after the milling work had been completed. The 

 diffusion juices were treated precisely the same way as the mill juices had been, and 

 after passing over bone-black were concentrated to sirup in a Yaryan 'viadniple effect, 

 which has been in use with the mill juices during the manufacturing season. 



The working of all the machinery during this final trial was satisfactory, and the 

 even march of the whole work promoted the efficiency of the machinery and the suc- 

 cessful manipulation of the juice. 



TABLE No. 43. Analytical data of fifth run. 



The molasses from the first sugars being very rich, the method of reboiling to grain 

 was employed. To this end the molasses of the first strike, having been reduced to 

 55 to 60 per cent, of total solids, was boiled on a nucleus of first sugar left in the 

 pan from the second strike. In this way all the molasses was boiled to grain with 

 most gratifying results except that from the last strike of the first sugars. 



The attempt to boil this to grain did not succeed in giving a masse cuite which could 

 be dried with ease. The molasses running from the niachines-was so thick that it 

 clogged them up. Seven large sugar wagons were filled with this material and set 

 in the hot room.
