From these we see that the cane sujiar gradually and rapidly increased, 

 while the glucose slowly decreased, from the time of flowering to the matur- 

 ity of the seed. During the latter part of September, most of the cane was 

 lodged by a very violent wind and rain storm. The juice from the stalks that 

 were lodged was charged with a red coloring matter, the inside of the entire 

 stalk being in many cases of a bright red color. Several of the stalks con- 

 tained but a small portion of red coloring matter, but instead had a peculiar 

 yellow and watery appearance, and quite a disagreeable taste. The juices 

 from these contained on an average only 8 per cent sugar, and 4.8 per cent 

 glucose.

Maine Beet Sug.\r Company, 5 Park St., Boston, December 7ih, 1882. 

 To the Cane Growers Association, Si. Lota's, Mo. 



Gents — Having been a sugar refiner, and, more recently, the treasurer and 

 managing director of the Maine Beet Sugar Company, which made in two years 

 (1879 and 1880) $200,000 worth of sugar and syrup from beets, raised in New 

 England, I desire to make some practical suggestions for the manufacture of 

 sugar from sorghum. I have recently become convinced, by the experiments 

 of Prof Collier, of the U. S. Department of Agriculture, Washington, D. C, 

 that the juice of well matured sorghum is equal to that of the sugar-cane. 

 This summer, I raised an experimental crop of "Early Amber" and "White 

 Liberian," from seed obtained at Washington, in my garden here in Boston. In 

 the last week of October, I cut this caae, fully matured, and still uninjured by 

 frost. The juice gauged 11° Baume, when clarified, and proved so fine that I 

 had it analyzed by S. P. Sharpless, state assayer, 114 State street, Boston, with 

 the following result:

This juice had been defecated by lime in excess— the lime being mostly pre- 

 cipitated afterward by phosphoric acid. The "Ash" indicated above was 

 largely lime and phosphate of lime held in solution, the result of defecation. 



This being fully equal to average West India juice. I made a few pounds of
