174 VALUE OF SORGHUM IN SUGAR PRODUCTION. 
The following I have found to be average results from 
ripe cane, grown on good upland soil: 
Specific gravity of fresh juice at 60° F., 1085 or 11° Beaumé. 
Specific gravity of clarified juice at 60° F., 1070 or 93° Beaumé. 
Whole amount of saccharine matter, 17 per cent., which is cane 
sugar almost exclusively. 
How this accords with an analysis made by Dr. Charles 
T. Jackson, an eminent chemist of Boston, Mass., in the 
year 1857, will be seen in the following extract from his 
report. (Ag. Rep. of Patent Office, 1857, pages 187 and 
189.) The subject of this analysis was ripe Chinese cane. 
Specific gravity of the filtered juice, 1:062. Calculated 
saccharine matter per cent., 154. Obtained result, sac- 
charine matter (cane sugar nearly all crystallized), 16°6 
per cent.* Some imphees analyzed by him gave from 14°3 
to 15:9 per cent..of sugar (well crystallized cane sugar) 
(see table), which also corresponds closely with the per 
cent. of saccharine matter obtained from imphee by Mr. 
Leonard Wray. 
In the same Report, p. 194, Prof. J. Lawrence Smith, 
of Louisville, Ky., publishes an account of an “ investiga- 
tion of the sugar-bearing capacity of Chinese cane,” in 
which he gives the following as the composition of the 
stalk of the cane:

* An erroneous statement appears in the Report of the Department of 
Agriculture for 1862, p. 533 (table), in which the result as obtained by 
this chemist is stated to be 10°15 per cent. total of sugar, instead of 16:6 
per cent. as above. 
¢ This is equal to nearly 14 per cent. of the juice, instead of 12 per 
cent., as it is made to appear on p. 533 of the Report for 1862.
