182 VALUE OF SORGHUM IN SUGAR PRODUCTION. 
In some cases the mass of crystals deposited equaled in 
volume the clear syrup above them from which they had 
separated. For the reason that the condition of the syrups 
at the time they were sent to the laboratory at Washing- 
ton could not, in many cases, be ascertained; in the analy- 
ses no account is made of the sugar which had been de- 
posited in this way; but in the table inserted in the Report 
only the amount of cane and uncrystallizable sugar in solu- 
tion at the time the analysis was made, is made to appear. 
The necessity which led to this arrangement is to be re- 
gretted, for some true syrups of drainage (molasses) from 
which the greater part of the sugar had already separated 
are here compared side by side with others which were 
known to contain all their original sugar. But it is worthy 
of note that specimens which had previously deposited a 
mass of crystals equal in bulk to half the length of the 
bottle which contained the syrup, still contained a very 
large per cent. of cane sugar,—in one instance, 35°62 per 
cent. of cane and 28°11 per cent. of uncrystallizable sugar. * 
%* No. 7. White imphee syrup, uncryst. sugar, 28-11 per cent.; crystal- 
lizable sugar, 35°62; water and impurities, 36-27 100-00. If to the 
35°62 per cent. of cane sugar, we add the “sediment of light-colored 
crystals of cane sugar extending half the length of the bottle,” which 
may be inferred to have amounted to near 50 per cent. of the whole 
contents of the bottle by weight—say 45 per cent., the 55 per cent. of 
clear syrup, analyzed, contained:

Hence this syrup originally contained 64°59 per cent. cane sugar, and 
15°46 unerystallizable. It may be inferred that a part of the 15°46 per 
cent. is sugar reduced to an uncrystallizable condition by the action 
of heat. The original per cent. of uncrystallizable sugar must have been 
exceedingly small and the juice of great purity.
