The actual yield of sugar and syrup as above stated per 
acre is, I believe, about a fair average result—such as may 
be attained from pure cane planted upon a suitable soil, 
from the latitude of Philadelphia sduthward. But it will 
be cbserved that the yield of juice was much greater, and 
its saccharine richness proportionally much less than or- 
dinarily is to be anticipated. The expressed juice amounted 
to 1847 gallons per acre, or about one-third more than is 
commonly produced from an equal area; its density in the 
crude state was 10° Beaumé, but only 74° clarified (at 
162 F.), containing about 13 per cent. of saccharine mat- 
ter, as indicated by its specific gravity, or 12°72*per cent. 
the actual yield of sugar and molasses. Of this, 7°35 per 
cent. was crystallized sugar, 5°37 per cent. molasses (drip- 
pings). Taking into the account the 10 per cent. of sugar 
lost in reheating and footings as above stated, we should 
have of cane sugar 8 08 per cent.; molasses, 4°64 per cent. 
The molasses, however, still contained an indeterminate 
proportion of crystallizable sugar; another proportion of 
it consisted of cane sugar necessarily converted into liquid 
or uncrystallizable sugar during evaporation: hence the 
per cent. of cane sugar originally contained in the juice 
must have been considerably greater, and that of uncrys- 
tallizable sugar proportionally less than in the above 
estimate.
