The differences between the results OF these

In conclusion, 1t may be that those expert

are suggested nj least. and may bear good fruit
hereafter by directing attention to the import

printed IN pamphlet form for distribution.
Some discussion on tho matters contained in
1t ensued but no further action In reference to
the subject was taken.
The following, offered by Gen. j. S. Brent, was
RESOLVED Thatthe secretary be directed to ap-
ply to all planters who weigh their cane for
showing
First-The percentage OF juice obtained from
cane, assuming the Juice to weigh go pounds to
he ga Ion
Second-The percentage of yield In dry
sugar.
ThtrG-Ihe percentage Of yield In moasses,
moasses to weigh twelve pounds per
gallon.
Fourth-The total percentage OF saccharine
results.
Resolped That the planters be requested to
prpsent such statement, embracing as many |
years as they have weighed their cane.
