‘16 SUPPLEMENT. 
ficult, the color many shades darker, the juice gradually fell off in 
weight from full 1¢° Beaume to 9° Beaume, and required ten fect of 
granulated black to bring it to the same color as that made six days 
previously with five feet black. I however proceeded (keeping this 
separate) to the crystallization. 
Boiled it to 242° Fahrenheit, when it produced good, hard, sharp 
crystals ; but finding the quantity, by measurement, had decreased 
very considerably, I took no further note on that head, but gave it 
white liquor until it was neat, (about the usual quantity,) and pro- 
duced the sugar, (Sample No. 5,) being white sugar, directly from the 
cane, without refining or re-melting. 
SIXTH EXPERIMENT. 
November 27. Since the canes for the fourth and most successful ex- 
periment were cut, on the 6th inst., the weather has been very 
changeable. We have had warm indian summer weather, with heavy 
rains, also very cold weather, making ice two inches in thickness— 
thermometer having varied from 16° to 60. To try the effect of these 
changes, I cut one hundredth part of an acre, which produced il 
15-16ths gallons of juice only, instead of nineteen or twenty gallons, 
as before. It had, however, regained its former weight of full 10° 
Beaumé, but was much more acid, rank, and dark colored than pre- 
viously. It clarified without difficulty, but raised a much thicker 
and denser scum, and when concentrated, was very dark and molasses- 
like ; it however produced good, hard, sharp crystals, but the quantity 
being much reduced, there was no inducement to pursue it further. 
This experiment proves, however, that this cane will withstand very 
great vicissitudes of weather, without the entire destruction of its 
saccharine properties. 
SEVENTH EXPERIMENT. 
Took the proceeds of the experiments that were considered failures, 
viz., all the third and the poorest portion of the second, viz. : thirty- 
four pounds very indifferent sugar ; refined it in the open kettle, by the 
old process, and produced fifteen pounds loaf sugar, (Sample No. 7,) 
which is a very full yield for the quality used.
