LOVERING’S EXPERIMENTS. 11 
duced from 18,148 canes, yielding 1,737 gallons juice, weighing nine 
pounds per gallon, or 15,633 pounds, being four per cent. of sugar 
and 9.50 per cent. of molasses, or 13.50 per cent. together. 
This sugar is of a yellowish brown color, about as dry as, and about 
the color of second quality Cuba sugar, such as is used by refiners. 
(See sample No. 2.) 
THIRD EXPERIMENT. 
Oct. 23, The foregoing favorable progress induced me to make 
oe ss, another trial, on a larger scale. The weather looked 
Foggy. threatening, and as a precaution, I cut five hundred feet 
of canes, and stored it in the barn, to be used in quantities conforming 
to my means of working. 
Nearly a month having elapsed since the first polariscopic observation 
was taken, and two weeks since the second practical experiment, having 
had several heavy white frosts, and three nights of ice, one eighth to 
three sixteenths of an inch in thickness, I concluded to have another 
examination by polarized light, to see the effect of these changes, when 
I was gratified to find the following results; juice weighing full 10°

First observation, right, 55° ° 
Add ten per cent for dilution, 5°.5 60°.5 right. 
After inversion, 2° 2 90 
Add ten per cent as above, 0°.2 temperature 25° 2°.2 left. 
Sum of inversion, 62°.7 
This sum of inversion, (62°.7,) at temperature 25°, indicated 79.06 
grammes of sugar per litre of juice; then,
