-. in both color and flavor to the sirup from the mill juice. The juices 
- from the mill and battery were treated precisely alike*stnd they were 
skimmed and evaporated in an open steam evaporator. This is a 
“matter of great importance to all engaged in the sugar business, as

_ able cane that is not-fit for sugar-making, and the fact that 25 gallons 
of first-class sirup can be made from such cane by diffusion makes 
- it possible to work even such material at a good profit.

was added. It was then filtered. To other portions of juice, instead | 
of carbonate of lime, 3 per cent. of ground shale, bituminous coal, 
and sandy loam were added respectively. The filtrations were very

_. On August 30 the first strike was made, and the yield was a little 
more than 100 pounds of washed sugar per ton of clean cane. 
ee INVERSION OF CANE SUGAR. 
an i 
To prevent the inversion of the sugar in battery, about 10 pounds of 
dry precipitated carbonate of lime was mixed with enough water to pro- — 
- duce a thin paste. This was added to the fresh chips while the cell 
“was being filled, and entirely prevented any loss of sugar by inversion. 
The carbonate was made by forcing carbonic acid gas by the aid 
- * of a pump into thin milk of lime. The injection pipe was perforated 
~ and lay along the bottom of a 10 by 10 foot tank containing the milk 
of lime. The gas was produced by burning coke in a small furnace.- 
+*- When the lime showed but a slight alkaline reaction it was run off 
into a large hole in the ground where the water soon drained away, 
leaving the carbonate nearly dry. 
EXPERIMENTS WITH DEFECATION. 
: On September 1 filtration was dispensed with and experiments tried 
with simple defecation. The defecators were similar to those In
