The juice in both cases was made as nearly neutral with lime as ~ 
possible. 
+ seems from the above that the invertive action of the heat has 
been greatly overestimated, and that when the juice isnot atid no... 
appreciable inversion takes place even when the juice is reduced to 
a moderately heavy sirup in an open pan. : | 
From Mr. Parkinson’s report it will be seen that the loss in leaves 
~ and sheaths amounted to about 11 per cent. of the weight of the 
* topped cane. This loss can no doubt be somewhat reduced when the 
cleaning machines become better adapted to the work. ce 
» According toa number of trials with freshly-cut cane the weight 
’ of leaves and sheaths amounted to 10 per cent. and the seed tops to 
_ ‘15 per cent. of the weight of the whole plant. Late in the season 
- when the leaves become dry this proportion is of course considerably 
less. 
& : COST OF A FACTORY. : 
is equally necessary in a small one, and the proportionate price of 
‘double the cost of a factory working 100 tons. Again, the cost of 
operating a large factory is proportionately much less. It takes no 
more men to operate a diffusion battery with a capacity of 200 tons 
of cane than one half as large, and this is true of the larger part of | 
the machinery in the factory. A point may of course be reached — 
_ where the size of the machinery becomes too large for economical  _ 
_ working, and when the amount of cane needed for working will be me 
| greater than can be grown within easy reach of the factory. Pane Fe, 
_. - Judging from our present knowledge, a factory capable of working 
from 200 to 250 tons of cleaned cane per day seems the most desirable. 
» This would require a diffusion battery of 12 cells, each cell having a 
* capacity of 112 cubic feet. The evaporating apparatus should’ have 
' acapacity of 250 tons of water per day and a strike pan with a pro-
