done in the furnace ; the pity is that so large a waste is 
necessary to get rid of the combined water. 
As it has been asserted that the contained sugar left 
from bad crushing is more than enough to drive away 
the combined water, in fact that badly crushed megass 
makes better and stronger fuel than when the straw has 
been denuded of all its sugar, I made a few trials on the 
same furnace, No. i, with megass from the first mill, 
with 56 per cent, crushing. The fuel used contained 
per 100 : 
Sugar 12 = 5*04 Carbon. 
Fibre 24 12" „ 
Water 64 
100 = 17*04 
Taking this carbon and multiplying by 4/5, we have from 
the value of green megass as ascertained above, 76*68 
pounds of water, which pro rata this carbon ought to 
eliminate, leaving 12*68 only for useful effect; instead 
of this being the result, although the fire brick furnace 
was a cherry heat when the stoking commenced, in less 
than a quarter of an hour the furnace turned black, 
combustion ceased, and the fuel simply smouldered.
