green ? At what point will the cost of the requisite additional coal 
be compensated for by the economic circumstances attending the 
use of green megass ? Extra coal is required for supplying the defi- 
ciency of available heat units in the green megass, for producing the 
additional power absorbed by the canes in yielding a greater per- 
centage of juice, and for concentrating the additional quantity of 
juice thus obtained. On the other hand we have value of additional 
products, no manipulation of the megass, no logies, less insurance, 
immunity from the detrimental effects of bad weather upon the megass, 
etc., each and all involving most intricate calculations that prohibit the 
possibility of defining the point of financial balance between the old 
and new systems. One thing is certain, the amount of coal burned per 
ton of sugar made must increase (without improved machinery), but 
when improvements in crushing have been carried far enough to ensure 
a financial success of the use of green megass, this will no longer be 
deplorable. Estates that can boast a percentage of expression well into 
the seventies have, probably, achieved the object in view, even if they 
are not saving money by it ; but with others I am sure it must be 
otherwise. 
I do not wish to discourage those who attempt to prove the present 
degree of crushing warrants the introduction of the new system, let 
everyone do his utmost to improve the crushing and burn green megass, 
it is by their losses we shall gain experience, and ultimately triumph in 
seeing fuel accounts within reasonable bounds, and cost of manufacture 
considerably reduced ; the goal is within sight and we are moving in 
the right direction, let us therefore press forward with all possible speed.

The Campbell Memorial. — The Secretary read a let- 
ter from Mr. Walker forwarding a letter from Mr. H. H. 
Armstead, with respect to the probable cost of a bust of 
the late Mr. W. H. Campbell. Mr. Armstead stated, that 
his charge for an ordinary posthumous bust was two 
hundred guineas. In Mr. Walker's letter, that gentle- 
man stated that he was making further enquiry as to 
the charges of other artists. It was decided to wait for 
further information from Mr. Walker on this matter.
