Market conditions make this certainty of the quality of the 
product a consideration of great importance. During peri- 
ods of sugar shortage, the poor sugars are easily sold, but, 
when centrifugal sugars can be bought at a reasonable price, 
the refiners no longer care for the native type of sugar regard- 
less of its quality. The yield decreases and the cost of refining 
increases with a decrease in purity, and the refiners prefer to 
pay a slightly higher price for sugar which can he refined 
without difficulty and give good yields, rather than work up 
poor material with their higher grade products. Furthermore, 
it becomes more and more difficult for them to dispose of the 
raw molasses as the sugar content and purity of the sugar 
refined decreases. 
In view of these facts it appears that the installation of cen- 
trals throughout these Islands is greatly to be desired from every 
point of view, and, as the cost of installation is small compared 
with the benefits obtainable, we heartily indorse their erection 
and use. An estimate of the cost and installation of a central 
factory designed to deliver 160 piculs of sugar per day, with 
cost of maintainance for a one-hundred-day campaign is briefly 
as follows:
