New System OF NIanufnc turing Sugar.

We have been favored (says the London
Tirss) with opportunity OF witnessing an improved
process for making sugar recently invented and put In
operation by Mr. H. Bessemer, civil engineer at hs pre-
mises Baxerhouse, Old st. Paneras road, and, In com
mon with several gentlemen practically conversant with
the subject who present. have 70 express the high
qualification experienced the results under
notice. In tho present condition OF our West inda
colonies every Improvement in the manufacture Of
