The most important obje& to the planter, next to 
increasing the produce of his land was improvement in 
the manufaéture of sugar, and it was gratifying to them 
to be able to report that most of the planters were — 
keeping this objeétin view. Recent events would,itwas 
expected, stimulate them to greater exertions, and those 
estates which had already ereéted or were then ereéting 
vacuum pans would no doubt find it to their advantage 
to persevere in manufa€turing sugar by this method. 
The application of steam to the evaporation of cane 
juice was understood beyond a doubt to be attended 
with success, and by this means a great deal of the megass 
then used for fuel under the coppers might be returned 
to the fields and used to renovate the land and make it 
more produétive. The excellent, but rather expensive 
apparatus of DEROSNE & CAIL, they understood was about 
to be introduced on one or two large estates, whose 
proprietors were in a position to bear the outlay. 
They recommended an examination of the merits of 
RONALD’S (of Glasgow) Steam Chest at Pln. Profit 
which appeared to be very moderate in cost. It was 
only used as an auxiliary to enable an estate to make a 
larger quantity of sugar per day than could be produced 
by coppers alone, but there was little doubt that by its 
use a considerable saving of sugar and labour might be 
effe€ted at a small cost, and the sugar was said to be 
improved in quality. The Society had been favoured 
with several communications from Mr. OSBORNE on the 
subje&t of hydraulic pressure for expressing cane juice, 
but they understand that this method had proved ineffi- 
cient in some of the neighbouring colonies, and no one 
here was likely to venture on the experiment. Mr.
