composition varies according to the solid and the altitude in 
which the lime is grown, the products to be extracted are as 
follows : — 
Lime juice to be shipped as raw juice, or as cordial lime 
juice, or as concentrated lime juice, used in England and 
America to manufacture citric acid. 
Essential Oil of Lime shipped to England and used by per- 
fume manufacturers.

The extraction of lime juice in a factory especially put up 
for that purpose ought to have a steam three roller mill, an 
hydraulic press to obtain the balance of extractible juice 
from the pulp after leaving the mill, a still to extract the 
essential oil from the expressed lime juice, and lastly a 
Battery of copper tayches to boil the juice if it is to be manu- 
factured into concentrated’ lime juice. The extraction of oil 
can be made also by hand, worked by the Sicilian process which 
will make an oil of a better quality but in a smaller quantity. 
The oomplete process to manufacture lime juice and 
essential oil is as follows. The limes are collected from the 
fields and accumulated near the mill, where they are passed 
through the rollers, the juice being collected from the mill bed, 
and forwarded to the still. The pulp from the mill is forwarded 
to the hydraulic press which completes the extraction of the 
juice, and essential oil remaining in the pulp. The juice from 
the hydraulic press is forwarded to the. still, and there mixed 
with the first juice as received from the mill, then the juice is 
boiled in the still, delivering during its ebullition some water 
from the juice and essential oil, after about one hour’s boiling 
all the essential oil has passed through the condenser and is 
received in jars ; then separated after a certain time from the 
water from the condensed liquid which had passed through the 
condenser. The juice remaining in the still is forwarded to the 
copper tayches where it is boiled to make concentrated lime 
juice. Cordials are made with the first raw juice from the mill 
and require special preparation. In a well equipped factory the 
manufacture of lime juice is a paying concern, but the first con- 
dition to success is to have enough limes and a complete well 
equipped factory with all the implements required. After the 
lime and orange industries we come to an entirely new industry 
for Trinidad which is that of tlje India Rubber. The plants 
uinishing rubber are legion, but as we are supposed to work for 
1 generation, leaving to the future the care of itself? 
the difficulty of forming such a plantation is the choice of the
