the persons engaged in the operation, it is ordinarily much 
cleaner than the foreign muscovado sugars, which are prepared 
usually by persons stupid and unclean, in the midst of insects 
and of decaying vegetation. It is desirable, therefore, that its 
product should be increased; especially as it is made ata sea- 
son of the year not occupied by other rustic employments, and 
from trees whose presence along the borders of cultivated lands 
is a shelter, a protection and an ornament to the fields which 
they skirt.

continue of a light green, until the outer bark begins, in a year 
or two, to yield and cleave, the cellular substance showing itself 
white within, in longitudinal lines, which, afterwards turning 
brown, give rise to the beautifully striated appearance charac-
