annum, yielding at each crop from 10 lbs. to 20 lbs., according to the
nature of the soil. It will continue bearing for twenty years; but, as
it is a delicate plant, it suffers from drought, and is liable to
blight. In these respects, however, it does not differ from many other
plants, which are even more subject to disease, though not half so
valuable. Besides, a proper system of irrigation, such as could be had
recourse to in many parts of Jamaica, would obviate and prevent these
evils.

The whole quantity imported into the United Kingdom from the West
Indies and British Guiana during the last thirteen years, has been as
