price paid for white sugar at present prevents this branch of
commerce from flourishing. Oranges, lemons, figs, guavas,
apricots of the Antilles, (class xiii. Polyandrie monogymie,
Lin.,) pineapples of every variety, pomegranates, shaddocks,
mangoes, rose-apples, custard-apples, cachimants, cai'mites,
(Chrysopkyllum caïmît, Lin.,) papaws, sapodillas, dates,
avocates, and the other luscious fruits of the Copies, — all of
which are to be found in Hayti,—would furnish unfailing and
abundant sources of wealth in this department of industry.
Another lucrative commerce, awaiting development, is that
of extracting perfumes from flowers. Thousands of frangy-
panni, jasmines, vervaines,—all the innumerable flowers of the
tropics, — now literally waste their sweet perfumes on the
desert air, for the want of a proper knowledge of the methods
of saving them. There are no fine essences and perfumes sold
in the civilized world that could not be manufactured in Hayti.
