The _New England Grocer_ says that the manufacture of molasses is
really the manufacture of sugar up to a certain stage, for molasses is
the uncrystallized sirup produced in the making of sugar. The methods
of manufacture in the West Indies vary very considerably. In the
interior and on the smaller plantations it is made by a very primitive
process, while on the larger plantations all the appliances of modern
science and ingenuity are brought to bear. Each planter makes his own
sugar. It is then carried to the sea coast and sold to the exporters,
by whom it is shipped to this country. The quality and grade of the
molasses varies with each plantation. Two plantations side by side may
produce entirely different grades. This is owing to the soil, which in
Porto Rico and other localities in the West Indies seems to change
with almost every acre. The cane from which the sugar and molasses is
made is planted by laying several pieces of it in holes or trenches.
The pieces are then covered with earth to the depth of two or three
inches. In about two weeks sprouts appear above the surface. Then more
earth is put in, and as the sprouts grow, earth is added until in
three or four months the holes are filled up. The planting is done
from August to November, and the cutting progresses throughout the
greater part of the year. The cane grows to a height of seven or eight
feet, in joints each about a foot long.
When the cane is in proper condition for cutting, as shown by its
appearance, an army of workmen take possession of the field. Each is
armed with a long, broad knife, like a butcher's cleaver. They move
down the lines of cane like an army, and while the cutting is going on
the fields present an interesting sight, the sword-like knives
flashing in the sun, the 300 or 400 laborers, the carpet of cut cane,
the long line of moving carts, and the sea of standing cane, sometimes
extending for miles and miles, stirred by the breeze into waves of
undulating green. The laborers employed on these plantations are
largely negroes and Chinese coolies. When the cane is ripe, they
proceed to the field, each armed with a _matchet_. Spreading over the
plantation, they commence the cutting of the cane, first by one cut at
the top, which takes off the long leaves and that part which is
worthless, except as fodder for the cattle. A second cut is then given
as near the root as possible, as the nearer the ground the richer the
cane is in juice. The cut cane is allowed to fall carelessly to the
ground.
Other workmen come with carts, pick it up, tie it in bundles and
carry it to the mill. The cutting of the cane is so adjusted as to
keep pace with the action of the mill, so that both are always at
work. Two gangs of men are frequently employed, and work goes on far
into the night during the season, which lasts the greater part of the
year.
