Rope
The cultivation of the _heniquen_ is now carried on principally upon
large farms or plantations known as _haciendas_, many of which have
made their owners enormously wealthy. In starting a field of plants
the suckers or _hijos_ are set out in rows, and cultivation is carried
on once or twice a year to keep down the weeds. The appearance of the
fields of Sisal and of the growing and matured plants may be seen from
our illustrations. When the plant has been growing about five years
some of the long, sword-like leaves will be ready to cut, those around
the base of the plant maturing first. The time for cutting is indicated
by the leaves assuming a nearly horizontal position instead of the more
upright one of the younger leaves, at which stage the fiber is at its
best. Then the natives, with their _corbas_ go through the fields and
cut off the matured leaves, trim the sharp thorns from the sides and
ends, and tie up the leaves in bundles of fifty, ready to be carried to
the cleaning mill.
The plant continues to yield a supply of leaves for a period of from
ten to twenty years. The end of its usefulness is marked by the
appearance of the flower stalk or “pole,” and the plant soon dies.
[Illustration: CLEANED FIBER COMING OUT OF CLEANING MACHINE]
Most of the large _haciendas_ are supplied with portable tracks, and
small cars carry the bundles of freshly cut leaves from the fields to
the cleaner house, where the pulp is scraped from the fiber by the
powerful cleaning machinery.
[Illustration: SISAL DRYING]
As will be seen in the photographs, the bundles of leaves are taken up
on an elevator and along a carrier, which feeds them into the machine.
The grip chains of the carrier hold the leaves, while the scraping
wheels clean the pulp from the fiber, first one end of the leaves being
cleaned and then, as they are carried farther along, the second wheel
cleans the other end. This leaves the bundles of the fiber still in the
grip of the carrier, which takes it out of the machine as shown in the
picture. It is then carefully hung in the sun to dry. When thoroughly
dry the fiber is taken to the press and made into bales weighing about
370 pounds each.
We have already mentioned the fact that Manila rope is frequently
adulterated with cheaper and inferior fibers, and so Sisal in its turn
has its inferior imitators, the most common of which is known as Istle,
a fiber which also grows in Mexico as well as in other parts of the
world. A recent government publication, speaking of the use of Istle in
cordage, states, “this fiber has been regarded heretofore as suitable
only for use in the _manufacture of brushes_.”
