Rope
This is because of our knowledge that a high-grade rope can be
produced, with the proper facilities, to sell at a price relatively
lower than one made from cheaper materials. This, of course, because
the advantages of lightness, strength and durability more than
outweigh the difference in price per pound. This is true from a
strictly dollars-and-cents standpoint, to say nothing of the greater
satisfaction in using the better article.

The making of cheap Manila (or so-called Manila) rope has been carried
to such an extent that recently signs of a reaction have been apparent.
Writers in trade journals are protesting against the lengths to which
the cheapening of rope is being carried; buyers are learning that
quality and economy are close companions in the rope trade; and so the
correctness of our position is being more fully demonstrated every day.

CHAPTER II
SISAL FIBER
The American cordage manufacturer is an importer; very little of the
fiber entering into his product is grown at home. We have already
seen how the principal cordage fiber--Manila--is brought from the
Philippines. Fiber is also imported from Russia, from Italy, and from
New Zealand, but we wish to speak now of the material which, next
to Manila, is most used in hard-fiber cordage--Sisal--and which is
secured from one of our nearer neighbors. This fiber is obtained from
the leaves of a cactus-like plant belonging to the _Agave_ family.
While varieties of this plant grow in many parts of the world, it is
cultivated most extensively in Mexico, the state of Yucatan being the
chief center of production and Merida the capital of the state the
principal market. Several railroads connect Merida with its seaport,
Progreso, whence the fiber for export is shipped.
As Sisal more than any other fiber is used as a substitute for, or
competitor of, Manila, we may make a brief comparison of the two.
The length of Manila fiber is usually from six to ten feet, while that
of Sisal is only from two to four feet. The tensile strength of Sisal
is not more than three-fourths that of Manila.

The color of Sisal is quite attractive, being a yellowish white, with
sometimes a slight greenish tinge. Some fine lots of the fiber are
very nearly white, but it all lacks the gloss and brilliancy which are
characteristic of good quality Manila.
Manila is noted for its smoothness and pliability, which make it an
ideal fiber for rope-making. Sisal, on the other hand, is without
this flexibility, and is much more stiff and harsh. This accounts for
the presence of the unpleasant “splinters” in a Sisal rope, and their
appearance in so-called Manila rope is an indication of the use of
Sisal as an adulterant. Sisal is also more easily injured by exposure
to moisture and varying atmospheric conditions than Manila.
