Rope
Who does not know of the tarred rigging which once meant so much to the
rope-maker? Its very odor seemed to cling to the pages of seafaring
books. Its use naturally declined with the development of steam power,
yet how few people, perhaps, realize that tarred goods for quite
different purposes form an important though incidental branch of the
rope business today! Lathyarn--to mention but one class--is consumed
annually by the lumber industry in quantities that would surprise many
persons. Today’s buyers, furthermore, need goods of high quality just
as did the old-time sea captains, and in the manufacture of such goods
the tar itself is an important factor.
Pine tar--the kind best suited for cordage--comes from various members
of the pine-tree family, and is secured by a distillation process. The
principal producing sections are northern Europe and the south-eastern
United States--the yellow, long leaf or Georgia pine, which ranks
first in this country for tar-making, growing in a territory about one
hundred and twenty-five miles wide along the coast from North Carolina
to Texas.

Of the two methods for extracting the tar--the old kiln and the modern
retort processes--the second yields the greater supply, largely because
of the more systematic manner in which the industry is carried on. As
yet, however, no way has been perfected for obtaining by this newer
method a tar that measures up to Plymouth Cordage Company standards,
and for this reason we have continued to use the kiln-made article only.
Tar-kiln burning is conducted so far out in the country and in such
a desultory fashion that few people have the opportunity to become
acquainted with the process. A brief description may, therefore, be of
interest. Only dead wood is used, as the green tree does not yield the
quality or quantity of tar necessary to make the work profitable. Among
the tar-makers the material is known as fat lightwood, possibly from
the fact that it ignites easily and burns rapidly. In weight and color
it is anything but a light wood.
The wood is cut into convenient lengths and then laid up, with the
ground as a floor, to form a pile about twenty-five feet long by five
high and tapering in width from eight to five feet. The soil, if soft
or sandy, is first covered with clay to lessen the loss of tar, and the
pile is usually built on a slope so that the liquid will flow toward
the pipe which serves as an outlet.
