Who does not know of the tarred rigging that once meant so much to the rope maker? Its very odor seems to cling to the pages of seafaring books. When steam power took the place of wind power in ships the use of tarred rigging naturally declined, yet tarred goods still form an important branch of the rope business. Pine tar is the kind best suited for cordage, the yellow, longleaf, or Georgia pine holding the first rank in the United States for tar making. This tree is found along the coast region from North Carolina to Texas. In tar-kiln burning only dead wood is used, the green tree yielding less tar and of lower quality. It is a slow process, as a brisk fire would consume the wood without yielding tar. As the tar comes from the kiln it is caught in a hole dug before the outlet and is dipped up and poured into barrels, the average yield being one barrel of tar to the cord of wood. As above said, it is indispensable to protect cordage exposed to the effects of moisture, except in the case of coir ropes. Oiling is also an important process in the manufacture of ropes from hard fibers, as Manila, Sisal and New Zealand. This softens them and makes them more workable, and it also acts as a preservative. [Illustration: INSPECTING MANILA FIBER AT DOCK] [Illustration: SHIPPING PLATFORM OF A LARGE FACTORY] Why does Rope Cling Together? This is probably due to a degree of roughness in the surface of fibers, often imperceptible to the eye, yet preventing them when in close contact from slipping easily upon each other. This is greatly increased by twisting the fibers together, and is added to by the toughness of the fibers themselves, the whole giving to rope a great resisting power. In the case of wire rope it is the firmness with which the metal holds together that gives it its great resisting strength. It is also not unlikely that the pressure of gravitation takes part in rope making, by holding the fibers in close contact, even if we do not know how this force operates. What is Rope Used for? This is a question that has already been answered in great part. Its uses, in fact, are innumerable. It serves to hold things together, and also to hold them apart; to lift things into the air and to hold them down to the ground; to pull things forward and pull things back--but not to push things forward. For the latter something less flexible than rope is needed. Animals are tied or tethered by it and led by it, and man, himself, is one of its victims. This is especially the case in the dismal way in which man’s career upon earth has so often been ended by lifting him from the ground by the aid of a rope loop around his neck. It is of some comfort to know that this brutal use of the rope is being replaced by more humane methods of ending the lives of condemned criminals. * * * * * How did the Expression “A-1” Originate?
