The most complete rope-making machine yet reached is that in which these two machines are combined into one. It economizes space, machinery and workmen, and also is more rapid in reaching the final result. But there are disadvantages which render it unfit for the larger sizes of rope, and it is therefore used only on a limited range of sizes.
American Hemp.
Among the fibers employed in rope making that of the hemp plant long held the supremacy, though in recent years it has been largely supplemented by other and stronger fibers. This plant is a native of Asia, but is now grown largely in other continents, taking its name from the country in which it is raised, as Russian hemp, Italian hemp, and American, or Kentucky, hemp, it having long found a home in the soil of Kentucky. It differs from the Manila fiber, which has now very largely supplanted it, by being much softer, though of less strength. In the old days of the sailing vessel hempen rope was largely used for the rigging of merchant and war ships, but the use of other fibers and of wire for rigging has greatly reduced the market for Kentucky hemp. There are various other fibers known under the name of hemp, the New Zealand, African, Java, etc., but the Manila and Sisal fibers, since the middle of the last century, have largely taken their place.

Manila and Sisal Fibers.
Manila hemp, as it is called, is a product of our Philippine dependency, being obtained from a species of the banana plant which grows abundantly in those islands. Its fiber is very long, ranging from six to ten feet, and is noted for its smoothness and pliability, a feature which makes it ideal for rope making. Gloss and brilliancy are also characteristics of good quality Manila.
