The term rope is usually confined to the larger species of cordage, such as ex- ceed one inch in circumference, though the principles of manufacture are the same for all kinds of cordage. The materials used in- clude Manila hemp, flax, cotton, hemp, jute, sisal, coir, and other vegetable fibres. These are spun into yarn by machines resembling in principle those used for spinning cotton. A dozen of these yarns may be 'laid' to- gether by machine, to form a small strand called twine, and three or more strands be similarly laid together to form a small cord. For rope making the same operations are performed, but with a larger number of yarns to the strand. The first machines for rope making were used in England in 1820; while thoroughly practical machinery was first em- ployed in Massachusetts in 1834. Since that time many improvements have been made, and American rope-making machinery is used all over the world. Rops, Felicien (1833-98), Belgian painter and etcher, was born in Namur.
