Wire Rigging for Ships
Wire rigging for ships: - The Liverpool Courier says three-fourths of
all the ships now fitted out of Liverpool are rigged with wire rope. It
is described as a fourth less in weight, and not on-half the bulk of
that made of hemp, and the cost is also 25 per cent less. It is much
less susceptible than hemp of atmospheric changes, and it is predicted
that in a few years it will supersede hemp rope for standing rigging. A
recent trial of wire, hemp and Manilla ropes was recently made at the
King's dock, Liverpool. The straining tests showed the immense
superiority of wire rope over that made even of the best fibrous
material. The testing of the hempen ropes proved the strength of
Manilla to be far superior to Russian hemp, taking many of the
merchants, shipmasters and riggers present by surprise, as a different
opinion had been entertained by many of the gentlemen present.

The English have the advantage of us in regard to iron ships was well
as wire rigging, on account of the cheapness of material. Iron ship are
increasing in number in England, and in many respects they are superior
to wood, but they can not be built here until iron becomes cheaper. An
iron ship in England cost only about the same as a first-class wooden
ship, but in the United States would probably cost three times as much
as a wood-built ship. The depreciation on an iron ship is much less
than one of wood, and when the iron vessel is worn out, the old
material will go far towards paying for new. These are important
considerations. There is no one thing which we so much need, as the
ability to produce iron as cheaply as England. We have the crude
materials in abundance, cropping out on the surface of the earth
instead of being compelled to dig hundreds of feet deep for it, but we
need the skill and the labor which is requisite.
