The list does not end. There are incline railways, in the mountains of
East and West alike, as well as in foreign countries, which have made
mountain climbing a primitive form of sport, and enabled one-legged men
with perfect ease to get the view from towering peaks which otherwise
would have been accessible only to the hardy mountain climber; there
are cable railways with which engineers have been able to run cars out
on an aerial roadbed of wire, over impassable gorges and morasses, to
make fills for railway or other construction; cableways, the forms and
uses of which, in transferring materials, are without number; tramways
and traction systems, which have now, save in particular instances,
given way to trolley, and the copper wire for this, again, comes in
large and continuous tonnage from the Roebling mills; there is the
perfect litter of hoisting slings, all over creation, for wherever men
are doing work or business of any kind, there is a load to lift, and
the wire rope, with its special appliances for quick hitch and release,
is fast relegating the old time chain to the category of antiquities.
In 1862 the first of elevator ropes was made. Today millions are in use.

It is a long story, and one variety of rope is never just like another,
save for the general purpose product before referred to, which figures
in the schedules as "Standard." But in the making of all the many
hundred kinds, the process, to outward appearance, is the same, and
impressive in the simplicity to which it has been reduced. From the
tiny specimen, made for some finical scientific experiment, to the
three-inch monster that contains single wires nearly a quarter of an
inch in diameter, and drags half a million pounds of ore, with the aid
of powerful machinery, at the Spanish American Iron Company's mines in
Cuba, the general principle of manufacture and the mechanism used in
the making are all alike.
[Sidenote: ROPE-MAKING MACHINES]
In the several rope mills of the Roebling works are a large number of
machines, some of which, built by John A. Roebling in the early days of
his rope making, are still turning out rope, and good rope. His first
product was made by hand in the old "rope walk" way. Today the ground
where he did it is covered with buildings full of speeding machinery
that has little rest--devices that stand in long rows, eating up the
strand that unwinds from the whirling bobbins to feed it, and turning
off steadily the completed rope, which passes to spools, large or
small, in proportion to its weight and size.
