than one-tenth of the
ultimate breaking strength of the rope.

To increase the amount of work done, it is better to increase the
working load than the speed of the rope. Experience has shown that the
wear of the rope increases with the speed.

Wire Rope should be greased when running or idle. Rust destroys as
effectively as hard work.

Galvanized Wire Rope should never be used for running rope. One day's
use will wear off the coating of zinc, and the rope will soon begin to
rust.

Great care should be taken that the grooves of drums and sheaves are
perfectly smooth, ample in diameter, and conformed to the surface of
the rope. They should also be in perfect line with the rope, so that
the latter may not chafe on the sides of the grooves.

+Set of Wire Rope Splicing Tools+.

To produce the best work, the splicer should have at his disposal a set
of tools similar to those in the accompanying illustration.

The Tool set consists of--1 Tucker for Small Strands Splicing; 1 Marlin
Spike, Round; 1 Marlin Spike, Flatted; 1 Pair Special Steel Wire
Cutters; 1 Serving Mallet. All of best Cast Steel, Hand Forged.

These Sets may be had at prices varying from 15/6 to 46/-.

+Directions for Splicing+.

TO MAKE AN ENDLESS SPLICE.--Clamps are applied to the rope sufficiently
far back from the ends to allow plenty of room for the splice, and the
men to operate in. The two ends are then drawn together by means of
blocks and tackle, until they overlap each other for a space of twenty
to thirty feet, according to the size of the rope. At a point from
each end midway of the lap, the rope must be bound with a good serving
of No. 18 or No. 20 annealed wire. The serving at the extreme ends is
then cut off, the strands untwisted to the new serving, and the hemp
cores also cut off so as to abut when the open bunches of strands are
brought together, and the opposite strands interlaced regularly with
each other, presenting the appearance as near as can be shown (Fig.
133).

[Illustration: Fig. 133.]

After these are all correctly interlaced, pull the ropes tightly
together, so that the cores abut against one another. Next take {77}
strand No. 1, and as it is being unlaid, follow it up with strand A,
which must be laid into its place tightly until within five feet from
the end. Strand No. 1 is then cut off, leaving it five feet long, same
length as A strand. The remaining stran
