e, then fill up the space
left from _a_ to _c_ by laying in the new strand, and marry the other
end to the short strand _c_. You will then have four splices to finish
off as ordinary long splices (Fig. 118).

(11). +Jury Knot+. The jury knot is useful when a jury mast has to be
rigged, as the loops form a means of attaching the necessary supports
to the mast. The centre _k_ (Fig. 120) is slipped over the masthead,
and the weight brought on the stays tightens it and holds it in its
position on the mast.

{66}

It is formed by three ordinary half-hitches, each placed behind the
other and with the loop of the last laid over the first, as in Fig. 119.

[Illustration: Fig. 119.]

Having done this, keep the hitches together with the right hand, and
with the left take _a_ and dip it under _b_ and pull _c_ through _a_
and _b_. Then, holding the knot with the left hand, place _f_ over
_e_, and pull _d_ between _e_ and _f_. Take _g_ in the teeth and pull
on the parts _g_, _f_, and _a_. The ends _h_ and _z_ may be either
knotted or spliced.

(13). +Sling for a Barrel+.--The following method of slinging a barrel
is adopted when it is desired to hoist it up end on.

[Illustration: Fig. 121.]

Pass the bight _a_ of the rope under the lower end of the barrel and
bring the two parts up, and with them {68} form an overhand knot _b_,
which is opened out so as to fit over the end of the barrel.

The bight _a_ is placed under the cask, and the overhand knot _b_ is
slipped over the head, and the two ends are brought up and knotted as
in Fig. 122.

[Illustration: Fig. 122.]

(14). +Chain Knot+.--An easy and ornamental way of shortening a rope
is that known as the chain knot.

To form it proceed as though you are going to make an ordinary overhand
knot, but instead of working with both ends use the end and a bight as
in Fig. 123.

{69}

This will form the loop _a_, Fig. 123, through which pass a bight of
_b_ and continue in this way until all the slack rope is used up, and
it can be finished off by running the end through the last loop (Fig.
124).

[Illustration: Fig. 123. Fig. 124.]

(15). +Double Chain+.--The Double Chain is a little more intricate
than the chain knot, and is formed by taking a turn round the standing
part and thus forming a loop {70} _c_, through which the end _a_ is
passed, thus forming the loop _b_ (Fig. 125).
