(2). A Figure of Eight Knot.—Back e round behind a, bring over part z and dip down through bight b and haul taut (Fig. 10).

Fig. 10.

(3). A Simple Clinch is formed by closing up the initial loop to form a small ring and securing by a seizing—a small lashing at d (Fig. 11).

Fig. 11

One of the preceding knots is generally put in the end of running gear to prevent it from coming unrove from the fair-leads or blocks.

(4). A Running or Inside Clinch is the foregoing, formed by the end of a rope on its own standing part, and is often used for securing buntlines to the foot of a sail (Fig. 12).

Fig. 12.

(5.) An Outside Clinch, as may be inferred from its name, is formed in a similar manner, but the end c is brought round on top, that is, away from the bight (Fig. 13). It is used in cases where it is essential that the end should not be in a position to jam, but always ready for slipping at a moment's notice, as in securing cable ends, etc.

Fig. 13.

(6). A Buntline Hitch (an alternative method of securing buntlines to a sail) is commenced as in making an outside clinch, but instead of putting on a seizing, take a longer end c, pass it over y, bring up through bight b, and tuck the end again over part y and through the last loop formed, so that the end c lies close to the commencement of part z (Fig. 14).

Fig. 14.

(7). A Bowline.—Reverting to our original loop (Fig. 8), first taking part z in the right hand with y in the left, throw a loop over c, the end, as in Fig. 15.

Fig. 15.

Secondly, lead c round behind part a and pass it down through the last made loop, as indicated by the dotted line, and haul taut as in Fig. 16.

Fig. 16.

(8). A Running Bowline.—Form a loop with a long end c lying underneath the standing part a (Fig. 17).

Fig. 17.

Now bring end c over part y and with it form the bowline knot on part z just as in the previous case we formed it on its own part, when it will appear as in Fig. 18. It is used whenever a running noose is required.

Fig. 18.

(9). The formation of a half hitch (Fig. 19), and two half hitches (Fig. 20) is sufficiently indicated by those diagrams.

Fig. 19.

Fig. 20.

The commonest method of making a rope's end fast to a bollard, etc., is by taking a round turn and two half hitches, and stopping the end back for further security (Fig. 21).

Fig. 21.

(10). A Clove Hitch is really a jamming form of two half hitches, and is principally used when a small rope has to be secured to a larger one and the end still kept free to pass along for further purposes, as in securing ratlines to the shrouds. Its formation is shown in three successive stages (Figs. 22, 23, 24).

Fig. 22. Fig. 23. Fig. 24.

(11). A Rolling Hitch is commenced and finished like a clove hitch, but as will be seen from the three diagrams (Figs. 25, 26, 27) illustrating its construction, there is an intermediate round turn between the first and last hitches. It is principally used for securing the tail of a handy billy or snatch block to a larger rope, or when hanging off a rope with a stopper.

Fig. 25. Fig. 26. Fig. 27.

Note that the round turn in (Fig. 26) is taken round both the standing part a and the larger rope. The great value of this hitch is its non-liability to slip in the direction B (Fig. 27). If, however, owing to an extremely severe strain or other causes the hitch is inclined to slip, the end e should be backed round part d of the first rope, that is, twisted around it in long lays in the opposite direction to that in which the hitch was formed, and the end secured by a stop (Fig. 28).

Fig. 28.

(12). A Timber Hitch is a useful way of securing a rope quickly to a plank, but when there is to be a long and continuous strain, or when it is required to keep the end of a piece of timber pointed steadily in one direction, it should be supplemented with a half hitch (Figs. 29, 30).

The timber hitch itself consists simply of a
