10 and 11. Shell in two views used in No. 65, showing the disposition
of it at the throat. This joining is advantageous, as it does not
strain the cords, and it prevents them from cutting each other; so
that the rings pass one into the other and are joined outside the
intermediate shell.
12. Interlacing in two directions.
13. Mode of finishing the end by several turns of the twine continued
over the cable.
14. Interlacing commenced, in one direction.
15. Interlacing finished, the ends being worked under the strands, as
in a splice.
16. Pigtail commenced.
17. Interlacing fastened.
18. Pigtail with the strands taut.
19. Dead eye, shown in two views.
20. Pigtail finished. We pass the ends of the strands, one under the
other, in the same way as if we were making a pudding splice: thus
bringing it in a line with the rope, to which it is seized fast, and
the ends cut off.
21. Scull pigtail; instead of holding the ends by a tie, we interlace
them again, as in No. 16, the one under the other.
22. Pigtail, or "lark's nest." We make this to the "pennant" of a
cable, which has several strands, by taking the requisite number of
turns over the pudding, in such a manner that the strands shall lay
under each other. This "pigtail" forms a knot at the end of the
rope. It thus draws together two ropes, as shown in No. 32, forming a
"shroud" knot. In these two pigtails, the strands are crossed before
finishing the ends, so that the button, a, is made with the strands,
a, and b, with those of the rope, b.
23. Slip clinch to sailors' knot.
24. Slip clinch, secured.
25. Ordinary knot upon a double rope.
26. Bowline knot for a man to sit in at his work.
27. Called a "short splice," as it is not of great length, and
besides, can be made quickly.
30. Long splice. This extends from a to b. We unlay the strands of
each of the ropes we intend to join, for about half the length that
the splice will be, putting each strand of the one between two strands
of the other.
31. Simple fastening on a rope.
32. A "shroud" knot.
33. The ends of the rope are prepared for making the splice (No.
29) in the same manner as for the "shroud" knot in No. 32. When the
strands are untwisted, we put the ends of two cords together as close
as possible, and place the ends of the one between the strands of the
other, above and below alternately, so as to interlace them as in No.
29. This splice is not, however, very strong, and is only used when
there is not time to make a long splice, which is much the best.
34 and 35. Marline spikes. Tools made of wood or iron, used to open
out a rope to pass the strands of another through it.
36. Shows strands arranged as described in No. 30.
37. Fastening when a lever is used, and is employed when hauling upon
large ropes, where the strength of several men are necessary.
