Figs. 19 and 20 show a Wall Knot. Unlay the end of a rope and with the strand A in Fig. 19 form a bight, hold it down at the side B, pass the end of the next strand C, round A, the end of strand D round C and through the bight of A. Haul taut and the knot is made as in Fig. 20. This can be crowned by taking strand in Fig. 21 and laying it over the top of the knot. Then lay B over A, and C over B and through the bight of A and haul taut. Fig. 22 shows a double wall and double crown, which is made by letting the ends follow their own parts round until all the parts appear double, first walling and then crowning.
Matthew Walker Knot—Made by unlaying the end of a rope and taking the end A round the rope and through its own bight, the strand B underneath through the bight of A, and the strand C underneath through the bights of strands A and B, and hauling all the strands taut. This knot is used principally for the ends of lanyards. In making these knots a whipping of sailmaker's twine should be put round the rope where the knot is to be when formed.
This illustration shows the process of worming a rope, which consists of winding spunyarn of suitable size into the space between the strands with the lay of the rope, so as to make the rope smooth for parcelling. This must be done with the rope on the stretch. A shows the spunyarn.
This illustration shows the process of parcelling and serving. After the worming is finished wrap narrow strips of canvas—tarred, if the rope is of hemp, and painted if it is of wire—round the rope with the lay, secure the parcelling to the rope by marling it with twine, the rope can then be served against the lay. Lay the serving mallet B with its groove on the rope. Take a turn with the spunyarn round the rope and head of the mallet, round the side next you, and two turns on the other side and twist it round the handle. Get an assistant to pass the ball A round the rope while you heave round the mallet. The last half-dozen turns of the service must have the end of the spunyarn put through them and hauled taut to secure it.
