A DOUBLE DIAMOND KNOT. (15.) Make a single diamond, as above, without laying the ends up. Follow the lead of the single knot through two single bights, the ends coming out at the top of the knot. Lead the last strand through two double bights. Haul taut, and lay the ends up. A SPRITSAIL SHEET KNOT. (16.) Unlay two ends of a rope, and place the two parts together. Make a bight with one strand. Wall the six strands together, like a single walling made with three strands; putting the second over the first, and the third over the second, and so on, the sixth being passed over the fifth and through the bight of the first. Then haul taut. It may be _crowned_ by taking two strands and laying them over the top of the knot, and passing the other strands alternately over and under those two, hauling them taut. It may be _double walled_ by next passing the strands under the wallings on the left of them, and through the small bights, when the ends will come up for the second crowning; which is done by following the lead of the single crowning, and pushing the ends through the single walling, as with three strands, before described. This is often used for a _stopper knot_. A STOPPER KNOT.--Single wall and double wall, without crowning, and stop the ends together. A SHROUD KNOT.--Unlay the ends of two ropes, and place the strands in one another, as for a short splice. Single wall the strands of one rope round the standing part of the other, against the lay. Open the ends, taper, marl, and serve them. A FRENCH SHROUD KNOT.--Place the ends of two ropes as before. Lay the ends of one rope back upon their own part, and single wall the other three strands round the bights of the first three and the standing part. Taper the ends, as before. A BUOY-ROPE KNOT.--Unlay the strands of a cable-laid rope, and also the small strands of each large strand. Lay the large ones again as before, leaving the small ones out. Single and double wall the small strands (as for a stopper knot) round the rope, worm them along the divisions, and stop their ends with spunyarn. A TURKS-HEAD. (17.) This is worked upon a rope with a piece of small line. Take a clove-hitch slack with the line round the rope. Then take one of the bights formed by the clove-hitch and put it over the other. Pass the end under, and up through the bight which is underneath. Then cross the bights again, and put the end round again, under, and up through the bight which is underneath. After this, follow the lead, and it will make a turban, of three parts to each cross. TWO HALF-HITCHES. (18.) Pass the end of a rope round the standing part and bring it up through the bight. This is a half-hitch. Take it round again in the same manner for two half-hitches.
