(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 c, through which the end a is passed, thus forming the loop b (Fig. 125).
The end a is brought back and dipped down through b and this is continued as long as required, finishing off by running the end through the last bight and hauling it taut (Fig. 126).
(16). Twist Or Plait Knot.—Another method of shortening a small handy rope is known as the twist or plait knot.
