First figure:
A1: Up a double and back. That again.
B1: Set to partner and turn single. That again.
A2: Ones balance back and balance forward; give two hands and slip down below the twos, then turn down and out to face neighbour on the diagonal. Push them up diagonally; lead in to progressed places.
B2: Fall back with neighbour; lead forward. Both couples two-hand turn.
Repeat B1 and B2 until all are back to place.
Second figure:
A1: Partners gipsy L half-way; turn single R. Gipsy R half-way; turn single L.
B1: 1st man jump in to face down, 1st woman jump in to face partner; twos the same. Threes; fours.
Third figure:
A1: Arm R. Arm L.
B1: All four slips L; four R. Four R; four L.
B2+3: Progressive grand chain: Ones give R to partner to start, the others face up and wait to be brought in, all finishing where you started.
This is Cecil Sharp's interpretation. Most recordings only run the first figure until the original fours are at the top.
