st four bars by No. 5. No. 3 must follow No. 1
in the other circle of the 8, and No. 5 must get back to his station
along the double curve travelled in the first four bars by No. 1. Thus:

[Illustration: Fig. 6.]

[Illustration: Fig. 7.]

The Chain is danced by Nos. 2, 4, and 6 precisely in the same way: No. 2
is always leader; always turns _outward_; and Nos. 4 and 6 always follow
No. 2 on the lines of the double curve, or figure 8. No. 6, as No. 5,
passes between Nos. 2 and 4, in chaining.

Occasionally, as for instance in "Country Gardens," the term "Half-chain"
will be found. This means that the movement shown in Fig. 4 is executed
to four bars of music; another movement follows; then "Half-chain" again,
bringing numbers back to original stations.

If, as very often occurs, the Chain follows a movement executed in Front
formation, the dancers simply turn and follow one another as shown in
diagrams, when the Chain music begins.

This is called in the Notation--Chain.

CROSS-OVER.

This movement is executed in Front formation, to eight bars of music, as
follows:

In the first two bars each dancer crosses over and takes the place of his
partner, setting the pairs back to back, thus:

[Illustration: Fig. 1.]

[Illustration: Fig. 2.]

In crossing and re-crossing, _invariably_, each must keep his partner to
the right, that is, the right shoulder of each passes by the right
shoulder of each partner.

In bars 3 and 4 (keeping up the step all the time) all come to the
right-about, that is, face inward again, by turning to the rightward
(maintaining position all the time), thus:

[Illustration: Fig. 3.]

[Illustration: Fig. 4.]

In bars 5 and 6 all cross over again, right shoulder to right shoulder,
bringing the side back to back and in original stations.

In bars 7 and 8 all make a full turn to the right (as in Fig. 3) bringing
the side again to Front.

As there are two bars to turn in after crossing over, and again after
re-crossing, the dancer must, of course, turn slowly and evenly, so that
the turn is completed just in time for the jump in bars 4 and 8.

This is called in the Notation--Cross-over.

BACK-TO-BACK.

As with the Cross-over, this movement is completed in eight bars.

In the first four bars partners advance, right shoulder to right
shoulder, but not touching, pass one another, move to the right, re-pass
partners (left shoulder to left shoulder), and retire to position, moving
