One of the myriad minor schottische variations described in M.B. Gilbert's Round Dancing (1890), is notable as the earliest appearance I've noticed of what has become the standard style for the first part of modern folk schottische: three running steps forward in "military position" (as described in my previous post, "À la Militaire") rather than the step-close-step of the nineteenth century dance.
Gilbert attributes the Star Schottische to W.F. Mittman.
The steps below are described for the gentleman; the lady dances on the opposite foot.
First Part (two bars of four beats each)
(take military position, side by side)
1b Three running steps forward, left-right-left, hop on the left foot
1b Repeat, starting with right foot
Second Part (two bars of four beats each)
(close into a normal ballroom hold)
2b Waltz galop (two complete turns)
Gilbert does not describe what the free foot does during the hops in the first part; it could be extended into a raised fourth position forward or simply tucked next to the hopping foot.
At the end of the first part the gentleman must move in front of the lady quickly in order to leap straight backward along the line of dance in the waltz galop. (See my previous description of the waltz galop for how to perform this step.)
