The Yorke is an evolution of the old polka mazourka, and introduces a mazourka movement at pleasure.

The lady slides right foot about twenty inches to the side in second position count 1, bring left to right (change) and almost simultaneously slide right foot to side, count and 2; draw left foot to first position (change), thereby placing the weight on the left foot and raise the right foot from the floor, toe pointed 3. The first three movements are all made to the side without turning—one bar of music.

Hop lightly on the left foot and place the weight on the right foot, sliding it sideways and forward about 6 inches (hop slide), count 1; draw left to right foot in first position (change) count 2; leap from left to right foot, count 3; slide the left foot round to position to commence the sideways movement with that foot, count 1. Repeat, with opposite foot, making the leap in the 4th bar a leap backward as in the waltz. In order to give the mazurka effect, one must strike the heels together, although it is not necessary, and to be graceful in this dance, special attention must be paid to the hop slide.
