revelation of the heart of a people simple, sympathetic, unrestrainedly romantic, violently impulsive. Each represents an exciting diversity of ammunition, fired in one rousing volley; an expression to which one may become accustomed, but which always remains unfamiliar, and which always produces an intoxicating shock. The abrupt changes of movement from slow to fast, from furious speed to a dead standstill; the recurrent crescendo from short, close movement to broad sweeps, open jeté turns, and the lowest of “dips”; the diverse effects gained by play of rhythm—such effects are indescribable in word or picture. Fortunately, however, characteristic poses are within the range of the snapshot; so also, to an extent, is the expression of human moods—if portrayed by rare pantomimic ability.

Possession of such ability, backed by the unfettered imagination of the Tartar and accompanied by superlative artistry, describes Miss Lydia Lopoukowa. To her great kindness this book is indebted for the accompanying photographs representing characteristic poses and moods of northern Slavonic dancing. Taken from the work of such an artist, the pictures represent an idealisation, or perfection, of their subjects. They show movements of the dances themselves, in their spirit, without the usual limitations imposed by physique. The clean-cut definition of pose; the co-ordination of pose and features in all the expressions of allurement, appeal, petulance, esctasy—these represent a standard at which the merely mortal dancer aims, but a conjunction of conditions that one may hope to see accomplished few times in the course of one life.

Yet, as noted before, the dances are so composed that, performed with a degree of skill not uncommon in their native land, they are rich and surprising. In steps, the Russian, Austrian and Polish group have most of their material in common: naturally, since they are united by ties of race. The salient point by which each dance is distinguished, in the eye of the spectator, is one big step.

The Czardás employs a long glided step that is all its own. The active foot is started well to the rear, and glided forward; the glide is accompanied by a very low plié of the supporting knee; as the active foot comes into advanced position, the dancer sharply straightens up, rises to the ball of the supporting foot, and continues the advancing foot forward and upward in a rapid kick. The masculine version drops the body lower, and kicks higher, than the feminine; but even the latter’s change of elevation remains fixed in the memory.

In the Obertass, the man goes into the low stooping position, in connection with executing a very individual rond de jambe. At the moment, he is face to face with his partner, his hands on the sides of her waist, her hands on his shoulders; after a swift step-turn in the usual direction, he takes a long step backward (she forward), and, keeping his right leg extended before him, stoops until he is squatting on his left heel; the right leg, held straight, is swept rapidly around to the rear; meanwhile the couple continues to turn. The man’s momentum turns him until he faces in the same direction with his partner. He springs up on her right side, and goes with her into a short, fast polka-step. During the turn, the woman keeps hold of the man to prevent centrifugal force from flinging him into space.

In the Mazurka (not the ballroom version) the same
