24.—THE COLUMNS.
The conductor leads off with a tour de valse, and leaves his lady in the middle of the room. He takes a gentleman, whom he places back to back with his partner; he then brings another lady, whom he places facing the gentleman, and in the same manner with the others, until a column of five or six couples is formed, which must terminate with a lady, the leader himself standing back to back with the last lady. At a signal by leader, all turn about and waltz with his or her vis-à-vis. Two or three lines can be formed by starting two or three couples. The columns can also be used as a final figure.
