As a physical education instructor at Newcomb College in Louisiana, she also invented the game "Newcomb ball", now played as a variation of volleyball. Baer had ordered some baskets to play basketball, but the baskets had not yet arrived, so she decided to create a substitute sport. In a letter to the Posse Gymnasium Journal, she described the basic elements of the game, consisting of a court divided at the midpoint, with lines marking where the players could move, and outlining the object of the game, to "make the ball touch the opposite ground, beyond the base—when it counts a point for the side sending the ball". This game would eventually become Newcomb ball, and has many similarities to the game of volleyball. The letter by Baer appeared in the January, 1895 edition of the journal, while the first game of volleyball, invented by William G. Morgan was reported to be first played in February 1895. Her rules of basquette also played a pivotal role in the early development of netball.
