\textit{I. Kaplansky} [Bull. Am. Math. Soc. 49, 784-785 (1943; Zbl 0060.029)] obtained the number of ways of selecting k balls from n balls arranged in a line without two selected ones being consecutive. This result is generalized to the case of any number of lines when each line can contain any number of balls.
