**The ball was adjusted at the right height, and, taking up a bat that was electrically wired, Ruth was told to get into position and to swing his bat exactly as if striking the ball for a home run, to make the end of it touch one of the transverse wires on the plate behind him, then swing it through its natural arc and hit the ball lightly. The bat, weighing fifty-four ounces (exactly the weight of the bats Ruth uses on the diamond), was swung as directed, touched the ball, and the secret of his power -- or, rather, the amount of force with which the strikes the ball -- was calculated. At least, the basis of the problem was secured: The bat, weighing fifty-four ounces, swinging at a rate of 110 feet a second, hits a ball travelling at the rate of, say, sixty feet a second, the ball weighing four and a quarter ounces, and striking the bat at a point four inches from the end. How far will it travel? There are other elements [p. 21] entering into the problem, such as the resilience of the ball, the "English" placed on it by the pitcher's hand, and a few minor details. But the answer, as proved by the measurements, is somewhere between 450 and 500 feet. This problem cannot be worked down to exact figures because of the unknown quantities.
