N. McD. Crawford (by letter): I desire to explain more fully the term "A" in the efficiency formula given in my paper. The definition of the term, as given, may be misleading; its value is obtained by multiplying the average watt-hours per ton-mile by tons weight of car, and this result by the cost of power per watt-hour at the switchboard.
