However, this is not the limit towhich treated materials can be used in this type of car. Prac-tically the entire car should be treated, from sub-sills (onsteel underframe cars) to the roof. Where stenciling is neces-sary that can be applied to special boards, or it can be takencare of by the use of metal numerals and signs, the costof which would be a small item in comparison to the savingderived from the use of treated lumber.
