A correspondent of the Chicago Tribune thinks that the moral of the Ash tabula accident is - iron cars. " Let the cars," he says, " be built entirely of iron, like many of the baggage and express cars now in use on the New York Central railroad. Let them be heated by steam from the engiae, or by a furnace underneath the car, so arranged that by no meaus can flre get into the body of the car. Use less glass snrface for windows. Many persons lost liieir lives by being pierced by the shaippointed fragments of glass left in the frames in whïch they are set. Have tho doors open ontward, that they may not be bloöked and fastened by anything that might face against them. Wo havo iron steaix. ships and iron buildings, why not iron railroad cars ?"
