- Editor's Notes
- [from Wadsworth, IL] In my last, mentioned pushing experiment to use sheet iron surfaces of less extent than car roofs. Experimenting on a mail, car tried 4-inch strip of sheet iron under car eaves, then two strips, one under the first, which worked twice as good, though disappointed in that so much sheet iron used. Eight inches wide of sheet iron gave 75 % of roof, but five No. 6 wires gave 90 percent; six No. 6 wires with four No. 9 wires gave 95 %. Experiment shows considerable surface of the roof does nothing but make condenser surface of track active or bring down insulation of the roof. Advantage of the wire might only appear when it's tried on several cars together.
