(16) Diagram No. 5—Comparison between different manufacturers, Bessemer and Open-Hearth steel. (17) Diagram No. 6-Comparison between various weights of rail, Bessemer steel, showing graphically results from three years' reports. (18) Diagram No. 7-Comparison between various weights of rail, Open-Hearth steel, showing graphically results from three years' reports. The data, tables 68 to 87, are published herewith on pp. 373-392; also such reports on comparative wear on rails as were found to be of value on pp. 393-400. The information on tables 105 to 172, inclusive, is summarized in tables Nos. 7, 7-A and 7-B. Drawings of the rail sections referred to will be found in Vol. 12, Proceedings, American Railway Engineering Association, Part 2, page 143, et seq. Table No. 1-List of Various Lots of Rail for Which No Failures Were Reported. In this list will be found wide variations in chemistry, different kinds of rail, various sections, and rail of widely different time of service. It is to be noted that much of the rail listed has been in service a short time. Diagram 1. CLASSIFIED RAIL FAILURES. COMPARISON BETWEEN DIFFERENT WEIGHTS OF RAIL- Diagram 2.
