Charcoal ironcarries considerably more impurities thansoft open hearth steel, and these impuri-ties form a self-fluxing mixture whichfacilitates welding. Railroad specifica-tions have been so tightly drawn on com-position in some cases as to work againstthe production of a good quality of steel■ locomotive b es by calling for unnecessarily low phosphorus and is now very good reason to thinkthat a mistake has been made in thisdirection and that the general weldingquality of the steel would be much im-. RAILWAV CLUB OF PITTSBURGH ON A VISIT TO THE ELWOOD CITY PLANT OF THE NATIONAL TUBE COMPANY affliction doubly severe for those whosurvived him. Manufacture of Steel Tubes. The April meeting of the PittsburghRailway Club was made notable by a visitto the Elwood City plant of the NationalTube Company, the members and a largenumber of friends having been guests ofthat company. The visit was greatly en-joyed by the visitors, so much interest wasmanifested in the various operations con-nected with the manufacture of seamlesssteel tubes. This is the kind of objectlesson that helps to broaden the minds ofrailroad men concerning articles largelyused in their business. If more of such•visits could be made there would be service and open hearth steel is now thefavorite material. Seamless and lapwelded steel tubes are now made from thesame grade of soft basic open hearthsteel. Tubes ought to
