The factthat the increase in price is more than offset by the re-duction in the number of joints accounts for the generaladoption of this length. CHEMICAL COMPOSITION OF RAILSOut of a total of thirty representative street railwaycompanies in the United States, it is gratifying to notethat about one-third are taking up the question of chemi-cal composition of rail in purchases. A number are usingeither Class A or Class B of the American Electric Rail-way Engineering Associations recommended specifications,and several companies have purchased rails treated withvarious percentages of titanium alloy. The United Rail-ways Company of St. Louis, Mo., has adopted a speci-fication consisting of: carbon, to ; phosphorus,. Concrete Mixer Placing Paving Foundation, Memphis Street Railway changed from standard unless it is in an unpaved street,but the weight of the rail is reduced, it usually being a7-in., 70-lb. or a 9-in., 106-lb. grooved girder. Practically all street railway companies making rail pur-chases specify 60-ft. to 62-ft. lengths. Thus they reducethe number of joints 50 per cent at a slight increase in thepurchase price and in the cost of handling. At the presenttime rail manufacturers are quoting $39 per ton carsChicago for girder rail in 60-ft. lengths and $37 per Chicago for girder rail in 33-ft. lengths, manu-factured by the open-hearth process. Standard manufactured by the open-hearth process arequoted at $30 per ton cars Chicago for and $32 per ton cars Chicago for To obtain the minimum price per ton, a minimumof 250 tons of girder rail or 500 tons of rail must be or
