As far as thewriter knows, the connection of this big flue with the tubesheets has not given any trouble due to leakage, but Schmidtabandoned this design merely to avoid the danger which. FIG. 1 may develop on account of it. A greater number of loco-motives of the Belgian State Railway is equipped with thissuperheater and according to the statement of MonsieurFlamme, general superintendent of motive power, the sav-ing of coal amounts to over 25 per cent. Next to the saving in coal, by the use of superheatedsteam, comes the increase in the capacity of the boiler andthe saving of feed water, which averages more than 30 percent. This feature is very important because in many in-stances a water station with exceptionally bad water can beabandoned or used for emergency. Boiler washings will bereduced and cost of water supply decreased proportionally. According to the statistics of railways for 1904, compiledby the Interstate Commerce Commission, the repairs andrenewals of locomotives amounted to $115,000,000, whilefor engine and roundhouse men about $130,450,000 wasexpended.
