All users of steam boilers will recognize thebenefit of having a supply of almost pure, hot water,which we get from the return condensation. There certainly seems to be a great opportunity fordeveloping this resource. No difficulty ought to beexperienced in making the consumer see the advantage of (ptwdrJ^^OA^^. A ;iiu!

In Menominee, wherethe temperature is low in the winter, no difficulty isfound in sending the steam 1,400 feet satisfactorily, serv-ing 8,100 square feet of radiation, and returning thecondensation at a temperature of 180 degrees to thepower house. This simply shows how practical theplan is. The Government of Turbines Driving Railway Generators. BY MARK A. REPLOGLE.
