radiation by the foregoing formulas 

 may seem a difficult task, but it is 

 really quite simple. Thus, in a living 

 room 12x14 and nine feet high, with 

 one end and side exposed — that is, they 

 are outside walls — and with two win- 

 dows, each 3x6 feet, there will be 

 thirty-six square feet of glass, the ex- 

 posed wall surface will amount to 234 

 square feet, and the cubic contents 

 of the room is 1,512 feet. Then we 

 shall need for radiation thirty-six square 

 feet, the area of glass; plus twenty- 

 three feet, which is one-tenth of the 

 exposed wall; plus fifteen feet, which

over a steam pump for steam line drainage and boiler 

 feeding. 



Substituted for pumps, the Morehead System will 

 keep all steam pipes clear of condensation and return 

 it to the boiler as pure, hot feed water quicker and 

 on 90% less steam than a steam pump will do it. 



The installation expense is small— the results great. 

 It matters not whether your institution is large or 

 small, the Morehead System will save sufficient to 

 pay for itself in a a few months' time. Letters in our 

 files prove this. Let us tell you about it.
