Keep your boiler up on the ground where 

 it is readily accessible for firing and 

 repairs. There's a way to save time and 

 money— trouble ami expense— and still 

 obtain the same drainage facilities. 

 That way is to install the 



Mo%ehettd 



SYSXEM 



The Moiehead System keeps your steam 

 lines dry. hot; increases the circulation 

 and assures a perfect drainage. It feeds 

 the condensate directly to your boilers, 

 thereby maintaining the constant tem- 

 perature so necessary in the greenhouse. 

 And it's so simple, too— so sure. Ask 

 for the complete facts.

of the water in the pipes is based upon 

 a Simple natural law and the best re- 

 sults can be obtained when the system 

 IS arranged in accordance with' the re- 

 quirements of that law. 



The circulation in a hot water system 

 results from the fact that hot water is 

 lighter than coldei water, and when 

 there is a fire in the boiler, the water, 

 being warmed and thus reduced in 

 ■weight, IS pushed out through the flow 

 pipe, which is connected with the top 

 ot the boiler, by the weight of the 

 Heavier cold water in the returns, which 

 are connected with the bottom of the

short and as large as is found feasible, 

 while the returns should be small and 

 of greater length. Of course the exact 

 size of the pipes will be determined by 

 other conditions, such as friction, etc. 

 The rapidity of the circulation will also 

 be influenced by the height above the 

 boiler of both the flow and return pipes. 

 So far as the flow pipes are con- 

 cerned, we believe that it will answer 

 to have one upon each plate for a nar- 

 row house, but as the width of the 

 houses increases we would place a third 

 pipe under the ridge, and in extremely 

 wide houses there should be additional 

 flow pipes under the purlins. These

 way, but may be from one to six feet 

 from the glass, according to the height 

 of the house and the use it is to be 

 put to. By placing one or more of the 

 flow pipes in the middle of the house,
