When you can buy a genuine greenhouse boiler made from top to bottom es- 

 pecially for greenhouse work — then why under heaven don't you buy it? 

 What's the use of trying to make yourself believe that a boiler originally de- 

 signed for residence heating can possibly give the height of economy for green- 

 house work ? You know the conditions are absolutely different. The residence 

 boilers were designed to do heating with small pijjes in a vertical position where 

 rapid circulation is an easy thing. 



Now put such a boiler to work in a 

 greenhouse with horizontal pipmg and 

 with a large mass of water to move 

 and you have an entirely different 

 proposition — the residence boiler has 

 not the power to do it economically 



without forcing. And forcing a boiler 

 means not only shortening its life, but 

 you also drive a surprising amount of 

 heat out the chimney. Heat that 

 costs you hard dollars. 



So go careful! 



Make sure you are buying a 

 Cast Iron Sectional Greenhouse 

 Boiler made especially for green- 

 house work. 



The' Bumham" is that kind.
