The Costly Cost 

 Of Robbing Peter To Pay Paul 



Speaking of robberies, let's first speak of 

 car gears. 



Cars have gears to give a range of speeds aud 

 power. 



You caa have your highest speed with your 

 hiijhest gear, but you also have the lowest 

 power. 



Low gear gives the greatest power but the 

 least speed. 



You simply can't have both the greatest 

 speed and greatest power at one and the 

 same time. 



With greenhouse construction, it's exactly 

 the same way. 



You can have some things, if you have others. 



Or you can have others, if you have some. 



For example, take columns. 



If you take out columns, you must put in 

 trusses, tliat will do what the columns did. 



You can't rob Peter to pay Paul. 



It takes just so much supporting to support 

 any roof. 



Reduce the si/.e of those supports and some 

 fine morning you will look out the window 

 and find your house lying down for a nice 

 long nap. 



Putting columns in a house is so simple in 

 its principle that you can't go very far wrong. 



But when it comes lo trussing a house you 

 get into stresses and strains. 

 Which iu turn gets you into engineering com- 

 plications, with figures, and figures, and more 

 figures. 



Our engineer figured out the weights and 

 strains, etc., which determined the si/e and 

 design of the various members. 



We proved up the figures by building the 

 trusses in the factory and testing them. 



Every truss we put in a house has a surplus 

 of strength for emergencies, such as a heavy 

 snow, or a twister of a wind. 



That's why you have never heard of one of 

 our big houses gomgdown. 



If these stand-up-facts interest you, and you 

 want more, we have a lot more to give you.
