The U=Bar Circular Palm House 



Curves are the very key uote of the 

 U-Bar house. The circular palm 

 house is, of course, but the natural 

 development and the most fitting ac- 

 companiment of the U-Bar Curved 

 Eave House. 



To build a circular palm house with 

 other constructions, although not 

 exactly impossible, is decidedly un- 

 desirable, because of the numerous 

 heavy framing members coming 

 closely together at the dome, giv- 

 ing a very cumbersome unpleasing 

 effect. 



Not so with the U-Bar, as the 

 strong light U-Bars entirely support 

 the roof — there being no heavier 

 roof members on the inside than 

 you see on the outside. It is a 

 house of beauty from start to finish. 

 It is the U-Bars that make the U- 

 Bar house — the house with the origi- 

 nal curved eaves. Send for catalog.

 Automatic 

 Circulator 



will force the hot water throughout 

 ijte system and do it without put- 

 ting on a pressure that is liable to 



cause leakage. It does it by mechanically setting the water in motion and keeping it moving 



until the desired heat is just where you want it. 



The Castle Circular has entirely cured the faults of hot-water systems which could not be satisfactorily 

 operated before it was put in. We would like to show you the results of the tests. 

 Our new booklet tells how the circulator works. Write at once to the
