for supporting this a row of posts made of gas pipe, varying in size from 

 one inch to two inches, should be used. Our houses measured ten feet in 

 height inside and we used 1^ inch posts. These also served as supports 

 for the main heating pipes. 



When the sash bars are more than eight feet in length they should be 

 strengthened by some form of purlins and purlin posts. For the purlins 

 the use of wood alone is not desirable, but a thin strip of wood with a 

 back of one-inch angle iron will be both neat and strong. 



We made use of one-inch iron pipe fastened to the middle of the sash- 

 bars, and sujDported by another pipe of the same size running to the center 

 posts. These are neat, strong, inexpensive, and have the added qualities of 

 shutting off little light and of not rotting out. ( Figs. 4 and 5. )
