on the roof and back 

 wall makes it warm 

 and tight. The 

 double-b o a r d i n g 

 around the roosting 

 chamber makes it 

 warmer at night. 

 The cloth curtain 

 windows are hung 

 inside in the winter 

 and outside for 

 awning in the sum- 

 mer. The dust box 

 is placed directly in 

 front of the win- 

 dows with a cellar 



sash in front to give light and warmth and dryness. 



The glass window is made up of a 6 light, 8"xio" sash fastened by 



strips of iron to a second 9 light 8"xio" sash. This is hinged at the side 



to swing back 



against the par- 

 tition wall. Just 



beneath this 



window and di- 

 rectly in front 



of the dust box 



is a 2 light 12" 



X14" cellar sash 



hinged at the 



top to swing out 



and up. This 



makes 12 square 



feet of glass sur- 

 face in each pen 



of 144 square 



feet floor space, 



or I square foot 



of glass to each 



12 square feet 



of floor space.
