CONSTRUCTION OF HOUSES 175 



is very cold, letting the air come in through these ven- 

 tilators, at the top, without bringing any draughts 

 down upon the birds. Detailed plans of these ven- 

 tilators will be found at the end of this Book. 



The frames of the curtained windows are made of 

 one by four inch boards, with two center supports di- 

 viding the window frame into three foot sections. 

 These frames are covered with medium weight cotton 

 duck, from which the dust must be brushed at regular 

 intervals to permit the air to circulate through them 

 freely. 



Outside of the Office, Brooder House, Work Shop, 

 Stable and the Resident Quarters, no glass is used in 

 any of the buildings, with the exception of one small 

 pane in the door of each Laying House, through which 

 a view of the interior may be had. 



A hood, extending out eight inches, is built over the 

 windows and ventilators, the whole length of the 

 buildings. This prevents the rain from southerly 

 storms beating into the Houses. 



The windows are hung on hinges, and open inward 

 from the top, and are fastened to the ceiling with 

 wooden buttons. 



The front of all of the window openings, on the 

 outside, is covered with one inch mesh wire netting, to 

 prevent the birds from flying out, and also to prevent 

 sparrows and other birds from flying in to consume the 

 grain provided for the fowls.
