you come to make the extension. The floor should b« of 

 two thicknesses of boards, with tarred paper between, to 

 keep out dampness. 



One window in the north side is enough. There should 

 "be two in the south side. Throiigh these two the birds fly 

 from house to pen. They may slide up or down, or be hung 

 on hinges, the idea being to provide means for closing them 

 winter nights after the pigeons have taken refuge from the 

 pen in the house. The arrangement easiest operated is to 

 set them in grooves, and attach a rope for closing them from 

 the back of the house. 



Sunlight is as good for pigeons as for all live stock. The 

 windows of the squab house should be large and set as high 

 as possible, especially on the^outh side, where the sun shines 

 in all day. The glass should be kept clean so that the direct 

 rays will fall in the interior of the squab house, dispelling 

 moisture and aiding the process of disinfection which the 

 oxygen in the air performs continually. 



The window or windows in the north side of the squab 

 house should be kept closed most of the year, so as to run 

 no chances on draughts, which are a prolific cause of trouble. 

 In the hot days of summer there is no harm in opening the 

 north windows. The breeder should use common sense in 

 managing the windows so as to keep the air fresh without 

 draughts. 



The nest-boxes are built of boxing and set in a vertical 

 row at the back of the house, forming a wall between which 

 and the north side of the house is a three-foot passageway.
