ence. But it should not be placed in the center under the 

 gable, but to the south side, so as not to interfere with 

 the roosts. 



The opening into the yards is placed in the front wall 

 near one end, across the room from the main entrance. 

 It is 12 inches high and 24 inches long. A slide is prefer- 

 able. 



The roosts are made of *^x2-inch stuff running length- 

 wise of the house, preferably in two or three sections, set 

 4 inches apart on cross bars of Ix3-inch. They are 

 hinged with T hinges, the flange of the hinge fastening 

 either to the tongue and groove lining or to the 12-inch 

 board. They are set 8 inches high. Made in this way 

 the roost can be hung against the wall until needed. 



Ventilation is provided by means of two airshafts, lOx 

 24 inches, made absolutely airtight. The inlet shaft, 24 

 inches high, is set to one side of the door, a hole being- 

 cut in the floor to fit it. A slide cover fits over the top, 

 arranged to slide away from the door. This makes it 

 possible to control the amount of air admitted. A screen 

 of 1-inch netting is tacked across the shaft just below the 

 slide. 



The outlet shaft is set in the other end of the building, 

 one edge of it resting against the ridge board. It is fas- 

 tened against the outer wall and hangs 18 inches above 

 the floor, extending through the roof to a height of 2 feet 

 above the peak of the gable. A little gable covering on 

 top keeps out the rain, the sides being left open for the air 

 passage. These side openings are covered with 1-inch 

 mesh wire. (We once found one of our many family cats 

 sleeping warm and comfortable nine feet below the gable
