ventilation and as doors. When used as doors, the wire screen 

 must be put on a frame so that it also may be opened, as represented in 

 Fig. 66. 



In addition to the glass there are two muslin curtains each 3 feet high 

 and 5 feet long, making I square foot of cloth surface to every 26.6 

 square foot of floor. The cloth windows are hinged at the top to swing 

 in and fasten open as shown in Fig. 64, it being customary to keep them 

 open the greater part of the day. The opening is well above the floor.

This prevents a draft blowing directly on the fowls. With this type of 

 open-front house it is of prime importance to construct the remaining 

 sides of the pen tight, thus preventing any possible draft. These con- 

 ditions allow the least possible draft, but at the same time provide an 

 abundance of pure, fresh air so vital to the comfort and health of the 

 fowls. 



A house of this width is not usually covered with a shed roof, which 

 would give it a somewhat ungainly appearance, but rather with a com- 

 bination or a half-monitor roof. The combination roof especially gives 

 the building a symmetrical appearance not to be obtained with the shed 

 nor even with the low gable roof.
