cover this with about one foot of straw so that the air can readily 

 circulate from tne pen up through the straw. To make this 

 complete, cut a small door or window in each gable end and then 

 have these windows open except during the severest storms. 

 This will be found the most satisfactory method of remodeling 

 many of the old gable roof houses. 



Semi-Monitor itoof. This type of roof shown in Figure 6 4 

 is often used and is practical. Many of the old narrow shed 

 roof houses are remodeled by building an addition on the south 

 side forming a roof of this type. This type of roof is utilized 

 to better advantage in a small stationary house than in a long 

 house. It is unsuitable for a continuous house as the south side 

 is built so low that it is practically impossible to clean out the 

 litter without carrying it to the end of the building. It is pos- 

 sible in this type of roof to reduce the air space and secure sun- 

 shine in the very back of the pen, and makes a very practical 

 small poultry house. Many times the south side needs only 

 to be covered with wire, and in mild localities it is to be recom- 

 mended for the open front type. The south side being low, 

 storms do not readily enter, but this type will not be found 

 suitable in windy localities. 



Monitor Type. The Monitor roof shown in Figure 6 5 is 

 excellent for warm climates. It is not, however, satisfactory in 

 cold climates as the house contains too large an air space and is 

 too expensive to build. 



Slanting Front Type. The slanting front type shown in 

 Figure 6 : 6 is found on some of the old poultry houses but has 

 not proven satisfactory. 



As a general rule for the farm, it is better to use one of the 

 first four types discussed, and just which type one uses should 

 depend to quite an extent upon individual taste, but the style 

 of the roof and the width of the house should always be deter- 

 mined upon before starting to build. 



"A" Type. The "A" type of roof shown in Figure 67 

 may be used advantageously on the small colony house and in 

 the large poultry house where an alleyway is desired in the 

 center with pens on either side. In the small colony house the 

 windows are placed in the ends; in the long continuous house 

 the windows would be built in the roof and care must be taken 

 to make them rain proof. To guard against breakage, a wide 

 screen should be placed over them on the inside. They should
