Drawing showing 



The roof doors may be liung at the side (see figs. 1 and 15) or at the top 

 (see figs. 10 and 23). The side attacliment allows of a maximum of sunning 

 and convenience, whereas when hung at tlie end considerable shade is possible. 

 Tlie top hinged doors may be arranged so as to be turned back upon tlie op- 

 posite roof, thus enabling the herdsman to attend to the swine without a trouble- 

 some door overhead. 



The arrangement of window sash in the doorways of the roof is a commend- 

 able feature (see figs. 3 and 8) ; especially is this true wlien early pigs are 

 farrowed : It is entirely optional with the builder as to wliether or not 

 the sasli be included. The window sash are best made removable so as to 

 avoid accidental breal^age when not in use. When the houses are moved the 

 stresses may be such as to twist the window frames and crack the glass. The 

 sash should fit snugly to avoid leakage. Standard size sash are preferable as 

 they are more economically purchased than when made to special order. In 

 general the glass sash in roof are of much service in the winter, early spring 

 and late fall. It is quite surprising to the novice to find how much warmer the 

 house is when fitted with glass than when not. One can secure an abundance 

 of sunshine without cooling the house by opening the doors — a necessary pro- 

 cedure when sunshine is wished in houses not equipped with sash. 



C. End Small Doors. — To provide ventilation and furnish means for a con- 

 venient method of observing the swine the small end doors usually placed well 

 toward the comb are a valuable addition ; these, properly located, may be made 

 of glass. 



U. Shade Dooi's. — Swine demand and must have protection from the hot 

 summer sun ; the shade doors solve the problem of furnishing a warm, dry, airy 

 place for rest and comfort. These doors had best be thoroughly re-enforced at 

 the hinges to insure stability and service. 



6. FENDERS. 



For the protection of pigs at farrowing time fendei-s may be provided on the 

 sides and ends of the house. A satisfactory protective fender is made by fasten- 

 ing 2x4-inch pieces flatwise six inches from the floor. If the sides of the house 

 are made into shade doors tlae fenders along these sides should be made de-
