Most important is to have a winter pen house where the first filters can be safely farrOWed in February and early March; and then repeat in the fall.
 The design illustrated is the special American Builder type of modified saw-tooth as designed for roof winS dows. These are placed in such way that the direct rays of the sun shine di- reetly into the nests at Throwing time.
 There are several different makes of these special roof windows-all con structed on much the same principle. They have galvanized sheet iron frames which carry their own flashing, and so can be easily set in place on the roof and made water tight.
 For the sake of sanitation saving of feed and the lessening of labor the per floors and also the outside run yard are constructed of concrete.
 In building q hog house it is neces- sary to consider convenience in getting the hogs ill and out, to provide means for loading them into wagons and a place for heating water and for feed cooking and mixing. When built on sloping ground as Is generally the case this plan offers an opportunity to back the wagon up to the rear door for loading and room in the front end away from the pens is arranged for feed room.
 Provision is made for moving hogs frem one pen to another by having cleats in the alley for holding sliding doors.
 Hogs thrive better when animals of the same size are penned together. Some grow faster than others and it is sometimes desirable to select out one or two from certain pens. That is the time when the alley door will be appre- ciated. Another good thing about this hog house is the swinging front of the pens which swings back over the trough and prevents interference when putting in the feed. The partitions next to the feed room run to the ceil ing but the partitions between the pens are only four feet high.
 This hog house will accommodate about 100 hogs by housing from six to eight in pen, which is thick enough; {; If more are penned together they pile UP and smother each other.
 This hog house contains Is indi- yidual pens. with an alley through the center.
 II is 24 feet wide and 57 feet long, with two main entrance doors at the ends of the feeding alley. Each pen On the south side of the building has an outside door to connect the inside stalls with the outside exercising pens
 The foundation is of concrete. and there is a solid concrete floor the full size of the house. This floor iS care fully made and given smooth water proof finish, so il may be kept clean with the least possible expenditure of labor. The concrete wall extends up ] IS inches above the grade line to pre- vent the possibility of draft of cold air on the nests. All doors are care l fully fitted to shut tight in the winter time.
 Each pen has a concrete feeding trough and swinging gate opening in- l to the center alley. These gates are very convenient when transferring from one pen to another. They are 1 also handy at breeding time, because the presence of the attendant inside of the pens is frequently necessary.
 The construction above the concrete consists of studding. outside boarding, strong building paper and drop siding. So far as the sides are concerned. it
