for a sow and her litter, or as a shelter for two or three sows. 



The description is taken from Bulletin 153 of the Wisconsin 



Experiment Station. The pen is constructed by nailing inch 



boards on six joists, each 2 by 4 inches, and 7 feet 8 inches 



long, for the floor. Beneath the joists are nailed three stringers, 



each 2 by 6 inches, and 8 feet long, which serve as runners 



for moving the house. Next, a plate piece 2 by 8 inches, 



and 9 feet 4r inches long, is spiked to the ends of the joists, 



having the bottom of the 2" by 8" even with the bottom 



of the joists, which will allow it to project 3 inches above the 



floor. It will also extend out Y inches at each end. This 



2" by 8" forms a plate to which the rafters and roof boards 



are nailed. The 7-inch extensions of the plate at the ends 



support the cornice, and protect the lower comers of the roof, 



which otherwise would be easily split off. The 2" by 8" planks, 



besides strengthening the house, raise the rafters and the roof 



boards nailed to them, at least three inches off the floor, and 



thereby increase the floor space and capacity of the house. 



The following lumber is necessary to construct the A-shaped 



pen illustrated here : 



Fine pieces, 1" X 12" X 16' and 11 0. G. battens 16' long for roof. 



Five pieces 1" X 12" X 14' for ends. 



One piece 2" X 4" X 10' for ridge. 



Two pieces 2" X 8" X 10' for plates. 



Seven pieces 2" X 4" X 16' for rafters, and braces in frame. 



Three pieces 2" X 6" X 8' for runners. 



Pour pieces, 1" X 12" X 16' for flooring. 



If the house is to be used in cold weather, a door will be 

 necessary, which may be hung on hinges or made to slide up 

 out of the way. The doorway is shown in the drawing, two 

 feet by two feet six inches. In the case of very large sows, it 

 would be better to make the door three feet high. 



The dotted lines in the drawings indicate the scantlings 

 which constitute the framework of the pen.
