windows at the right height are a most necessary thing. 

 Hinged roofs or roof sections that can be turned back 

 are also advantageous. If the floor is made of cement, 

 a portion of it may be overlaid with boards for sleeping 

 quarters. The separate pens in the building should open 

 into separate pens outside, but where only a few hogs are 

 kept and the building stands in a pasture field, the differ- 

 ent groups of hogs may learn to come to the same pens 

 to be fed. The styles of this type of house are numerous, 

 but the fundamental requirements are the same. 



Shed-roofed portable house. — This house is best made 

 in detachable sections. The sections may interlock or be 

 hinged or slightly nailed. The roof may slope in one 

 direction or in two. The hinges may be at the highest 

 part of the roof or may stand at right angles to the slope 

 and connect sections. This facilitates raising portions of 

 the roof to admit sunlight and air. If the houses are 

 made without projections they may be placed close to- 

 gether in winter. Farmers' Bulletin 438 of the United 

 States Department of Agriculture gives full directions 

 for the construction of hog houses, and it may be secured 

 without cost upon application to the Secretary. 



The A-shaped portable house. — The A-shaped portable 

 house may be made portable either by nailing all to- 

 gether and moving it on runners from one place to 

 another, or it may be made in sections that interlock but 

 which are easily detachable. The sections may be put on 

 a wagon to be moved. The house made of sections is 

 desirable from another standpoint, since it permits of 

 greater ease in cleaning and can be used to admit a 

 greater amount of sunshine.
