BUILDINGS 283 



this building is the placing of the pens and out-door yards on 

 the south side of the building. The main windows are placed 

 on the south side also, thus letting the sunlight freely into the 

 pens. The great objection to this plan is the fact that it is 

 not economical of space, because the same passage could be 

 made to serve another row of pens on the opposite side. If 

 desired, the plan could be changed very easily to put a row of 

 pens on each side of the passage by simply making the building 

 about twelve feet wider, or thirty-two feet wide. If this were 

 done, it would be necessary to have a feed room, because the 

 bins in the passage would interfere with the feeding. The 

 passage could be made narrower, however, if the feed bins were 

 removed. 



Beds should be raised several inches above drainage gutter. 



Foundation, floors, and troughs are recommended to be 

 made of cement, but walls of wood, as in Mr. Brethour's 

 piggery. 



The bed floors should be insulated with a tar layer as already 

 described. 



If bedding is plentiful, an overlay of boards or planks 

 need not be placed on the part occupied by the bed. If an 

 overlay is used it should be made so that it can be raised up 

 when desired, to admit of cleaning and disinfection. 



The ceiling should be about eight feet from the floor, and 

 a loft may be put over the whole building with straw chutes 

 leading to each bed. 



The out-door yards should be cemented, otherwise they be- 

 come very filthy. 



Attention is called to the arrangement of the doors (^2) 

 leading from each pen into the passage. The post at the end 

 of the partition is set back from line of passage. In this way, 

 trough room is economized.
