BUILDINGS 305 
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 frecly 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 the case of Col- 
lege piggery. 
The bed floors should be insulated with a tar laver 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 (d2) 
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.
