provision of one or two windows in the passage wall in design 1, and in 

 the side walls in design 2, would probably be advantageous. They should 

 be capable of being opened wholly or partially in order to supplement 

 the ventilation in hot weather. A window hinged along its lower edge, 

 and opening inwards, tends to deflect the cold incoming air upwards. 



Ventilation. — In design No. 1, ventilation is provided for by leaving 

 openings along the eaves, i.e. openings between the tops of the side walls 

 and the corrugated iron of the roof. 



In design No. 2, the eaves are similarly open, and in addition the roof 

 is open right along the ridge, this opening being protected by a raised 

 ridge-cap of curved form.

Dry Floors. — The difference between dry and wet floors is the 

 difference between healthy and sickly pigs. In addition to being formed 

 of materials impervious to moisture, the floor should be well and truly 

 laid so that water, etc., cannot collect in pools. The floor should have a 

 good slope towards the sewage outlets. A floor made of permeable materials, 

 such, for example, as an earthen floor, or one of wooden spars, becomes 

 soaked with urine and more or less insanitary and damp. This may con- 

 tribute towards causiDg the pigs to suffer from rheumatism, and parasitic 

 diseases such as worms. It must be remembered that the conditions of 

 pig-life in a pen are not akin to those obtaining in open paddocks. 



Cleanliness. — Pigs repay the trouble expended in keeping their sties 

 clean. Further, pigs will second efforts to keep them clean by themselves 

 developing cleanly habits. 



No feeding-troughs should be tolerated in the sleeping pens ; they
