HOUSING AND HYGIENE 



267 



Graham' reports a five years' test of the four houses shown 

 in Fig. 143. These houses all had the same floor space, 

 being 12 x 24 feet, and divided into two pens 12 feet square. 

 They were stocked with birds of as near the same strains of 

 White Wyandottes and Buff Orpingtons as it was possible to 

 secure.

Four types of houses tested at Ontario Agricultural College. 



" House No. 1 is made of matched boards, which are dressed 

 on one side. The front and ends of the house are single 

 ply. The ba,ck is sheeted on the inside, building paper being 

 used under the boards so as to make the wall tight and free 

 from drafts. The windows in the house slide back and forth 

 so that the ventilation can be adjusted to the weather 

 conditions. The roosting quarters in this house have curtains 

 which can be dropped on very cold nights. 



" The second house is what is known as the 'Maine Station' 

 house. This house is practically open to the weather on the 

 front or south side. There are canvas curtains which can 

 be dropped as a protection against wind and snow on stormy 

 days and may be rolled up on the fair days. The ends of the 

 house are single-ply matched lumber. The back wall of the 

 house is of matched lumber and lined with paper, and is 

 sheeted again (?n the inside. This is done in order to make 

 a warrn roosting coop, which is protected at night in front by 

 canvas curtains.
