and the incubators have to be adjusted to the changes as they 

 occur. At present the room contains two 600 egg size "Mon- 

 arch" incubators, one 132 egg size "Peep O'Day," and one 

 400 egg size "Excelsior" incubators. 



BREEDING HOUSE. 



The ground upon which the poultry buildings are located 

 slopes somewhat to the south and east, and gives good surface 

 drainage. The soil is reddish loam, inclining quite strongly to 

 clay, and is rather heavy for yards and walks in wet weather. 



The breeding house is 16 feet wide and 150 feet long. It 

 faces the south and conforms nearly to the land surface, the 

 east end being 5 feet lower than the west end. The sills 

 are of 4x6 inch hemlock, placed flat upon a rough stone wall 

 which rests upon the ground surface, and varies from 1 to 

 2 feet in height. The earth is graded up to within 6 inches 

 of the sills on the outside. 



The floor timbers are 2x8 inch plank, placed 2^ feet 

 apart, and are halved on to the sills. The studs for the 

 back wall are 2x4 stuff, 5 feet 8 inches long, and rest on the 

 sills. The front studs are 10 feet 6 inches long. "All studs are 

 set 3 feet apart. The plates and rafters are of 2x4 stuff. 

 The rafters are 3 feet apart. Each 10 feet in length of the 

 front of the building has one 12 light window of 10x12 glass. 

 The top of this window comes within one foot of the plate. 

 Directly underneath these windows, and 6 inches above the 

 floor, are other 3 light windows of i0xi2 glass. There is 

 a door in each end 3x6 feet. The building is boarded and 

 papered all over outside, and the ends and back wall are 

 shingled, while the front wall is ceiled with matched boards. 



The floor is 2 thicknesses of hemlock boards. The entire 

 inside — Avails and roof— is papered on studs and rafters with 

 black Neponset sheathing paper. All edges of the paper lap 

 on studs or rafters, as they are the right distance apart to take 

 the width of the paper. This insures a tight paper wall. The 

 paper is covered with planed pine boards, giving a smooth sur- 

 face to the inside of the building. This gives a tight dead air 

 space over the whole building, walls and roof. A 4x4 inch 

 plate, supported by studs, run through the centre of the building.
