The Incubator House and Poultryman's Residence. 



Last fall the Station constructed an incubator cellar with a 

 residence for the poultryman above it. The building is located 

 conveniently near the poultry buildings and runs, and yet suffi- 

 ciently removed to make it desirable as a residence. 



Living so handy enables the poultryman to be in close touch 

 with his work during the incubating and brooding season. 

 While the incubators are in operation he inspects them at 5 

 o'clock in the morning and between 8 and 9 P. M. During the 

 breeding period and while the chickens are on the range, it is 

 desirable to have them liberated and fed as soon as they can 

 see to eat in the morning, and not shut in at night until just 

 before dark. This makes a long day for the caretaker, and the 

 handy location of this house enables him to do his work more 

 easily and satisfactorily. 



The incubator cellar is 30 feet square, inside measurements, 

 and 7 feet in the clear. Its walls are of concrete material 

 and the floor is cemented. Two large cellar windows are in 

 each of the west, north and east sides, but none on the south, as 

 the warmth of the sun, admitted by windows in that side, would 

 be liable to raise the temperature of the cellar during the middle 

 of the day. The six windows give good light for caring for 

 incubators and handling the eggs. Broad shutters darken the 

 room when the eggs are being tested. The building has two 

 chimneys and each has two separate flues. One flue in each 

 chimney connects with the house fires and the other ventilates 

 the cellar through adjustable openings. The chimneys being 

 warmed by the up-stair fires cause the ventilating shutes to draw 

 and ventilate the cellar quite well. In addition to these venti- 

 lators, the double doors in the rollway have openings 10 inches 

 square with adjustable slides, and when necessary they are used 

 to give complete ventilation. In the mornings, when the lamps 

 are being cleaned and trimmed, and the out-of-door temperature 

 is normal, both of the rollway doors are left partially open so as 

 to quickly remove the odors of the lamps. 



Thorough ventilation and a full supply of clean air to the 

 incubator cellar are imperative. The incubator room is large 

 enough to accommodate i6 of the largest size Cyphers incuba- 

 tors and leave space for passages between the machines for
