20 Director's Report of the 



part occupied by a hot-water heater and coal. From the incubator 

 room two eight-inch ventilating pipes run to the loft. The first 

 floor is used for a work room and one part as a sleeping room for 

 the poultry man. The loft is used for storage. 



Towards the end of the brooder wing are four pens in which can 

 be used separate lamp brooders. A row of eight brooders is 

 heated by pipes of hot water. Back of these brooders is a sunken 

 passage-way connected with the heater room of the basement. 

 This is covered by a trap floor which may be hooked back when 

 desired. When working in this passage-way the brooders are at 

 the height of an ordinary work bench. Four of the brooding 

 chambers are 2 ft. by 3 ft. and four are 2 ft. by 4 ft. on the floor. 

 Four flow pipes of hot water run through the brooders imme- 

 diately over the chicks and two larger return pipes run underneath 

 the tight floor. The brooders are separated by air chambers or 

 boxes from which fresh air is admitted at each end of the brooder 

 chamber through screened covered openings. Doors from the air 

 box open into the passage-way so that pans of hot water to supply 

 moisture may be placed on the return pipes. 



These air boxes are not separated from the long inclosed space 

 under the brooders through which the return pipe runs. A dam- 

 per admits fresh air from the passage-way to the space under each 

 brooder so that a current of air may pass under the floor of the 

 brooder over the return pipes, then into the air box over the 

 moisture pans and enter the brooding chamber near the flow pipes. 

 The front of the brooding chamber is open, the floor being level 

 with the floor of the pen, but can be closed when desired by a 

 door of wire netting. The rear wall, partly of glass, is securely 

 attached to the cover which is hinged and lifts against the parti- 

 tion. The brooder covers are strong so that collectively they form 

 a raised walk. Wire netting doors open into each brooder pen. 



The wing at the left contains a feed room and four pens for 

 breeding stock. This wing has a tight-board ceiling. Trap doors 

 open into the loft and ventilator pipes extend through the roof. 

 A pipe connected with the water heater runs through this wing
