the top of your chimney (if you use one), and the iron 

 floor of the hot air chamber. To the top of the three 

 sides of this frame, which are of equal hight, is nailed 

 the iron floor of the hot air chamber. This is a sheet 

 of galvanized iron thirty-six by forty-two inches. 

 Above this iron floor is fastened a frame of strips of 

 board two inches wide to form the outer walls of the 

 heat chamber, openings being left for the inlets. It is 

 nailed fast to the iron in the back, and through the 

 iron to the lower frame on the front and sides. On 

 this frame is laid the floor of the brooder proper, 

 which is made of matched boards. Before the floor is 

 made fast to the frame a circular hole must be made 

 in the center to receive the iron ring which conducts 

 the heat into the brooding chamber. This hole in the 

 wooden floor is nine inches in diameter. 



The front and sides of the brooding chamber form 

 a movable three-sided frame, firmed together at the 

 upper portion of the rear third by a strip of inch stuff. 

 In the front section of this frame is a six by eight-inch 

 window, and a door, zc. The door is hinged, and 

 fastens with a button. The window is beveled at the 

 the top to shed rain, and is screwed to the frame. A 

 cheaper and homelier way would be to set two lights 

 of glass in the wood of the frame. 



The roof is made m two pieces. The main or front 

 section is removable, and is held in place by cleats, as 

 shown in cut. When the brooder is in outdoor use this 

 seccion of the roof, v, is secured to the sides of the 

 brooding chamber by screws through the side cleats. 

 The chamber sides are screwed to the base or floor 

 cleats. A window ten by eighteen inches is provided 

 in this part of the roof. The rear section of the roof is 

 a movable board fitted and cleated and held in place by 

 the cleats, with the additional security of a hook and 

 screw eye on either end to keep animals from breaking
