The chick outlet is made through a trap-door cut in the floor at the 

 edge of the front runner and at the outer edge of a middle 2" x 4" joist. 

 (Fig. 97.) A run-way with cleats supported at the upper end to the 2" 

 X 4" joist leads to the ground at the edge of the house. The back of 

 the run-way is closed with boards, thereby keeping the chicks on the 

 run- way and making it possible to close them out from under the house. 

 This is desirable until they have learned to return to the house of their 

 own accord. 



After the house is closed and doors and windows fitted and hung, 

 the heater is put in place. To do this a circular opening, 8J inches 

 in diameter, is cut in the floor. The center of this opening is 19 inches 

 from the back of the house and four feet from either side, inside measure- 

 ment. The chick guard fits into this opening and telescopes over a

connecting collar which in turn fits over the collar to the super-chamber 

 of the heater box. The burner box is slid into the back runner of the 

 house and held in place with the top f " from the floor, by a wire running 

 around the loose end of the box and supported above by staples driven 

 into the floor. (Fig. 98.) The stem is telescoped down over the collar. 

 The radiator is telescoped over the top of the stem. The opening for the 

 vent pipe in the back of the house is located so as to correspond exactly 

 to the vent pipe coming out of the radiator over which it is telescoped. 

 Great care should be exerciser in installing the heater, as any loose 

 fitting connection will allow leakage of gases into the hover or brooder. 

 The hover (Fig. 99) is made of seven-eighths inch matched pine flooring, 

 planed both surfaces, and is held to the back of the house with de- 

 tachable hinges. It can be raised and held up out of the way with
