sheet of tin is nailed to the rear wall of the house to hold the outlet 

 pipe in place. P is the vent pipe with a T on the end. Q is a guard 

 to keep the hover from resting down upon the radiator; R is the gaso- 

 line tank; 5 the filler plug; T the filler cap; and U is the gasoline outlet 

 pipe fastened with a nut on each side of the tin. 



Galvanized iron is the material used, except the tin in the diaphragm L, 

 the perforated tin for chick guard H, the Dangler burner B, and pipe C. 

 Six and one-half feet of |" gas pipe, with elbows and couplings, are needed 

 to make the connections between the gasoline tank, R, and the pipe C. 

 This length of pipe is also provided with a globe valve as illustrated 

 in Fig. 95. 



Note. — The gasoline brooding system which is here described and shown, 

 is covered by no existing patent as far as we know. Any person or manufacturer 

 is free, so far as we are concerned, to use these plans, but must assume all risk 

 of litigation because of alleged infringements. This system of brooding by the 

 use of gasoline-heated colony houses is given free to the public, with the request 

 that credit shall be given by manufacturers by placing the following statement 

 on all heaters which they make :

OPERATION OF THE GASOLINE BROODER 



The brooder is run for the first week or ten days so that the thermo- 

 meter, located as mentioned above, gives a reading of 90 degrees F. 

 At the same time, the thermometers placed under other parts of the 

 hover would show a range of temperature from 90 degrees to 103 degrees 



F., making it possible 

 for the chicks to get 

 almost any degree of 

 temperature from 60 

 degrees out in the 

 room to 103 degrees 

 under the hover near 

 the collar. 



In Fig. 103 is shown 

 the way the tank is 

 filled from the rear of 

 the house. The burner
