a rain storm because it is handier to do so than to enter the house. The 

 high runners also make the house colder in winter because more difficult 

 to bank up to prevent the wind from blowing under the house. 



10. Economy of fuel. 



The cost for fuel is about the same for supplying heat to a given 

 number of chickens by the gasoline system as it is where kerosene is 

 used. The price per gallon for gasoline, however, is several cents higher 

 than kerosene. A little less gasoline is used for one flock of 200 chickens 

 than kerosene for heating four brooders containing 50 chickens each. 

 In moderately cold weather it costs about seven cents per day to heat a 

 brooder house containing 200 chickens. The larger the number of 

 chickens, the less the cost of fuel. This is due to the warming effect 

 of the heat radiated from the bodies of the chickens. 



11. Safety from fire is an important consideration of the gasoline 

 system of heating. 



There is less danger from fire with gasoline than there is with kero- 

 sene when the system is properly understood, which knowledge may 

 readily be acquired by any one who is capable of being entrusted with 

 kerosene heated brooders. The 

 gasoline system has the advan- 

 tage of safety in the fact that 

 only one source of fire is possi- 

 ble with 200 chickens, whereas, 

 with small brooders there are 

 four possible fires with four 

 flocks of 50 chickens each. The 

 great danger of fire from kero- 

 sene comes during cold weather 

 when the flames are turned up 

 high in order to secure enough 

 heat to keep the chickens warm 

 or when the wicks are not prop- 

 erly trimmed, or where drafts 

 occur, which start the forma- 

 tion of soot, which in turn takes 

 fire, unsoldering the lamp and 

 other parts, thus reaching the 

 woodwork. The blue flame of 

 the gasoline burner provides an abundance of heat without the necessity 

 of turning the burner too high even in very cold weather.

 an even flow of gasoline and steady flame.
