FIRE QUENCHED. 55 



Q. If a house be on fire, is too LITTLE water 

 worse than NO water at all ? 



A. Certainly. Unless the water be 

 supplied so plentifully as to quench the 

 fire, it will increase the intensity, like fuel. 



Q. When mil water EXTINGUISH FIRE ? 



A. When the supply is so rapid and 

 abundant, that the fire cannot convert it 

 into steam. 



Q. Does not a very LITTLE water SLACKEN the 

 heat of fire ? 



A. Yes, till it is converted into steam ; 

 but then it increases the intensity of fire, 

 and acts like fuel. 



Q. Why does the WICK of a candle (when the 

 flame has been blown out) CATCH FIRE so readily ? 



A. As the wick is already very hot, 

 a little extra heat will throw it into flame. 



Q. Why does the EXTRA heat revive the flame ? 



A. Because it again liberates the 

 hydrogen of the tallow, and ignites it. 



Q. Cannot WOOD be made to BLAZE without 

 actual contact with fire ? 



A. Yes ; if a piece of wood be held 

 near the fire for a little time it will 

 blaze, even though it does not touch the 

 fire.
