_Mother._ But, after the fire is made, we feel much heat coming from the
fire, do we not?
_Daughter._ Why, yes, mother; that is what the fire is made for. We feel
cold, and we want a fire to make us warm; and when the fire is made, it
sends out heat, and makes us warm.
_Mother._ Well, now, where can the heat come from? You know what fire is
made from, do you not?
_Daughter._ Certainly, mother; the fire is made of wood, or of coal.
_Mother._ But is the wood or the coal warm before the fire is made?
_Daughter._ No, mother, the wood and the coal come from the cold
wood-house, or the cellar, and they are both very cold.
_Mother._ And yet, the wood and the coal become very hot when they are
on fire.
_Daughter._ O yes, mother, so hot that we cannot touch them with our
hands, and we have to take the shovel or the tongs to move them.
_Mother._ And do they burn the shovel and the tongs, my dear?
_Daughter._ Why, no, mother; if they did, the shovel and the tongs would
be of little use in stirring the fire.
_Mother._ Can you think of any reason why they do not burn the shovel
and the tongs?
_Daughter.
