When we come to the problem of fire, we always use parts of Miss Dopp's story of _The Tree-Dwellers_. If the children are asked if they ever heard of fire that comes by itself, or of things being burned by fire that no human being had anything to do with, one or two are sure to suggest lightning. They will tell that lightning sometimes sets trees on fire, that thunderstorms generally come after hot dry weather, and that if lightning struck a tree with dry stuff about the fire would spread, and the long-ago people would run away. A question from the teacher as to what these people might think about it may bring the suggestion of a monster; if not, one only has to say that it must have seemed as if it was eating the trees to get "They would think it was a dreadful animal." Then the story can be told of how the boy called Bodo stopped to look and saw the monster grow smaller, so he went closer, fed it on wood, and liked to feel its warm breath after the heavy rain that follows thunder--why had the monster grown smaller?--found that no animal would come near it and so on. We never tell of the "fire country," though sometimes the children read the book for themselves a little later. We have never succeeded in making flames, but it is thrilling to get sparks from flint. Once a child brought an old tinder box with steel and flint, but even then we were not skilful enough to get up a flame. Still it is something to have tried, and we are left with a respectful admiration for those who could so easily do without matches. What made these long-ago people think of using their fire to cook food? Our children have suggested that a bit of raw meat fell into the fire by accident, and we have also worked it out in this way. We were pretending to warm ourselves by the fire, and I said my frozen meat was so cold that it hurt my teeth. "Hold it to the fire then." We burned our fingers, and sticks were suggested, but we sucked the burnt fingers, and I said, "it tastes good," and the children shouted with glee "Because the meat's roasted really." Then something was supposed to drop, and the cry was "Gravy! catch it in a shell, dip your finger in and let your baby suck it." A small shell was suggested, and the boy who said "And put a stick in for a handle" was dubbed "the spoon-maker." At that time we were earning names for ourselves by suggestions; we started with Fair Hair, Curly Hair, Big Teeth, Long Legs, and arrived at Quick Runner, Climber, and even Thinker.
