The big bear tended the fire, breaking up the dry branches by holding one end and stepping on them, like people do. He was good at keeping it going at the same level. Another bear poked the fire from time to time but the others left it alone. It looked like only a few of the bears knew how to use fire and were carrying the others along. But isn’t that how it is with everything? Every once in a while, a smaller bear walked into the circle of firelight with an armload of wood and dropped it onto the pile. Median wood has a silvery cast, like driftwood.
