Buster Bear in "Buster Bear Is A Fallen Hero"

A dozen times a day Buster would hear them screaming this. He would grind his teeth and glare up at them, but that was all he could do. He couldn't get at them. He just had to stand it and do nothing. But when impudent little Chatterer the Red Squirrel shouted the same thing from a place just out of reach in a big pine-tree, Buster could stand it no longer. He gave a deep, angry growl that made little shivers run over Chatterer, and then suddenly he started up that tree after Chatterer. With a frightened little shriek Chatterer scampered to the top of the tree.
