Buster Bear in "Buster Bear Is A Fallen Hero"

He hadn't known that Buster could climb. But Buster is a splendid climber, especially when the tree is big and stout as this one was, and now he went up after Chatterer, growling angrily.
How Chatterer did wish that he had kept his tongue still! He ran to the very top of the tree, so frightened that his teeth chattered, and when he looked down and saw Buster's great mouth coming nearer and nearer, he nearly tumbled down with terror. The worst of it was there wasn't another tree near enough for him to jump to. He was in trouble this time, was Chatterer, sure enough! And there was no one to help him.
