Not every old man with ragged trousers is a bad old man: some are bone-and-bottle men, and have little dogs of their own; and some are gardeners; and a few, a very few, are wizards prowling round on a holiday looking for something to do. This one was a wizard, the one that now walked into the story. He came wandering up the garden path in a ragged old coat, with a pipe in his mouth, and an old green hat on his head. If Rover had not been so busy barking at the ball, he might have noticed the blue feather stuck in the back of the green hat, and then he would have suspected that the man was a wizard, as any other sensible little dog would.
