"Who, me?" A round-faced little Munchkin boy stuck his head in the door and regarded Professor Wogglebug solemnly. He was working his way through the Professor's Athletic college, and one of his duties was to wait upon this eminent educator of Oz. "Certainly not!" snapped Professor Wogglebug. "You're a nobody or a nothing. Stop gaping and fetch me my hat. I'm off to the Emerald City. And mind the pupils take their history pills regularly while I'm gone," he added, clapping his tall hat Zif held out to him on the back of his head. "Yes, sir!" said the little Munchkin respectfully. "Don't hurry back, sir!" This last remark the Professor did not hear, for he was already half way down the college steps. "Ozma will be delighted with the idea. How clever I am!" he murmured, twirling his antennae and walking rapidly down the pleasant blue lane. The Professor, whose College of Art and Athletic Perfection is in the southwestern part of the Munchkin country, is the biggest bug in Oz, or in anyplace else, for that matter. He has made education painless by substituting school pills for books. His students take Latin, history and spelling pills; they swallow knowledge of every kind with ease and pleasure and spend the rest of their time in sport.
