Harvey Potter's Balloon FarmHardcover, 29 April 1994

Harvey Potter was a very strange fellow indeed. He was a farmer but not like any farmer you've ever met. He didn't grow corn, okra, or tomatoes. Harvey Potter grew balloons. No one knew exactly how he did it, but with the help of the light of a full moon, one friendly child catches a peek of just how Harvey potter does it. And keeps some magic for herself.
