**Wider in appeal, in our opinion, than The Twenty One Balloons and tops in nonsense value this story of an elderly scientist, an inventive youngster and the anti-magnetic element - Furloy- should top the juvenile humor list. Peter Graves, leader of the Growlers and highly respected for his ingenuity in practical matters, always knew that strange things were going on in the Horrible House of Houghton, from which strange gases and sparks were seen to emerge. And when Peter came face to face with the elderly Houghton himself, he felt he was in the presence of a very mad scientist. However, Peter's curiosity was too much for him and he saw Houghton's great invention -- Furloy -- an element with a minus weight. Houghton and Peter are soon trying flying experiments until an escaped Furloy invention destroys the house. How the pair earn money to rebuild the house by winning prize money in athletic and magic contests with concealed Furloy balls, and finally start a Furloy Age makes a wacky, hilarious yarn.
