'"Hum" is the imaginary playmate of childhood, for 'out of every three million babies,' the author writes, 'two million nine hundred and ninety nine thousand, nine hundred and ninety-nine are born with a 'Hum' kind of person hovering around them. And the other one? He acquires it before he is two.' This is a whimsical story that should appeal to the imaginations of children, and has its setting in the Australian bush.'
