'Big Bossie, Big Bossie, how silly of me,/ Have you seen what I did with my rusty old key?'/ 'Of your key,' said Big Bossie, 'I've seen not a sign,/ But this hat must be yours. It's surely not mine!'"" In her search for her house key forgetful goose Gertrude visits not only Bossie the cow but also Rushmore the horse, Curlpink the Pig, Teedaweet the Sparrow, Purmeece the Cat, and Digwell the Dog. And though none has seen the key, each comes up with a piece of her wardrobe -- hat, shawl, socks, shoes, bag and fan. But as each woodenly rhymed six-line conversation is almost identical to the one before, you'll be inclined to go along with Gertrude's exasperated ""Will this forgetting of mine never stop?"" Those enticed by Paul Galdone's gay costuming to continue the search will at last find Gertrude's key in her own door lock.
