COCKATOOS

Weary of hearing the same greeting day after day--""Good morning, my fine feathered friends!""--Professor Dupont's ten cockatoos fly the coop. He searches every room of his elaborate, old house without spotting them--but readers will, for they're all there, slightly concealed. Blake's illustrations are, as ever, funny and filled with lively detail; but while this doubles as a counting book, it's as airy and weightless as a feather.
