When Stan Groundhog retires as weather forecaster for the Claws and Paws daily (scene of Hall's Headlines, 1973), his job is sought by Caroline Porcupine, who has studied meteorology. (The science of meteors? ""No,"" snaps Caroline. ""The science of weather!"") A perfect record for a week and it's hers, says editor Theodore Cat--though Caroline's friends point out that Stan was often wrong every day for a week. But Caroline's scientific methods serve her well, and even the snow she's predicted for the last day descends on schedule--smack in the middle of both summer and a feather shower her sympathetic but skeptical friends have staged from the roof. With the whole staff romping outdoors afterwards, it's all good-natured and light-hearted enough to rate a filler spot, even though it won't make headlines.
