DINOSAUR DO'S AND DON'TS

It's unfortunate that two different authors had the same bad idea--and it was published--in the same season. But about all this adds to Syd Hoff's Dinosaur Do's and Don't's (p. 1120, J-356) is silly rhymes to go with ""DO share with others. . . DO be proud of your name. . . DON'T overeat. . . "" and other exhortations to right thinking and good behavior. If you have to choose, Polhamus at least tries harder. But our advice on both is don't.
