ALVIN'S FAMOUS NO-HORSE

An earnest little lecture of a book (one of the Redfeather series) whose two morals are: ``If at first you don't succeed...'' and ``If you want to learn how to do something, watch an expert.'' It's an amiable enough story about third-grader Alvin, who can't draw but must produce something to be displayed on Parents' Night at school—but it's also preachier than any young reader is likely to sit still for. Illustrations not seen. (Young reader/Fiction. 6- 9)
