(b) From 1802 to 1804, Mrs. Trimmer edited _The Guardian of Education_ (published monthly) which exercised a kind of censorship over children’s books. A reference by Mrs. T. to Perrault’s _Tales_, which she had read as a child, called forth the criticism of a correspondent who denounced “Cinderella” in particular as encouraging envy, jealousy, vanity and other evil passions in children. Mrs. Trimmer’s principles forced her to agree with this stern moralist.
