Plotz' latest topical anthology features poems about teachers, school children, campus scenes, classroom scenes, scholars, college radicals (an editor's footnote to Daniel Hoffman's ""The Princess Cassamassima"" explains that ""The Princess Cassamassima, the central character in the Henry James novel of that name, involved herself in revolutionary activities""), commencement platitudes, and the folly (to William Blake) of going to school on a summer morn. Plotz arranges the selections in five sections, from one called ""To Girlhood, Boyhood Look, the Teacher and the School,"" to the final ""The Company of Scholars""; and she throws together a range of poets from Mother Goose, Edward Lear, and Phyllis McGinley to Sappho, May Sarton, and Emily Dickinson. With four selections each, Richard Lattimore's commemorative poems, Reed Whittemore's wry reflections, and Edgar Lee Masters' Spoon River excerpts lead the count. The subject is not the stuff of passion, and the overall tone is relatively staid. The whole concept represents an odd approach to poetry.
