Book excerpt: Here are modern poems chosen for their individual excellence and their special appeal to young people. Exciting photographs accent the contemporary tone of the collection. From lighthearted Phyllis Mc-Ginley to pessimistic Ezra Pound; from the lyricism of Edna St. Vincent Millay to the vigor of Lawrence Ferlinghette; from Carl Sandburg on loneliness to Paul Dehn on the bomb -- such is the range. The little known or unknown poet and the widely recognized appear side by siide. Whatever the subject matter -- pheasant or flying saucer; lapping lake water or sonic boom; a deer hunt, a basketball, or a bud -- it is all poetry reflecting today's images and today's moods. The editors spent several years bringing together 1200 poems they considered fine enough to include, then slowly and carefully sifted out of 114 which appear in the book. Readers of Reflections on a Gift of Watermelon Pickle . . . and Other Modern Verse may well be tempted by Eve Merriam's suggestion in "How to Eat a Poem" center Don't be polite Bite in. Pick it up with your fingers and lick The juice that may run down your chin. It is ready and ripe now, whenever you are.
