Moore (Sunflakes, 1992, etc.) produces a new, small volume of poems that fits nicely in the hand. Each poem--none longer that three pages and most only two--is, like the title, a reflection on nature. Some mourn, and some rejoice, but all share the response to what Moore sees before her: a frozen waterfall, a full moon, a thunderstorm. Environmental messages are occasionally heavy-handed (""Unpoison the sea!"" and ""Where are the frogs?""), and the use of exclamation points makes for unnecessary clunks most of the time. ""The Automated Bird Watcher"" is hilarious (""Press One/To see the clutch of/eggs she laid""); ""Pilgrim Flower"" reminds readers, exquisitely, that the pilgrims brought the wildflower Queen Anne's Lace to these shores.
