With one-color silhouette-like prints whose chief virtue is their modesty, this is not the lesson in ecology and plant care the title might suggest but a sort of poem of ""wonderment"" which might work better as an exercise in method dramatics. The rhymed questions range from momentarily seductive (""Is snow like a sweater,/ only wetter?// Is ice like my slicker,/ only thicker? . . . Does rain tickle// Do bugs itch?/ Which?"") to plain silly (""Are you happy/ when you're sappy?""). But mostly we're reminded--by lines like ""Is it nice/when robins/build nests in you?/ And squirrels, too?""--of the ludicrousness of the question, even for those whom poems are made by. . . .
