Fragmentary Blue

        Why make so much of fragmentary blue
        In here and there a bird, or butterfly,
        Or flower, or wearing-stone, or open eye,
        When heaven presents in sheets the solid hue?

        Since earth is earth, perhaps, not heaven (as yet)—
        Though some savants make earth include the sky;
        And blue so far above us comes so high,
        It only gives our wish for blue a whet.
