Last-Minute Message For a Time CapsuleI have to tell you this, whoever you are:that on one summer morning here, the oceanpounded in on tumbledown breakers,a south wind, bustling along the shore,whipped the froth into little rainbows,and a reckless gull swept down the beachas if to fly were everything it needed.I thought of your hovering saucers,looking for clues, and I wanted to write this down,so it wouldn't be lost forever - -that once upon a time we hadmeadows here, and astonishing things,swans and frogs and luna mothsand blue skies that could stagger your heart.We could have had them still,and welcomed you to earth, butwe also had the righteous oneswho worshipped the True Faith, and Holy War.When you go home to your shining galaxy,say that what you learnedfrom this dead and barren place isto beware the righteous ones.
