At Half-Past Three A Single Bird By Emily Elizabeth Dickinson

 At half-past three a single bird
    Unto a silent sky
    Propounded but a single term
    Of cautious melody.

    At half-past four, experiment
    Had subjugated test,
    And lo! her silver principle
    Supplanted all the rest.

    At half-past seven, element
    Nor implement was seen,
    And place was where the presence was,
    Circumference between.
