Emily Dickinson - I'll tell you how the sun rose lyrics

I'll tell you how the sun rose, - A ribbon at a time. The steeples swam in amethyst, The news like squirrels ran. The hills untied their bonnets, The bobolinks begun. Then I said softly to myself, "That must have been the sun!" But how he set, I know not. There seemed a purple stile. Which little yellow boys and girls Were climbing all the while Till when they reached the other side, A dominie in gray Put gently up the evening bars, And led the flock away.
