The great ode by Wordsworth

There was a time when meadow, grove, and stream,
       The earth, and every common sight,
                          To me did seem
                      Apparelled in celestial light,
            The glory and the freshness of a dream.
It is not now as it hath been of yore;—
                      Turn wheresoe’er I may,
                          By night or day.
The things which I have seen I now can see no more
