Mutability

.  From low to high doth dissolution climb,
 And sink from high to low, along a scale
 Of awful notes, whose concord shall not fail;
 A musical but melancholy chime,
 Which they can hear who meddle not with crime,
 Nor avarice, nor over-anxious care.
 Truth fails not; but her outward forms that bear
 The longest date do melt like frosty rime,
 That in the morning whitened hill and plain
  And is no more; drop like the tower sublime
  Of yesterday, which royally did wear
  His crown of weeds, but could not even sustain
  Some casual shout that broke the silent air,
  Or the unimaginable touch of Time.
