Song. "Yet once again, but once, before we sever"

Yet once again, but once, before we sever,
  Fill we one brimming cup,—it is the last!
  And let those lips, now parting, and for ever,
  Breathe o'er this pledge, "the memory of the past!"
  Joy's fleeting sun is set; and no to-morrow
  Smiles on the gloomy path we tread so fast,
  Yet, in the bitter cup, o'er filled with sorrow,
  Lives one sweet drop,—the memory of the past.
  But one more look from those dear eyes, now shining
  Through their warm tears, their loveliest and their last;
  But one more strain of hands, in friendship twining,
  Now farewell all, save memory of the past.
