I sometimes hold it half a sin
  To put in words the grief I feel;
  For words, like Nature, half reveal
And half conceal the Soul within.

But, for the unquiet heart and brain,
  A use in measured language lies;
  The sad mechanic exercise,
Like dull narcotics, numbing pain.

In words, like weeds, I'll wrap me o'er,
  Like coarsest clothes against the cold:
  But that large grief which these enfold
Is given in outline and no more.
