Mr. Church,  
  Dear Sir:

I have not, as yet, received any proof of the Carol of Harvest.

I neglected to mention, in my former note, that I reserve the right of incorporating & printing the Carol, in future, in the copyrighted collection of Leaves of Grass. I shall not avail myself of this right, however, within six months following Sept. 1, 1867, without permission of the publishers of the Galaxy.

Walt Whitman.
