10. All the residue of my estate, real and personal, I bequeath and devise to my executor in trust, to be sold at such time and in such way as he shall think best, the proceeds to be distributed in two equal moieties, as follows: One moiety to be paid my sister, Julia Hastings, wife of John Hastings of San Francisco, Cal., for her sole and exclusive use; or, should she die before me, then in equal portions to her three daughters or the survivor, each portion to be for the sole and exclusive use of such daughter. The other moiety to be paid to the President and Fellows of Harvard College, in trust, for the benefit of the College library, my desire being that the income should be applied to the purchasing of books relating to politics and fine arts. This bequest is made in filial regard for the College. In selecting especially the library, I am governed by the consideration that all my life I have been a user of books, and having few of my own, I have relied on the libraries of friends and on public libraries; so that what I now do is only a return for what I have freely received. 11. I appoint Francis V. Balch executor of this will, and desire that the trustees of my papers may be exempt from giving bonds. In testimony whereof, I hereunto set my hand this second day of September, 1873, at Boston.
