"This letter, Richard Strahan, will only come under your eyes in case the plans and the hopes which I have formed for my earthly future should be frustrated by the death on which I do not calculate, but against the chances of which this will and this letter provide. I am about to revisit England, in defiance of a warning that I shall be there subjected to some peril which I refused to have defined, because I am unwilling that any mean apprehension of personal danger should enfeeble my nerves in the discharge of a stern and solemn duty. If I overcome that peril, you will not be my heir; my testament will be remodelled; this letter will be recalled and destroyed. I shall form ties which promise me the happiness I have never hitherto found, though it is common to all men,--the affections of home, the caresses of children, among whom I may find one to whom hereafter I may bequeath, in my knowledge, a far nobler heritage than my lands. In that case, however, my first care would be to assure your own fortunes. And the sum which this codicil assures to my betrothed would be transferred to yourself on my wedding-day. Do you know why, never having seen you, I thus select you for preference to all my other kindred; why my heart, in writing thus, warms to your image? Richard Strahan, your only sister, many years older than yourself--you were then a child--was the object of my first love. We were to have been wedded, for her parents deceived me into the belief that she returned my affection. With a rare and nobler candour, she herself informed me that her heart was given to another, who possessed not my worldly gifts of wealth and station. In resigning my claims to her hand, I succeeded in propitiating her parents to her own choice. I obtained for her husband the living which he held, and I settled on your sister the dower which, at her death, passed to you as the brother to whom she had shown a mother's love, and the interest of which has secured you a modest independence. "If these lines ever reach you, recognize my title to reverential obedience to commands which may seem to you wild, perhaps irrational; and repay, as if a debt due froth your own lost sister, the affection I have borne to you for her sake." While I read this long and strange letter, Strahan sat by my side, covering his face with his hands, and weeping with honest tears for the man whose death had made him powerful and rich. "You will undertake the trust ordained to me in this letter," said he, struggling to compose himself. "You will read and edit this memoir; you are the very man he himself would have selected. Of your honour and humanity there can be no doubt, and you have studied with success the sciences which he specifies as requisite for the discharge of the task he commands."
