It was both my purpose and desire to pass the remainder of my days in kind and friendly social intercourse with the friends of my youth and of my riper years, when invited by the President of my choice, under circumstances which a sense of duty rendered irresistible, to accept the mission to London. This purpose is now postponed, not changed. It is my intention to carry it into execution, should a kind Providence prolong my days and restore me to my native land. I am truly sorry not to be able to accept your invitation. Such are my engagements, that I can appoint no day for the dinner when I could, with certainty, promise to attend. Besides, a farewell dinner is at best but a melancholy affair. Should I live to return, we shall then meet with joy, and should it then be your pleasure to offer me a welcome home dinner, I shall accept it with all my heart. I cherish the confident hope that during my absence I shall live in your kindly recollection, as my friends in Lancaster County shall ever live in my grateful memory. Cordially wishing you and yours, under the blessing of Heaven, health, prosperity and happiness, I remain Your friend and fellow-citizen, JAMES BUCHANAN. Here, in regard to this English mission and other matters, Mr. Buchanan’s correspondence with his niece, Miss Lane, from February to August, 1853, will show how tender and how important had now become their relations to each other. [TO MISS LANE.] WHEATLAND, near LANCASTER, Feb. 3, 1853. MY DEAR HARRIET:— I have passed the time quietly at home since I left Philadelphia, toiling night and day, to reduce the pile of letters which had accumulated during my absence. I have got nearly through and intend to pass some days in Harrisburg next week. I have literally no news to communicate to you. Miss Hetty and myself get along to a charm. She expects Miss Rebecca Parker here to-day,—the promise of Mr. Van Dyke. I hope she may come. I received a letter yesterday from Mr. Pleasanton, dated on the 31st ultimo, from which the following is an extract: “Clemmy wrote some two weeks ago to Miss Harriet asking her to come here and spend some time with us. As she has not heard from her, she supposes Miss Lane to be absent. Be good enough to mention this to her, and our united wish that she should spend the residue of the winter and the spring with us. There is much gaiety here now, though we do not partake of it. We will contrive, however, that Miss Lane shall participate in it.”
