With sincere regard, your friend, FRANK PIERCE. [MARCY TO BUCHANAN.] WASHINGTON, March 5, 1853. MY DEAR SIR:— If not a matter of strict duty, I choose to regard it as a proper thing to explain my movements to you. A few days after the late Presidential election, I went south with my son Edmund, about whose condition as to health I had become alarmed, and am still very solicitous. In the first week of February, he took a steamer for some of the West India Islands, and I concluded it to be my duty to return to my deserted family at Albany. I arrived at Richmond, Virginia, about the 20th of February, with a disposition to pass on to the North without going through Washington. As I had never done anything at that place for which I ought to be ashamed (or rather I thought I had not), it appeared to me it would be cowardly to run around or through it. I was very much inclined to go and perchance to stop there a few days. The doubts which distracted me in regard to my course were almost entirely removed by a letter from a person whom I had never seen, suggesting that it might be well for me to be in Washington about the 20th ult. On my appearance there a rumor suddenly arose that I was certainly to be one of the new cabinet, and the same liberty was taken with the names of several other persons. I have heard in an unauthentic way that you had been wise enough to take precautions against such a use of your name. It is now generally believed here, and I believe it myself, that I may be in the cabinet of the incoming administration, and (to confess all) I have been weak enough to make up my mind to accept a seat if offered one in it. Should it be the place you filled with so much ability, I may be rash enough not to decline it. I have told you all; here I am and here I am likely to be, for a brief period at least. I do not think you will approve of what I have done. I hope you will not severely censure me, or the judgment which will put me where I expect to be. If it is an error, either on my part or that of another, there are some circumstances to excuse it, but I have not time to present them in detail. I hope to have a frank and free intercourse with you. I will go further, I hope to have—what I know I shall much need—the aid in some emergencies of your greater experience and better knowledge. It will give me sincere pleasure to hear from you. Yours truly, W. L. MARCY.
