It was at his option, in 1846, to accept the highest legal position in the country, setting aside the bench, and the one which undoubtedly would most have gratified his professional aspirations. President Polk, with whom he had been associated on the most friendly terms in Congress, now offered him the post of attorney general of the United States. “In tendering to you this position in my cabinet,” writes the President, “I have been governed by the high estimate which I place upon your character and eminent qualifications to fill it.” The letter, in which this proposal is declined, shows so much of the writer’s real self that we quote a portion of it. “Although the early years of my manhood were devoted to public life, it was never really suited to my taste. I longed, as I am sure you must often have done, for the quiet and independence that belong only to the private citizen; and now, at forty, I feel that desire stronger than ever. “Coming so unexpectedly as this offer does, it would be difficult, if not impossible, to arrange the business of an extensive practice, between this and the first of November, in a manner at all satisfactory to myself, or to those who have committed their interests to my care, and who rely on my services. Besides, you know that Mrs. Pierce’s health, while at Washington, was very delicate. It is, I fear, even more so now; and the responsibilities which the proposed change would necessarily impose upon her ought, probably, in themselves, to constitute an insurmountable objection to leaving our quiet home for a public station at Washington. “When I resigned my seat in the Senate in 1842, I did it with the fixed purpose never again to be voluntarily separated from my family for any considerable length of time, except at the call of my country in time of war; and yet this consequence, for the reason before stated, and on account of climate, would be very likely to result from my acceptance. “These are some of the considerations which have influenced my decision. You will, I am sure, appreciate my motives. You will not believe that I have weighed my personal convenience and case against the public interest, especially as the office is one which, if not sought, would be readily accepted by gentlemen who could bring to your aid attainments and qualifications vastly superior to mine.”
