Mr. Boutwell's pleas and arguments have with few exceptions been published in book or pamphlet form, or both, and form of themselves a most valuable and interesting addition to legal literature. They bear evidence of a profound knowledge of the law, of vast research and of great literary ability. Among others may be mentioned those upon a petition to the Massachusetts Legislature for the removal of Joseph M. Day as judge of probate and insolvency for Barnstable County in March, 1881; in the matter of the Pacific National Bank of Boston before the banking and currency committee of the United State House of Representatives, March 22, 1884; and for the claimant in the case of the Berdan Fire-Arms Manufacturing Company of New York vs. the United States. He is the author of "Educational Topics and Institutions," 1859; "Speeches Relating to the Rebellion and the Overthrow of Slavery," collected and published in 1867; "Why I am a Republican," a history of the Republican Party to 1884, republished in 1888; "The Lawyer, Statesman and Soldier," 1887; and the "Constitution of the United States," embracing the substance of the leading decisions of the Supreme Court in which the several articles, sections and clauses have been examined, explained and interpreted, 1896. In 1888 he wrote a pamphlet on "Protection as a Public Policy," for the American Protective Tariff League; on April 2, 1889, he read a paper on "The Progress of American Independence," before the New York Historical Society; and in February, 1896, he published a pamphlet on "The Venezuelan Question and the Monroe Doctrine." Mr. Boutwell has probably argued more cases involving international law than any other living man, and in this department ranks among the ablest and strongest that this country has ever produced. For more than forty years he was a prominent figure before the bar of the United States Courts at Washington, where he achieved eminence as an advocate of the highest ability. He was uniformly successful, and won a reputation which was not confined to this country. He is an authority on international and constitutional law. His published writings stamp him as a profound student of public questions and a man of rare literary culture and genius. He was a strong Abolitionist, and as lawyer, statesman and citizen he has faithfully and efficiently performed his duties and won the confidence of both friends and opponents. In politics he has been a leader of the Republican Party since its organization. He was a delegate to the Chicago Conventions of 1860 and 1880, and was chosen a delegate to the Baltimore Convention of 1864, but declined. He was elected a member of the American Academy of Arts and Sciences in 1857 and of the Phi Beta Kappa Society of Harvard College in June, 1861, at which time he delivered the Phi Beta Kappa oration. In 1851 Harvard conferred upon him the honorary degree of LL. D., and in 1861 he was a member of the Peace Congress at Washington.
