His labors as editor did not estrange him from the law. About this period he became for a short time one of the justices of the Marine Court, a tribunal now shorn of its early dignity. In 1815 he appeared as author of a treatise on jurisprudence. This was a "Digest of the Law of Maritime Captures and Prizes." In the judicial inquiries incident to the administration of the Laws of War--still maintained by the Christian world--such a treatise was naturally of much practical utility. It may also claim the palm of being among the earliest juridical productions of our country. Nor, indeed, has it been without the disinterested praise of foreign nations. Mr. Reddie, of Edinburgh, in his recent work on Maritime International Law, says, "Although it cannot be strictly called a valuable accession to the legal literature of _Britain_, it gives us much pleasure to record our opinion, that, in point of learning and methodical arrangement, it is very superior to any treatise on this department of the law which had previously appeared in the English language."[236] No American contribution to jurisprudence so early as 1815 has received such marked commendation abroad. Kent and Story had not then produced those works which have secured to them their present freehold of European fame. [236] Maritime International Law, Vol. II. p. 298. In 1816 he became Reporter to the Supreme Court of the United States, which office he held till 1827. His Reports are in twelve volumes, and embody what may be called the _golden judgments_ of our National Judicature, from the lips of Marshall, Livingston, Washington, Thompson, and Story. Mr. Wheaton's time was not absorbed by these official duties. He entered much into the practice of his profession. His name appears as counsel in important causes at Washington. He was editor of divers English law books, republished in this country, with valuable notes. On several literary occasions he pronounced discourses of signal merit. One of these, in 1820, before the Historical Society of New York, touches upon his favorite theme, with which his name is now so firmly connected, the Law of Nations; another, in 1824, at the opening of the New York Athenæum, takes a rapid survey of American literature. In 1826 he published his Life of that great lawyer, William Pinkney. It is also understood that during all this period he was a frequent contributor to the "North American Review." Nor did these accumulated labors, literary and juridical, keep him from other services. He was a member of the Legislature of New York, and in 1821 held a seat in the Convention which remodelled the Constitution of that State. In 1825 he was placed on the commission for revising the statutes of New York. This was the first effort of any State professing the Common Law to reduce its disconnected and diffusive legislation to the unity of a code. Thus is his name associated with one of the most important landmarks in American law.
