During the middle portion of his life he was actively engaged in teaching law. Here also he showed ability. One who studied law under him and like him became chief justice of the supreme court of errors of Connecticut says that his old pupils regard his work as a teacher ""as more distinctive and weightier in influence upon human life than any other portion of his work. Probably in his day not a half dozen teachers of the law in our country could be placed in his class"" ("American Bar Association Journal", February 1927, p. 74).
